We hear a lot from the media that businesses can not find skilled labor for whatever is the latest hot job in the market place. Many of these companies refuse to retrain their current staff and instead outsource the work to contractors or move the work off shore. What Jessa Jones, Louis Rossmann and other independent business people are doing is providing the necessary training. I thank them from the bottom of my heart.
As a guy who learned how to solder in the late 50's on tube based devices, these new, tiny devices are really hard. I guess that my 68 year old eyes do not help much. I miss the days of using my 250 watt Weller gun and multi-core flux solder. I do not miss the multi-pound power transformers and the 350 volt B+ lines.
yeah I'm 26, had a lasik done a year ago, so my vision is great, tried unsoldering a 1005 resistor in an iPad today with a soldering iron, put it down after a few minute and just crushed that resistor with a sewing needle Almost impossible to work on modern electronics today without a hot air station, multiple tips and a microscope and stay sane haha
Even me after 20 yrs of soldering could learn sth. new here. love the way you explain everything completely clear. a real master at work. like your passion also. great vid, thanks ifixit for producing and sharing these. greetings from Germany
Absolutely love this series. The level of detail with which Jessa tries to explain stuff in layman's terms is amazing. I'm really looking forward to more tutorials!
I actually sent her an iphone several years back a customer of mine mangled while trying to pry out the battery of an iphone. She did an awesome job! Good video
In a way its good that the pad came off as Jessa was able to show how to remedy the situation. I'm sure that those of us that are in the electronics industry have had more than our fair share of this happening. I know that I have. Sometimes its the result of a previous operation such as wave soldering that was maybe a tad too hot which had loosened the adhesive holding the copper down. Maybe not so common nowadays with smd assembly techniques.
I agree. I had no idea what to do and assumed she would just ignore it. When she mentioned making a jumper it reminded me of a Louis Rossman video of making jumpers it clicked.
I'm so glad iFixit did this. I found iPad rehab a while back and I was extremely curious about the process. Knowing it was as intensive as this, it's great to see a nice in-depth coverage!
I'm glad that repair is making a resurgence. About 10 years ago I had some sort of electronic piece (I can't remember what it was), and no one was willing to fix it. It wasn't economics, it's just that it was during a period where absolutely no one repaired electronics unless they were a dealer for a manufacture. For instance, a few years before that I had a Pioneer AVR repaired by an actual authorized dealer. I had to drive almost an hour.
I really enjoyed this video. I've been soldering for 20 years as an amateur. Never micro though. I learned more here than in classes. Great video except for the joker up there talking over the expert and rushing her along. He really made me uncomfortable.
Thank you Jessa, amazing, and engaging. The importance of repairing is to push-back against a 'throw-away' mentality. Your skill and sharing it with us is appreciated. I wish to see more of the techniques and the skill demonstrated. Thank you from Liam in Sherwood Park, Alberta.
She really knows her stuff -- excellent video! If I may make one suggestion, using solder paste when dealing with tiny soldering tasks can be really, really awesome.
Jessa is awesome, I see why Louis rossmann is always mentioning her techniques, if Apple really cared they'd let her and Louis do their repairs in peace and maybe even employ them to diagnose their upcoming technology for potential issues!
it was? i thought he said "Cool to see a woman interested and being a master in doing this stuff." i don't see what's wrong with that statement. at all. the political correctness needs to stop, i prefer the truth.
In professional electronic settings, the overwhelming majority of workers are women. Fine, delicate, precise work. Guys handle the forklift, women handle the soldering iron. I'm rather skilled myself, but not as skilled as most of the "rework fairies" I worked with. Now, among my friends, the ones who solder as a hobby are all male. But again, Jessa is not a hobbyist, she's a pro, this is her work, and in this line of work, women are usually more skilled than men. It's easy to look at your comment and think you're stupid. I don't think so. I think your comment is stupid, and you're misinformed, and that's ok. Nobody can know everything. What's at play here is "implicit bias". We all have implicit biases, and that's ok, but just need to be aware of them.
