Buy a Tristar IC with same day shipping from NYC! store.rossmanngroup.com/index.php/ics-components-and-chipsets/components-by-type/charging-circuit-components/tristar.html
hello jessa excellent video very detailed and precise, I have the same problem on the ipad that I am repairing it does not turn on and does not load on the doc connector of the card the resistances to the mass they are not precise evaluating the scheme should be the tristar. What do you think about it?
Nice work! doing the same repair today... some pulled pad like this.. Usually i use green oil to hold the jumper.. Now waiting UV box to cure it quick and watching ur video.
Thanks for a great video? Do you think this can be done at home with hairdryer, solder tin and solder? My phone is 'reverse' charging. And or not taking charge at all. Regardless of MFI cable or not. Thanks for every and any insight.
I hadn't thought of putting the tweezers in the ultrasonic. I'll do that when I get to work in the morning. I've gotten to where I store my tweezers in one of those wire/flux pad things to clean a soldering iron with. I don't have to chase to find the tweezers and jabbing them in that cleans off the yuck that accumulates on them.
Thank you for the video. Please tell us - what model is a mini hot-air soldering station. I have a Quick-861DW. It's a beautiful station. BUT I want to buy another Quick-860AD .. This is essentially a clone of Metcal HCT2-120, but not so expensive ..
I realise you might not read this Q as its an older video , but I am left a bit confused regarding where you ran those two jumper to , as the second one could not be seen and the first one you soldered to where the shield used to be , but would that not create a short to ground ( or did you cut them both off when the chip was fixed down ) only it was not to clear to me , I would really love for you to clear up my misunderstanding ....kindest regards Jessa your the best most patient and gracious teacher ever 🙏
hi thank you for your so nices videos. I am so fascinated by your skills... I know you use a Hakko iron and JBC hot hair pencil. But what is the brand of the microscope you use please?
Most repairs use AM Scope. They use trinocular scope to use the camera to post on youtube and online sites as a marketing tool. It is your choice to use any microscope that is suitable with your budget. At least use stereo zoom microscope. Do not use the magnifire like things that cost about $200.
Oh man I think you missed a bit I was really looking forward to knowing, maybe you mentioned it but I keep missing it, what do you do if one side of the ic is black including the pad it solders on to?
I've never seen that on an ic, but burned filters sure. If there was so much heat during a short to ground of a high voltage line then the component will weld, not solder, but weld as in molecularly join to the pad. It can't be separated from the pad, so in that case the of will come off with the component and you work with the trace that's left behind.
+iPad Rehab yeah you're right, my bad, I meant a filter, if a filter is corroded on one side, including the pad, do I make a jumper from the other side of the filter or do I replace it with a filter? Also how do I find out where to jump it to if it isn't obvious? Thank you very much for your time and that nugget of info and I enjoy your videos loads and hope to hear from you soon
Hi, I love your videos and find them really helpful please keep up the good work :) one question I have when it comes to soldering jumpers on SMC's is would it be easier to solder the jumper to the chip rather than put it in place on the board, it won't be practical with pads towards the middle but on the outer edges I wondered if it would make it that bit quicker and easier? I'm sure I'm overlooking something, thank you again for the great videos :)
+Daniel Jefferies I don't understand how this would work conceptually. Starting with a pre-balled new chip, the act of putting a jumper on the chip would destroy the ball. Let's say you were reballing a chip, then in theory you could seat a jumper within the new ball---but then how would you ensure that the jumper also soldered to the underlying trace on the board that is adjacent to the ball? It would be a nightmare to do it this way.
Nice work and a nice working place. Have you tried to flatten the end of the wire where the ball sits? Greater surface to attach and low profile. Sorry to say this, but you should work like a watchmaker, in the same position because you can develop spinal problem.. like me.
I'm in need to buy a super tiny soldering iron, what brand/model would you recommend ? I need a better one to solder 0402/1005 components than the one i'm using actually. Thanks a bunch for your reply, love your videos! :)
Thanks a bunch... Oh and btw the equipment you use is 10% of my interest in your videos, rest is driven by your talent and super clear explanations... Everything seems soo easy (while it's not)
could a new pad be constructed by setting the shape of a new track in small copper wire and then striking the end on a hard surface with a hammer to create a new pad.
Iv'e come across a few chips that are covered in potting compound and no matter how hard I try I cant remove these without lifting pads, do you have any videos that cover those chips that are potted?
In regard to error 27...This may sound counter intuitive obviously but with error 27 if the issue was space being filled up by error logs and not actually corrupted software... in theory would pulling the nand and essentially copy and pasting the data to a bigger size nand work? Lmk ur thought. would love to hear from ya even though this method if it would would be xtra.
The NAND would not match the data about the NAND. If you actually swapped a nand for a different NAND and copied the data about the NAND then the device would boot to DFU and prompt you to restore. It can work, but not for data recovery, only NAND expansion
Hi, it has nothing to do with your video, but do you have one of this NAND programming devices, Chinese use to turn a cheap 16GB Phone into a 128GB or to unlock iCloud? Or to fix NAND Problems.
Tremendous work as usual and a little luck. Hate bga traces but when it works :o) have you used the jbc nano tweezers jessa well worth the upgrade from the hakko tweezers.
+Jessa Jones hmmmmmmm shocked bad station or offsets wrong ? mine were accurate out of the box a friend his machine, was on an old firmware and out by 220f bug in firmware ? updating firmware fixed it without adjusting the offset to get a good thermocouple reading. it h/eats up ground connections for breakfast to say it's a nano machine shame you had problems with yours. Don't know if you know how to test u2 ic, pretty quick when you have no power and and no charge even with good known battery, if tristar bypass cap, is grounded the ic has a protect mode that can be reset :) will be the only cap on board that's shorted it's the safety mech it's programmed to do that can be reset via jtag interface.
Hey Rehab. i tried to install the software you are using "zxw" tool . and when i get it down on my computer it is on china. anyway when i try to install it ,, it says that it missing files.. and i did google the software alot and it is the same coming up. Do you have a link which the software works ?
Learn to be more careful. Seriously, there is no reason to pull pads. You should be practicing on scrap boards until proficient, then you will never pull a pad on a device that you're actually intending to fix.
What about if say it was on the board you had to repair, like this one. Would that be considered unrepairable since you'll be touching other pads? I'm just curious because I want to do this stuff, but have always wondered about those situations. Btw love your videos, I can binge watch you and louis' videos. Keep up the great work! :)
Hello Beautiful lady. I am worried about you in Azerbaijan. Flux is used by removing the chips, boards do you use ?. I'd like to come to you, and you learn a lot of things.
B4 is D_PAIR2_N *on the ipad mini 2* (If you tell me what device you are using since the function varies on the device, I can tell you to what it connects)
B4 is connected to 90_TRISTAR_BI_E75_PAIR2_CONN_N That connects to pin 30 on J1817. Just put a wire on the missing pad. keep it in place with some kapton and solder a new one on.
If you've got a missing pad then you don't have any copper anymore. Look if there is a via that connects to that pad. If not Run a wire under there. Look at Jessa's video she does a great job at explaining it.

