"I am not an expert. But over the years I have practiced a lot" This means the only difference between you and an expert is you don't do it for a living. Thank you for sharing your EXPERT knowledge!!
an expert would never slide nothing over the pins , except if at the end there are some shortened legs, you use air if you have the right hands or make the legs 1by1 or be super if you loose a pad.
except that everything looks just okay
No offense, but that's the difference between professsional and non-professional. You can be an expert on something and not make any money from it. Doing something professionally usually means you are able to make a living from what you're doing.

My most-needed, thorough, well-made tutorial ever!
I'm a 69-yr old EE & sw engineer and electronics enthusiast for over 60 years. SMD soldering passed me by because I was either doing software design or had hardware engineers who, when we architected PC-based systems, always contracted that out. When he occasionally had to change something, he took care of it. Then came STEM and semi-retirement and I got back into designing and building PCB based projects, and when needed, patenting designs. BIG problem - I never learned SMD soldering. I always claimed bad eyes and life was too short for that much frustration! I needed an AtoZ on SMD soldering. Your all-in-one-tutorial is simply perfect!
For example, I never bought separate flux, since one buys resin core solder anyway. 10 seconds of seeing how effective separate flux is for keeping solder in the right place, and the nice trick (which I will practice before soldering the 14-pin SOICs I plan to use), along with getting the right tweezers, soldering iron, and not goggle magnifiers but the screen version, has boosted this old engineer's confidence for the electronic equivalent of finally "learning to read" :-) Thank you very much! Instant subscriber.
Don't forget the microscope Andonstar AD208 (130$) !!!
Its actually really easy to do so. As technician from samsung smd line i can tell you when are smd boards repaired they dont really give a damn about how it looks , but its only for functionality , if it works then its good enough. Also when we repaired circuit boards we used only one soldering tip for all uses , it was flat small one.
Mitch... I am in the same boat as you it seems. I remember seeing the wave solder machines making boards and thought that was the end all. Now finding myself working on smd components to repair those boards! The most difficult part for me has been component identification. I need some better tools and some practice, but I am sure with video such as this one we can all gain some expertise.
In my 50s and though I am not doing SMD per se.. getting in to building drones which have some small pads and tiny wires to solder.. and my eyes are not at all what they used to be. Having the worse time even with a 7x magnifying led light. I also tried the Adonstar approach.. but it's too hard to figure out depth. Some people can do it. For me it did not work even on a 50" TV. I burnt myself a couple times. So I just ordered the AM binocular microscope. I am hoping this is it.. because there isn't anything else to get lol. The big thing I NEVER knew.. flux! I assumed flux core solder was all you needed. I have never seen any videos showing to use flux like the latest ones I see. I built keyboards for fun/hobby and none of the videos I saw of those which also have small components.. showed anyone applying flux. Just solder. Flux is a game changer.. I got a flux pen for now.. seems to work well enough but may try the flux gel (wax?) as well if that is better. I also just bought the micro pencil iron for my FX951.. hoping all this will finally let me work with the tiny soldering pads/wires. If not.. I give up.
@@b3owu1f i remember someone commenting: the rule with flux is there is never too much flux. All videos now show copious amounts of flux being used during all steps of the process.
this has to be the best I've seen yet. A heliarc welder for decades, My eyesight has degraded to the point that my right eye is basically worthless but for a bit of peripheral vision of 40% field of view.
I am convinced now after watching your video, I can use my microscope like yours, to level the field of view.
I'm excited to teach my one eye and hand eye co-ordination to function as well as someone learning to walk again.
Thank you so muvh for the Video.
Showing us what mistakes we can do while working with smd components was the best part of your tutorial.
Thank you
ten hours of Electronics class in minutes. great service.
this is the most thorough soldering instructional video I've ever seen. easily the most informative and instructional on this topic. THANK YOU!