Excellent series so far through episode 2. Looking forward to watching her do actual repairs. I certainly can't afford the camera and scope, but my OptiVisor setup takes me a long way. Biggest issue is my tremor, something Jessa obviously has yet to deal with but is a very real impediment for some of us, especially those of us over 60. So darned frustrating on regular soldering jobs; working microscopically would be impossible. I do agree, however, that my Hakko station and flux pen, copper braid, better solder, along with video presentations like this (mostly Ben Heck's) that changed my technique and understanding, have vastly improved my abilities, despite difficulties holding iron and solder on point. Kudos to all for saving me time, aggravation, and cash.
hafcanadian A We've had some people with tremor problems come through the Practical Board Repair course, and Louis Rossmann struggles with this as well despite his young age, but manages to make a living at microsoldering. When I am coaching folks with tremor problems, I advise them to grab the hot tip with a pair of regular tweezers near the tip of the iron. Using both hands will give you that precision control that you need. If you brace both forearms on the edge of the table, you'll see an amazing difference. You'll have to give up feeding the solder into the joint, which will offend all the purists, but you can make a fine practical joint by touching the tip to the solder and then transferring it to your joint if you're quick about it before the flux in the solder has a chance to burn off. Best of luck.
hafcanadian A Age has nothing to do with it. Just curse your way through it, I do every day, and find ways to deal with it. Once everyone is back from vacation I might do a video on how to solder when your hands don't listen to your brain, I have come up with a number of ways to get away with it. If I tried to do my job in a traditional way I would most certainly be working bagging vegetables at walgreens.
I've been using a Kester liquid flux pen for the past 2-3 months, and it works so much better for this type of soldering. It dries quickly, so not good with hot air or bga soldering, but so much better for any hand soldering. Really good for cleaning up pads with soldering braid too. I save the flux paste for where it's absolutely needed.
Exellent video on how to do soldering , i'm new on soldering but i already did galaxy s2 ac connector and samsung tablets also without microscope , not easy but i'm doing my best ! Thank you for this aweson video!!
Great video and series! I’ll add my two cents and say I disagree with a few of the commenters who criticized either Kyle of Jessa. I actually they were perfect together and very complementary to each other, adding up to a well-rounded and clear video. Jessa has a world of details and, explanations, anecdotes, and all that her experience has given and taught her. She could write books on all those, I’m sure, and if she were teaching a class over a school semester, you’d get a lot more of those stories, which far from being pointless digressions, are the humanizing thread that connects these odd ends of data, techniques and tips, and actually make them memorable. Kyle, on the other hand, is hosting the video for us. It *is* his job to kindly yet actively participate, pace the overall progression of the action taking place, and also - as someone learning as we are - doing these periodical mini summaries, as well as “translating”, with her help, into a language of someone who isn’t familiar with the process. Experts often lose that, since they’ve been long familiar with it, and speak among others who know the “lingo”, or simply to whom the basics are already implied and known. He does that proficiently and respectfully. Both do well what they’re there to do. There are plenty of experts who, unlike them, are the best in their field, yet not the best at teaching or showing. Anyone who’s been excited at taking a course with, say, this great renowned writer, who’s - lucky you - briefly a guest professor at your school - a unique opportunity since this person never does this... only to realize they’re not great at *teaching*... (this sounds specific because it is, lol it happened to me!) And well I’ll tell you, I still admire and respect the writer, and still took what I could from the opportunity to ask questions and the priviledge of the opportunity... And it also made me appreciate those who *know*, and *do*, and that so happen to also have the skills to pass that on to those learning. I think both Kyle AND Jessa can teach, show and explain. Without him, however, we might have a less concise and well paced video. Without her, well, him and us we’d have to read a textbook and look at pictures. And for those who felt uncomfortable or were embarrassed for either of them... don’t! You may be projecting. They seem perfectly comfortable in their interaction, and confident enough to speak for themselves were they to feel cut off or condescended to. I didn't see any of that, if anything they could be great friends (she knows his wife is a chef, so there’s at least *some* amount of friendly personal exchange going on there... Ok, I’ve done it again, and written a small dissertation on something that I’m sure I could’ve said in a few lines. End of wordy string of consciousness from me, everyone!