I couldn't believe phone repairs can be so hilarious! Excellent video about the repair and conversation! Haha! You are the best!!
I'm such a fan of your work! I learn something every video.
Nice job Jessa🧸 I love the dream team you and Sunday are so awesome to listen to and nice to look at too😘 uz do great work.
there is nothing in the world I love like some good hard work.
Watching it, not doing it, that is.
Your stories are so funny!! Great video

+Lai KL green oil--interesting. I love hearing the innovations that others use to solve the same problem :)
Thanks for a great video?

Thanks for every and any insight.
Hi, saw you with Louis and enjoyed watching you work, subscribed :)
"We can inspect our balls, let's look at some balls!" lmao

Ah i love you guys, fun and entertaining!

i cut them at the end--they were just left long to help keep the actual jumper in place while soldering the new chip down.
Thanks Jessa much appreciated clearing that up for me , and taking time out of you busy day to answer me 🙏
hi thank you for your so nices videos. I am so fascinated by your skills...

She doesn't ever answer anything related to the way she fixes or the tools she uses. As she thinks she's the only micro solderer in the world lol
thnx rehab for teaching us
Great video, would you like to know which stream you use?
Oh man I think you missed a bit I was really looking forward to knowing, maybe you mentioned it but I keep missing it, what do you do if one side of the ic is black including the pad it solders on to?

Thank you very much for your time and that nugget of info and I enjoy your videos loads and hope to hear from you soon
+krayzeeali if the pad is gone you can't connect anything to it, and you will have to find schematics or pathways to find where you have to jump to

What equipment and things do you use to complete a U2 IC replacement?
Thank you so much! Have you got any tips for a beginner hoping to reach your level or expertise in the repairing phones field?:)
just learn your signature problems and start fixing, one phone at a time
Thank you so much, you're a huge help seriously.
I've looked through some of your videos and was just curious as to what 'flux' you use? Thanks in advance.
Tremendous work as usual and a little luck.
Hate bga traces but when it works :o) have you used the jbc nano tweezers jessa well worth the upgrade from the hakko tweezers.
Yes, I sold them. Too tiny and not enough heat transfer. Love my fm 2023!

Do you have a link which the software works ?
I live in Chicago and I'm considering opening a shop and repairing full time. Do you offer training?
We run a 5 day training course in board repair and microsoldering once a month. Details at www.mendonipadrehab.com
Have you gotten any Apple Watches in for screen repair?
What can you do if the ripped pad was on the center? Just curious.

that wire uses?
Bonsoir
A combien de degrés chauffez-vous la puce s'il vous plait?
Merci
Please
Tell Sam it's the banker that gets to do that ;)
Yeap! One of da best!
I can know the type of flux it uses. Thank you

Pulled pads are only a problem when you've put the glue side up.
that model hot air station used
+damian4522 jbc jt-a is my station of choice
So true "if you don't have a sense of hummer , it's just not funny" how about " The Board Ladies of the Big Apple "
Or the (Bad Apple)😆
please help me!! is the B4 pad connected to something??
B4 is D_PAIR2_N *on the ipad mini 2* (If you tell me what device you are using since the function varies on the device, I can tell you to what it connects)
Im using an iphone 6 plus. I broken that pad and I don't know how to save it. Please help me.
B4 is connected to 90_TRISTAR_BI_E75_PAIR2_CONN_N
That connects to pin 30 on J1817. Just put a wire on the missing pad. keep it in place with some kapton and solder a new one on.
You are amazing! But if i got the missing pad where do i connect the wire? Do i have to scratch under the pad until find the trace?
If you've got a missing pad then you don't have any copper anymore. Look if there is a via that connects to that pad. If not Run a wire under there. Look at Jessa's video she does a great job at explaining it.
Hello how are you , how could I get apology diagrams or if you sell me iphones only , please. Thank you.
and if I could write to mail or give me yours to contact us, to help me thanks .
você é de mais !
how could sign up to have a classroom course currently ..... jessa a contact number of school ::::
Madam How can I communicate with you
Send a message to my website for business inquiries. For "hey bro plz help me with my problem, plzzzz" submit your question to a forum.
Good video but too many distracting side talk !!!
...less yackety, more soldery...
kkkkkkkkk