I'm 40 and just learning electronics. This made SMT a lot more approachable. Thanks for the quality video and taking a lot of mystery out of it for me.
same. 41, was fired from my job. Decided a career change. Just starting to learn electronics as my goal is to become a computer repair technician. Just curious, why are you learning and how far are you in your journey?
me too is it something to do with turning 40 😅 always liked tinkering but never thought of it as career... became a chef instead 😂
@@philmckrackin1683 Haa I just hit 50 and been in desktop support most of my career. Now learning electronic repair soldering. Good luck to all you guys
First learned to solder back in around 1990 when I was in college and we had a basic electronics class.
Been 'winging' it on and off over the years when I needed to do some soldering over the years. And now I realize there's so much more to it; I was missing tools and techniques and, at best, have been doing it inefficiently. Been thinking of taking a course again and this was pretty interesting to watch.
My soldering history starts in early-mid 80's. The Michael Jackson hay days 🙂
@@RingZero mine started in the late 1960s as a high school student "fixing TVs" and taking a n electronics course building a tube amplifier. Things have changed a bit. This was an excellent tutorial.
Taught myself how to solder back in the mid 2000s as a young teenager. Needless to say I for years was HORRIBLE at soldering. didn't know about tinning the tip, didn't know about flux, anything. Wasn't until about a decade later, late in college when I learned a little more, slowly but surely. Unfortunately for my skills, everything has gone SMD and my knowledge and skills still haven't caught up. Finally, a little over 20 years later my knowledge and skills are about caught up, and I just had a digital camera for SMD soldering get delivered. I should finally be able to get so small SMD soldering done with acceptable quality. Thanks for this solder summary.
im the only one how find this super relaxing? great video!
I think it should be mentioned that isopropyl alcohol is just a solvent. So it will dilute the flux residue, but the residue is just spread all over within the solvent. If you let it dry, the flux is now a big sticky smudge everywhere. This is why you need to use paper tissue ( Like Kimtech Wipes) to absorb the alcohol containing the diluted flux residue. Once dry, you ll see that your pcb is neat and clean and your wipe is yellowish/brown (if using rosin flux. "No clean" fluxes won't). Q-tips like in this video will do, but not as efficient
If you want boards that are actually clean you need to rinse the board with fresh alcohol, not just blot up the worst of the mess.
I routinely used a three bath process. The first bath was to remove most of the flux. The second was to finish the job. The third was fresh alcohol to remove the last of the residue. Once bath 2 became too contaminated the alcohol was moved to bath1, 3 to 2.
My very strong perference unless something prohibits it is to use solder with water soluble flux. The flux absolutely must be removed within a few hours because it is corrosive and conductive. It can readily be removed with warm water. I used compressed air blow-off at a couple of points becaue surface tension tends to cause contaminated water to be trapped under parts. After a final blow-off a rinse with distilled water is appropriate.
Perfect. You forgot the last step. After cleaning the excessive water with compressed air we let the PCB to dry in a dryer. 👍👍👍
I find coffee filters work better than paper towels too since they dont leave behind fibers like paper towels do.
This worked an absolute treat. At first I tried to individually solder the pads of a SOP30 op amp. Didn’t go well, then I watched this video and tried using this technique, but still using my finest soldering tip. The second I changed to a large chisel top it all fell in place and now it is beautifully soldered and soo easy 😁
Tip size is very important for heat transfer.. The right tip for the job
I had no clue how to solder and wanted to install an MM3 chip to my Playstation. This video actually showed what I'll need to do the job and the technique I'll need to use to accomplish the task. This video is a wealth of information! Thank you very much!
I'm so glad I clicked on this video. This was really helpful. I also realized that investing in high quality soldering materials is a must. I just finished my PCB a while ago and learning from this video saved so much of my time. Well done! Thank you, sooo much.
Absolutely perfect tutorial. I'm getting ready to solder a connector that pulled off cleanly from a robot vacuum. I feel confident that I can do this with this tutorial.
Thank you for a very informative tutorial! I particularly like how you show some errors, which are essential for good instruction but often forgotten by instructors.
“Then using a metal or plastic spatula, we drag the paste so it will spread evenly” BRO YOU’RE USING A PCB 😭 that’s finesse to a whole new level
I have been doing some SMD projects for a few months, and your tips are really great. Thank you. I probably will watch this video a couple of times just to remind me of the tricks.
Feel like an idiot. I have a hot air station and never thought of adjusting the air flow!!!