And yes, it does matter the temperature of the desolder iron. 1. The hotter the temperature for the average joe that is inexperienced will lift pads like crazy. 2. You only need a temperature that is close to the melting point of the solder itself. If you get it too hot you can damage the pads, the component, or the nearby components via ambient heat. Much care is needed on this level of soldering.
+C Crites Tip temperature is really the least important variable. Heat transfer is more affected by tip size, thermal mass of the particular joint, and the angle of the iron and placement of solder which will create more or less direct contact for heat transfer. Inexperienced people tend to use too little heat, which results in pulled pads. The most common mistake is a failure to recognize the differences in thermal mass on different pads in the same connector, so that the beginner will pull the connector too early when just a few of the pin/pad joints are liquid. Beginners would do well to crank up the heat and sacrifice the longevity of their tips!
I really enjoyed this, keep up the good work! I look forward to more. I started doing "basic repairs" on my stuff as well, I look forward to digging deeper thanks to you.
Overall a great video. I'm curious for the connector mount, why not use solder paste instead of tinning the pads? It seems like it would be easier to get the connector to set in place using paste that it would with the slightly rounded tinned pads. Of course, if you're mounting parts on a new bare board (vs. repair/re-work) paste is the clear winner.
Different methodologies I guess... I'm a big solder paste fan too, it's like cheat mode when soldering. However, I love seeing how this is done with regular solder as well... six to one half dozen to the other :)
I like the part where you talk about sanding the tip to meet the perfect shape and perfect flow. On one of my cheaper irons I like to go get some heavy gauge solid copper wire and use my dremmel to shape my own perfect soldering iron tip. I make hooked shaped thick, thin, needle, conical and chisel tips for f any size or bend or shape that my heart desires!! Awesome and cheap in a pinch or for a budget iron!
that helped with fixing my old mac (Mac IIsi) that i got as Not Working off of ebay. just replaced all the capacitors on it. finally got it to start up.
You can plate your tips with plating solution, I think chrome and nickel are popular. Way better than exposing core copper because that will just ruin your tips real quick.
Hi! My first time and I am already a subscriber ! A beautiful lady with an incredible professional background and a great personality with amazing knowledge and humble attitude. I have fo follow your Channel. !! Thank you for sharing !
+omsonic why not file the tip? It does shorten tip life, but from a practical standpoint, being able to deliver heat at the bitter end of a tip is a must for something as small as trace repair. These videos are all about Practical microsoldering for the purpose of extending the useful life of a device, not about microsoldering to conventional production standards. Brace yourself for when you see later that I'm mixing lead-free and leaded solder!!
Yeah, I don't think a 0.5mm chisel tip is going to be much help soldering 7 individual traces that all together are less than 0.5mm. I file a 0.1mm micropencil tip because 0.1mm is really too big for the job. You'll find that at 0.1mm, it is hard for even the best microtips to deliver heat right at the end of the tip.
If she really knew what she was doing, she'd be able to answer (rather than deflecting) his questions and work at the same time. You can tell the difference between people who are into things for money vs passion.