By clicking this video my 22:49 min haven't gone waste it so much worth it you deserve more sir keep going so much effort and so much information .Good day ahead 🎉
Havent touched a soldering iron in 30 years. Got my confidence now. Thanks.
Ever soldered SMD components with a hot plate?
Same process with the stencil, placed all the components, and placed the pcb for short time on a hot cookingplate, stay sharp and alert, remove as soon as possible when everything is soldered.
worked like a charm.
Absolutely brilliant tutorial. I am very much an amateur and still quite a newbie but I’ve found a few things that helped me. The first isn’t rushing, heat the pad for a second or two first and don’t be shy with the flux. What I do with the tips I use most often, pencil, hoof, conical and knife is to have them all set up in their own cannula. Then I don’t have to fight with a hot tip and can just unscrew the cooler plastic part to change them. If you can’t afford a top quality station, or like me you’re an amateur, you can still use better quality tips, such as the Hakko T18 series. They are more expensive as one tip is the same cost as a set of a dozen cheap ones but the difference, along with using a good solder, is phenomenal. Over time the tips work out about the same cost because they last so much longer before pitting and you use all the ones you order. Those £2.50 soldering kits off eBay are worth every penny, being a sad sort of person I’ve kept mine and can see my improvements over time.
For the last few weeks I learning how to use a YIHUA 853D hot air rework station I recently purchased. I enjoy the challenge of it even when I blow a 0805 resistor into the next room and can't find it. I got one of the Gikfun learn to solder kits. I have not started on the 0603 or 0402 packaged components yet. My 51 year old eyes are challenged enough at 0805.
I went to school for electronics and learn solder back in late 2000s, and Im just now hopefully getting a job where I would be doing a lot of soldering. This is a good review video.
I was searching for that type of basic video to clear my doubts. There is no other video which include this type of basic and proper steps. Thanks for making such type of video
Do note that he makes plenty of mistakes so you should also look how other people do it
He adds too little flux (flux is your friend always)
He heats the pads without solder on the iron so the temperature transfer is poor
He also didnt heat up the sot23 pads enough
This is the most clear and complete video that I saw about soldering.
Big thank you, is amazing!
It's a good video, but if you really want to go in depth, then watch the 'PACE soldering tutorial' 👍
What a mastery! I used to think of the SMD soldering as 'taboo', but thanks to your tutorial I was able to fix my monitor (a burned step-down converter, 8 pin SOP); of course my work was much messier from what you show on your video, I've even managed to de-solder a couple of neigbouring parts... but it will get better with practice! 🙂

Pero que flojera, sera que un gringo siente lo mismo al escuchar un vídeo tan precioso en español, un fuerte abrazooooo hermano querido, gracias por tu insuperable aporte de valor real.
I just got a set of tools now I know more techniques to try I'm going to build those Christmas Tree PCB boards for presents this year I will learn as I go.
Thank you for actually putting working links in description can't tell ya how many UA-camrs fail at doing that.
I ordered almost everything on the list as I got a few cpus to fix with broken pins.
One of the best soldering videos on UA-cam
pro tip: before continuing with the rest of the pads at 12:30, make sure to press on the chip with the tweezers and heat the first and only pad you soldered. move away the iron and keep pressing until the solder has solidified again and then stop pressing the chip. this ensures that the chip sits flat
Thats the best resolution and depth perception together with magnification i have ever seen in youtube videos for rework....tks
thank you! you made it very simple
every other guide didnt make sense because they never explain why to use certain items like flux, they just say "use flux"
So far..this is the best soldering tutorial i ever watched... 👍👍👍
I'm putting a lot of thought into this because I really liked the video. As an IPC trainer, there were some things I liked and some I didn't.
Things I liked:
Recommending a soldering iron with temp control.
Reminding proper storage and checking the expiration on solder paste.
Recommending use of flux. (Many put too much trust in the solder's flux core)
Explanation of component size designators, like 1206.
Reminder to check component polarity.
Tacking opposite corner leads on a DIP. (Also skipping leads to prevent overheating one area)
Nice suggestions for hot air guns. (The solder paste portion was probably the best part of the video IMO)
Things that could be improved:
An overemphasis on shininess, whereas fillet shape and wetting is more important.
1:29 Cutting against the edge of your boards, risking edge depanelization.
2:12 Using a tip that overhangs your pad (which also looks oxidized and left FOD)
3:23 Saying you should have "the best quality" solder. This depends entirely on the assembly.
3:28 Saying thinner is better for SMT. Depends on the pad/lead sizes. Too thin, and you could underfeed your solder or unnecessarily increase dwell time with the iron.
4:06 Saying the flux keeps the solder on the pads. This is what solder mask on the PCB substrate is for. Flux is for cleaning away oxidation and comtaminants and also assists with heat transfer.
7:40 Not adding flux when tacking your component. The flux in your solder was completely burned away and you may not get good wetting.
7:56 Not adding flux for solder reflow. Also, every application of heat can increase the thickness of the intermetalic and cause embrittlement.
9:34 Recommending solder wick to remove excess from SMT. If someone is struggling to feed solder properly, they may also remove too much with solder wick. Repeated addition and removal will lead to damage.
16:44 Holding your iron directly against your component. Better to use a chisel tip for that.
17:20 Pressing down on a DPAK. Pressing down can thin out the thermal plane connection. A thick base connection is always better. Your thermal plane also looked like it didn't wet properly, probably because the flux burned off.
Hands down best video on soldering. GREAT INFO and step-by-step instruction.
It was the best video which taught me something new and pointed me my previous mistakes that I was doing years long....
I could never solder SMD on a PCB before, until I bought a freaking microscope. Now it is easy peasy.
Yoo this was very useful. I haven't done it in 5 years and just watching you work brought it all back
Hello from Turkey. Thank you for this valuable information you give to amateurs like us.
I personally think your an expert and your Very professional.
Longitude is the measurement east or west of the prime meridian(7:02). In English we use length to describe a dimension along with width.
Nice informative video.
Kiitos! 🙂
Working with PCB:s 50+ years and now learning to make perfect SMDs today at home (Now retired)
Wow one of the best if not the best how to videos I have watched. Liked and subscribed
Excellent tutorial. Thanks to You, I managed to replace a component in TSSOP-16 package with my very primitive tools! Thanks again👍
You make it look so easy.. I'm fairly certain that I've said never before heard curse words when I tried my hands on soldering. But having seen this video, I know what I did wrong back then. Thanks for this
Solder paste, flux is really magical!! 😅 it makes your work damm professional
Thank you. I am going to attempt a repair of a surface mount PCB and this tutorial is exactly what I needed.
I learned a lot! Many thanks! I'm collecting car stereos and from time to time they need some soldering, a real challenge if you do not know the basics
One of the practical videos I saw, specially the brief explanation about tip sizes.
Such a great video. You explained each and everything perfectly that even a noob will understand. Lots of love from Nepal.
Finally managed to solder a capacitor after many tries thanks to this tutorial. Congratulations for the amazing content and thank you very much!
Que cautin usas?
@@davidhernandezjaime4821 JCD 8898. Very cheap and worth the price
That was excellent. The important thing is the connection not that every connection looks exactly alike. Thank you.
The thing i think is so cool is the use of the more inexpensive cameras to view through. Years ago they would use a science scope ,a microscope with a long focal range so you had room to work. They cost in the thousands.
thanks, your pronunciation is so very clear
one of the most useful videos i ever seen in youtube about soldering thanks a lot
Great tutorial, loved the magnetic PCB holder, I didn't know those existed.
7:32 i like your video very much. Significant different to others is your solder tip touching the solder pad, heat up the pad then put the solder wire to the solder pad. I think this is the most critical technique to get a good shape solder joint. anyway i still found some of your demo solder joint have excess / not enough solder. frequent tip cleaning is very important.
I just need to solder a volume pot for my guitar but after this video I think I'm ready to solder a new motherboard for my computer. But first might be helpful to get a solder machine 😅
Thanks very much!