+Everett Jefferson Seems pretty clear she knows what she's doing. She gave plenty of explanation, and I can't think of any question she deflected. If her phones were failing after repair, you can bet they'd let her go rather than put her on their channel. What makes you think she doesn't know what she's doing?
ya wtf . i know a good number of people who are dedicated and some even prominent in their field, from machine learning to classics and linguistics, and those same people have nowhere near her patience, especially when working, and having read about many of my science heroes, very few of them appear to have had her patience. maybe fermi, in terms of questions, but i know this guy's lab etique would have thrown off fermi before a question was ever asked, plugging his files when she's explaining something hella interesting. and take about passion....fermi literally missed out on accidentally discovering beta decay 12 years before anyone else because, even repeating his gold leaf/radiation experiment hundreds or maybe even thousands of times consecutively, he never skipped any steps, no lapse in strict rigor. he also mentored somethin like a dozen nobel leaureates (next closest teacher in history was 2 nobel pupils i believe) and im sure they werent trying to sum up everything he said at a low level, at least not outloud. point being, your implication that shes unknowledgable in her field and in it for the money because of all of his reiterations and regurgitations of her output, or that she's not up to your standards because she isn't a perfect oracle of microsoldering that can perfectly solder and answers his nonquestions (which, by the way, she does do both of those things, the entire video) leads me to believe your assessment is based on something other than what you say, maybe deep-seeded misogyny ? idk, cus idk you, but the fuc u talkin bout b
Kyle, you shouldn't interrupt Jessa so much. Two people can't really talk at the same time and have the viewers completely understand everything. I understand that you are using questions and comments for our benefit, but let her finish talking before interjecting things. Just my opinion.
Yeah, his constant interruptions were very rude and awfully patronizing. Super cringey to watch him, this video would've been much better without his presence.
Just seeing this video for the first time in April 2019. Great Video, kinda learned something, do not know if actually have enough skill and fine dexterity to do this tiny level of park and soldering. All that equipment, too, looks mighty expensive and, also, what are the power requirements for those soldering and rework stations.
I have encountered a problem with second-hand iPhone 5s which dose not start-up,. it shows the iTunes. signal. When updates a message pops up stating, an unknown error occurred (9). Could you explain?. Tony
Jessa you alredy soldering that conector fpc with hot air gun? Works perfect for me... unfortunately i'm far, because I liked to have more formation and change ideas to evolve more.
I bought a cheap batch of iphone 5s, the screens are mainly broken and all are separated from their original circuits. To make the TouchID work with replacement screens, I have to match the screens/buttons with their original circuit boards. Is there a better way of achieving this than trial and error? I note the TouchID buttons each have a distinct 4-digit number (eg 1350) as well as the constant part number (821.2092) written on the ribbon and also that they have 2 QR codes on them (a concealed square black-on-white-paper one on the back of the circuit board and a rectangular white-on-metal one on the top of the plug). I had hoped that these would have some connection with the IMEI number or the serial-number code on the black label on the circuit board, but after decoding the QR codes, I don't see that yet. I haven't yet found anything on Google to help with this, does anyone know how to match up TouchID buttons with their circuit boards other than trial and error?
Maybe you can ask Jessa directly on her channel iPad Rehab or maybe she'll direct you somewhere you can ask. But i wouldn't keep my hopes up. If i was a device manufacturer, i'd simply take unflashed prelabeled parts from their respective bins, with these numbers on the buttons being merely to track where they came from in case there are issues, and if i cared, i would potentially store the matching keys in my internal database that Apple isn't going to expose to repairmen at the time of flashing the unit. But most likely, i wouldn't even store because i as a manufacturer have the means to reprogram these things. Relabeling things to signify that they match during manufacture is just such an unnecessary expense, as it introduces an extra work step.
also lead free solder joints have a shorter life time than joints made with classic 60/40 leaded solder (because the lead free ones are more brittle) and the lead free joints tend to grow microscopic oxide crystals (google tin pest)
Is this really the way to put a connector on the board. Even after reflowing the tinning, the bumps may not necessarily be even and soldering the pins individually from here will mean the connector wont eventually sit flat on the board? I would have thought that wicking after tinning would ensure the connector sits flush before soldering.
I see there are no other components on that board, but, on a component filled board, how do you avoid UN-soldering the components that need to remain soldered and adjacent to the work? Seems like the hot flux and heat gun would cause adjacent components to loosen and possibly be bumped out of the way.
What's your opinion on tip availability for Hexacon ThermOTrac Standard and Magnum gear I've scrounged over the years - I don't think these platforms have the ultimate small tips available (I think 1/64" is the smallest.) I do like the Magnum for caps on ground planes. What brand solder wicks? Some are terrible.
I tried doing that with my iPod touch... I lifted up the pad :( I lost all hope until I saw this! But I'm not sure what microscope to purchase in the UK? I hope they're not expensive but I doubt it
Never File a soldering iron tip it erodes the chromium and Iron plating that stops the tip oxidating and the the flux eating it away at high temperature, this can happen at an alarming rate as we have seen in industry when Lead free was first introduced, the chemicals would eat the protective coatings and tips were reduced in lifespan by a lot. Now we use flux enmbeded wire to clean the tips instead of water to reduce the oxidization and wear process.
I rilly enjoy this kind of staff and im very good in micro soldering but my problem is i dont have groups where we can share phone faults and how to solve them, can anyone invite me to any group
Instead of using a copper file, could you use a copper brush to transfer copper particles to the tip? (So long as full-copper brush, not copper-coated brush.)
I sanded an 0.8mm tip to 0.25mm to get in between components but the tip repelled the solder and the sanded tip turned black. Solder braid didn't help either. How did Jessa file her pencil tip and get more solder attraction to it? I didn't see any exposed copper which I think she mentioned being what made the tip more attracted to the solder.
If the tip is solid copper, filing/sanding can work. If it's made of something else solder repelling on the inside and solder-loving on the outside, this doesn't work. Copper Tips are basically sacrificial. Hot solder alloys with them and removes tip material each time you wipe. It's slow but if you solder a LOT or run the tips hot they can die quicker.
So I am torn between Hakko, JBC, and Weller.. I havent seen much on the Weller’s top of the line WX models. Does anyone have experience with the Weller WX series and if so what did you think?
27:35 Could a way to avoid the empirical path be: understand how to read the "whatever way the hot air company chose to calibrate de heat" works, choose a temperature, point it at a type of cheap thermostat and match the distance from the tip of the nozzle to the mercury (for this example) of the thermostat with the temperature needed to melt the solder? Sorry for the really long question :S
Hello everybody ,,Would you guys tell me what is the best heat gun that I can buy ? which once I should avoid ? and same questions goes to which heat sink I should buy ,Iam starting small biz for repairs ... thank you all.
We hear a lot from the media that businesses can not find skilled labor for whatever is the latest hot job in the market place.

The most common mistake is a failure to recognize the differences in thermal mass on different pads in the same connector, so that the beginner will pull the connector too early when just a few of the pin/pad joints are liquid. Beginners would do well to crank up the heat and sacrifice the longevity of their tips!
Great, I just repaired my Nokia 206 it was soaked, just changed lcd connector like on your video. Thanks
I really enjoyed this, keep up the good work! I look forward to more. I started doing "basic repairs" on my stuff as well, I look forward to digging deeper thanks to you.
Overall a great video. I'm curious for the connector mount, why not use solder paste instead of tinning the pads? It seems like it would be easier to get the connector to set in place using paste that it would with the slightly rounded tinned pads.
Of course, if you're mounting parts on a new bare board (vs. repair/re-work) paste is the clear winner.
Different methodologies I guess... I'm a big solder paste fan too, it's like cheat mode when soldering. However, I love seeing how this is done with regular solder as well... six to one half dozen to the other :)
Simply amazing video! Thanks Jessa for been an excellent teacher!
I like the part where you talk about sanding the tip to meet the perfect shape and perfect flow. On one of my cheaper irons I like to go get some heavy gauge solid copper wire and use my dremmel to shape my own perfect soldering iron tip. I make hooked shaped thick, thin, needle, conical and chisel tips for f any size or bend or shape that my heart desires!! Awesome and cheap in a pinch or for a budget iron!
could you give a list of the equipment used/profiled?
I have an Ipod Touch 6 battery to replace later (getting help with the soldering), so I'm just seeing what's involved. Interesting stuff, informative!
Wow. Really good video. Thanks for the great info.
that helped with fixing my old mac (Mac IIsi) that i got as Not Working off of ebay. just replaced all the capacitors on it. finally got it to start up.
I love your videos, you explain everything very well.
You can plate your tips with plating solution, I think chrome and nickel are popular. Way better than exposing core copper because that will just ruin your tips real quick.
Hi! My first time and I am already a subscriber ! A beautiful lady with an incredible professional background and a great personality with amazing knowledge and humble attitude. I have fo follow your Channel. !! Thank you for sharing !
Loving the videos Jessa!!! :)
Geelong MicroSoldering Hi ! I agree !I am just an amateur but I can see and hear “genius” on all she did on this one video!
awesome video, guys keep up guides like this.....
Great intro video for STEM micro soldering
+omsonic why not file the tip? It does shorten tip life, but from a practical standpoint, being able to deliver heat at the bitter end of a tip is a must for something as small as trace repair. These videos are all about Practical microsoldering for the purpose of extending the useful life of a device, not about microsoldering to conventional production standards. Brace yourself for when you see later that I'm mixing lead-free and leaded solder!!
iPad Rehab a .5mm chisel tip is a better option than filing the tip down to the copper...
Yeah, I don't think a 0.5mm chisel tip is going to be much help soldering 7 individual traces that all together are less than 0.5mm. I file a 0.1mm micropencil tip because 0.1mm is really too big for the job. You'll find that at 0.1mm, it is hard for even the best microtips to deliver heat right at the end of the tip.
There are wide tips available for the hot tweezers. They are great for removing an 8 pin opamp for example.
this video made me nervous, his constant need to interpret what shes doing, for us less intuitive watchers.
If she really knew what she was doing, she'd be able to answer (rather than deflecting) his questions and work at the same time. You can tell the difference between people who are into things for money vs passion.
+Everett Jefferson Seems pretty clear she knows what she's doing. She gave plenty of explanation, and I can't think of any question she deflected. If her phones were failing after repair, you can bet they'd let her go rather than put her on their channel.
What makes you think she doesn't know what she's doing?
ya wtf . i know a good number of people who are dedicated and some even prominent in their field, from machine learning to classics and linguistics, and those same people have nowhere near her patience, especially when working, and having read about many of my science heroes, very few of them appear to have had her patience. maybe fermi, in terms of questions, but i know this guy's lab etique would have thrown off fermi before a question was ever asked, plugging his files when she's explaining something hella interesting. and take about passion....fermi literally missed out on accidentally discovering beta decay 12 years before anyone else because, even repeating his gold leaf/radiation experiment hundreds or maybe even thousands of times consecutively, he never skipped any steps, no lapse in strict rigor. he also mentored somethin like a dozen nobel leaureates (next closest teacher in history was 2 nobel pupils i believe) and im sure they werent trying to sum up everything he said at a low level, at least not outloud. point being, your implication that shes unknowledgable in her field and in it for the money because of all of his reiterations and regurgitations of her output, or that she's not up to your standards because she isn't a perfect oracle of microsoldering that can perfectly solder and answers his nonquestions (which, by the way, she does do both of those things, the entire video) leads me to believe your assessment is based on something other than what you say, maybe deep-seeded misogyny ? idk, cus idk you, but the fuc u talkin bout b
are 0.01mm tips absolutely necessary for micro soldering, or can one get by with 0.2mm tips?
Jessa Jones knows her stuff .
This was terrific! Thank you for posting.
Very nice video, and good explained. I wish I could do micro soldering.
Kyle, you shouldn't interrupt Jessa so much. Two people can't really talk at the same time and have the viewers completely understand everything. I understand that you are using questions and comments for our benefit, but let her finish talking before interjecting things. Just my opinion.
Kyle is the host of the show, it's his duty to ask her questions. She needs to give him a chance to speak and respect his show.
Tbh she carries on forever I think he just wanted to sum up the ideas and move on to the next
Yeah, his constant interruptions were very rude and awfully patronizing. Super cringey to watch him, this video would've been much better without his presence.
Just seeing this video for the first time in April 2019.
Great Video, kinda learned something, do not know if actually have enough skill and fine dexterity to do this tiny level of park and soldering.
All that equipment, too, looks mighty expensive and, also, what are the power requirements for those soldering and rework stations.
Jessa Jones, the boss !!!!
Holycrap I'm excited to try this
I want to learn this so much thanks
So awesome! thank you ifxit, thank you jessa
21:49 knocks a pad off.....
The reason you can transfer the solder from the iron to the pads is because of the liquid flux being put on the board.
I have encountered a problem with second-hand iPhone 5s which dose not start-up,. it shows the iTunes. signal. When updates a message pops up stating, an unknown error occurred (9). Could you explain?. Tony
we used to bypass display IC and keypad IC etc by using only heat gun,soldering iron, magnifying glass, and some watch coil's as wires.
This guy is a real life version of that kid from The Polar Express
confused it with the Snowpiercer haha
I read this comment right before the logo passed and then saw him and understood exactly what you're talking about
AWESOME vídeo. Thank You very much for your time
Jessa you alredy soldering that conector fpc with hot air gun? Works perfect for me... unfortunately i'm far, because I liked to have more formation and change ideas to evolve more.
I bought a cheap batch of iphone 5s, the screens are mainly broken and all are separated from their original circuits. To make the TouchID work with replacement screens, I have to match the screens/buttons with their original circuit boards.
Is there a better way of achieving this than trial and error?
I note the TouchID buttons each have a distinct 4-digit number (eg 1350) as well as the constant part number (821.2092) written on the ribbon and also that they have 2 QR codes on them (a concealed square black-on-white-paper one on the back of the circuit board and a rectangular white-on-metal one on the top of the plug).
I had hoped that these would have some connection with the IMEI number or the serial-number code on the black label on the circuit board, but after decoding the QR codes, I don't see that yet.
I haven't yet found anything on Google to help with this, does anyone know how to match up TouchID buttons with their circuit boards other than trial and error?
Maybe you can ask Jessa directly on her channel iPad Rehab or maybe she'll direct you somewhere you can ask.
But i wouldn't keep my hopes up. If i was a device manufacturer, i'd simply take unflashed prelabeled parts from their respective bins, with these numbers on the buttons being merely to track where they came from in case there are issues, and if i cared, i would potentially store the matching keys in my internal database that Apple isn't going to expose to repairmen at the time of flashing the unit. But most likely, i wouldn't even store because i as a manufacturer have the means to reprogram these things. Relabeling things to signify that they match during manufacture is just such an unnecessary expense, as it introduces an extra work step.
also lead free solder joints have a shorter life time than joints made with classic 60/40 leaded solder (because the lead free ones are more brittle)
and the lead free joints tend to grow microscopic oxide crystals (google tin pest)
I have always been mystified by work like this... But now... Now I feel like I could actually do this !!! And then I woke up 🤣😂
Is this really the way to put a connector on the board. Even after reflowing the tinning, the bumps may not necessarily be even and soldering the pins individually from here will mean the connector wont eventually sit flat on the board? I would have thought that wicking after tinning would ensure the connector sits flush before soldering.
I see there are no other components on that board, but, on a component filled board, how do you avoid UN-soldering the components that need to remain soldered and adjacent to the work? Seems like the hot flux and heat gun would cause adjacent components to loosen and possibly be bumped out of the way.
Great video, very helpful. Thanks very much.
Awesome! I will translate it into Spanish in order to teach more and more people in my country
i like the spearmint flavor of microsolder
Hi, Where can we find the documentation of motherboards schematics (for iPhone, Samsung ...) ? Do know any trusted source ? Thanks
best video ever :D
thx i'm building a very nice lab and it will be my next investment!!
What's your opinion on tip availability for Hexacon ThermOTrac Standard and Magnum gear I've scrounged over the years - I don't think these platforms have the ultimate small tips available (I think 1/64" is the smallest.) I do like the Magnum for caps on ground planes.
What brand solder wicks? Some are terrible.
Why hating on that guy? He asked a lot of good questions
I tried doing that with my iPod touch... I lifted up the pad :( I lost all hope until I saw this! But I'm not sure what microscope to purchase in the UK? I hope they're not expensive but I doubt it
Never File a soldering iron tip it erodes the chromium and Iron plating that stops the tip oxidating and the the flux eating it away at high temperature, this can happen at an alarming rate as we have seen in industry when Lead free was first introduced, the chemicals would eat the protective coatings and tips were reduced in lifespan by a lot. Now we use flux enmbeded wire to clean the tips instead of water to reduce the oxidization and wear process.
Lower your iron heat a touch and use a preheater. Better flow and less chance of pulling a pad.
Really interesting thanks! What would be a ball park amateur entry level price for starting kit?
I rilly enjoy this kind of staff and im very good in micro soldering but my problem is i dont have groups where we can share phone faults and how to solve them, can anyone invite me to any group
Instead of using a copper file, could you use a copper brush to transfer copper particles to the tip? (So long as full-copper brush, not copper-coated brush.)
Jessa...how much do you charge to micro solder 3 pin connectors on a iPhone 6 and what is the turn around time? I live in Alabama. Thanks!
I sanded an 0.8mm tip to 0.25mm to get in between components but the tip repelled the solder and the sanded tip turned black. Solder braid didn't help either. How did Jessa file her pencil tip and get more solder attraction to it? I didn't see any exposed copper which I think she mentioned being what made the tip more attracted to the solder.
you filed away a protective layer and it oxidized. dont file this shit
If the tip is solid copper, filing/sanding can work. If it's made of something else solder repelling on the inside and solder-loving on the outside, this doesn't work. Copper Tips are basically sacrificial. Hot solder alloys with them and removes tip material each time you wipe. It's slow but if you solder a LOT or run the tips hot they can die quicker.
What is the model number of the microscope please ?
iPad Rehab thanks
www.amscope.com/microscopes.html?i_application=200&i_stand=1104
Great video!
So I am torn between Hakko, JBC, and Weller.. I havent seen much on the Weller’s top of the line WX models. Does anyone have experience with the Weller WX series and if so what did you think?
Highly instructive
Awesome video. Thanks a lot.
Very professional, I need to do. A list of equipment.....
This is like one of those cooking show commercials where they are advertising a certain pan or whatever but instead it's soldering.
27:35 Could a way to avoid the empirical path be: understand how to read the "whatever way the hot air company chose to calibrate de heat" works, choose a temperature, point it at a type of cheap thermostat and match the distance from the tip of the nozzle to the mercury (for this example) of the thermostat with the temperature needed to melt the solder?
Sorry for the really long question :S
What model microscope is that? Does it come with equipment to hook it to the monitor?
Hello everybody ,,Would you guys tell me what is the best heat gun that I can buy ? which once I should avoid ?
and same questions goes to which heat sink I should buy ,Iam starting small biz for repairs ...
thank you all.
My Sony motherboard digitizer connector has broken...is it possible to replace it..if it is...how to contact you...plzz reply
What's is this PCB holder called?? I can't find this anywhere.
21:44 Jessa Jones method, 21:50 Louis Rossmann method
She was using the wrong sort of tip to do it the Louis Rossmann way which is why she knocked that pad off...
Wouldn't solder paste make this a whole lot easier?
learned so much -thanks!
Jessa Jones is super cool.
Hi jessa do you teach micro soldering? and if so where could i find the information or get into contact with you or your organization?
How much for all that equipment and material?