Excellent tutorial. Exactly what I need, before taking on my 1st project populating an SMD PCB. Newbie mistake #1, ordered Polyimide Film 3mil (0.003") stencil, instead of stainless steel. The polyimide is too thin (not enough solder, I think) and it was deformed during mfr. So there's like a bubble, which will allow solder to flow underneath. 😢 Perhaps I can skip that area with the spreader and use the syringe after removing the stencil, instead. Wish me luck, Folks. I'm gonna need all I can get.😎
I was deeply amused to see you using a circuitboard as a squeegee for the solder paste!
I watched another video right before this that used a different technique on the ICs while mentioning the drag-the-tip-across-all-the-pins method, while also mentioning that the flux helps ensure the solder only goes where the metal contacts and pins are.
Before these last two videos, I had thought with my severe lack of coordination and steady hand that the smaller SMD components were out of manual reach, but between the first video mentioning best to get .2mm solder and showing that technique, while also seeing the rapid tip-dragging, weirdly, it makes it appear *easier* than dealing with through-hole soldering, which I last soldered in the early 90s.
Thanks for this video!
Very good. I thought keeping a steady hand was hard for welding but this is taking it up a notch. I'm almost afraid I'd inhale one of those parts
By doing smd soldering i can observe that you are avoiding contact with pins, just touching the pads with soldering. May be some contact, but i find this tutorial useful. Thank you and one like from me. 👍
With the apparent, upcoming influx of desktop EDM machines, the soldering flux template you use at the end, could be custom made from home, so it becomes possible to design own PCBs and make flux templates for them. Thanks for a great tutorial btw. I've only seen how this is applied in timelapse version, so I've been utterly confused as to what flux to buy and how to properly use it. This makes all of that clear
Very good soldering tutorial. We are glad that you are happy with our PCB's 🙂
After watch this video. I'm become your a subscriber. From Kuwait.
I must admit, your video was very good. You gave us all great examples of how to solder a lot of different types of SMD components. When it comes to your soldering, keep practicing on your end results. Some of the soldering you did was acceptable, but still could use some finishing touch ups. You didn't do anything wrong or bad. I am only talking about the end results on some of your work. Like some of the solder joints are not snooth. It should not have and peeks or valley's, and no blobs anywhere. Also be sure that you do remove any and all solder balls like you did do, so good on you for doing that.
All in all, it was a great video and I look forward to seeing you progress further with your projects and solderings skills. Keep up the great work and video's.
Nice to see, also good explanation for people who (try) to repair everything. Special 2-way communication equipment. Just for hobby when i have free time. I see that i just missed solder paste, i will try to order that one and ofcourse a good heatgun (not for remove paint, hi). Thanks again and i will click on the thumbs up button !
Excellent and interesting explaition thank you so much for sharing this wonderful and amazing video
Wow very not time wasting and very noob friendly I have been looking for this information for many years
Thanks for the video. It shows how to solder SMDs using a soldering iron, using the appropriate tip for this type of work.
thank you electronoobs please produce more videos like this it helps me alot wondering specially on a tight budget like me in prototyping
Excellent video! Been in the electronics field a long time. Started back in the mid 70’s with vacuum tubes. Times are changing and to be successful you have to change with the technology so thank you for such an excellent video presentation of smd devices and proper technique in soldering with the use of soldering iron and hot air. Been looking for a through presentation such as this. As I progressed from the old linear power supplies to switch mode power supplies some of the earlier simp utilized very small surface mounted controller chips on double sided pc boards where the controller chip were surfaced mounted on the opposite side. Replacement definitely required a microscope and excellent surface mount soldering skills. Either that or purchase new smp board which I preferred since I had none of the specialized equipment needed. Thanks to your video I will be investing in the digital microscope and the additional supplies. Keep up the good work as I am trying to understand surface mount devices with the numerous standards of identification.
I wanna see this guy to solder vacuum tubs.
Awesome video 🔥 Best SMD soldering tutorial I've seen yet great job.
Díky!
Great tutorial, I would recommend to not keep the soldering iron tip heating or applying soldering to the pad for too much time, as the pad can come off (lift) from the board, nor when soldering the component, as it can break due to too much time exposed to heat.
Considering a shape of a melted solder, I'd suggest that the temperature was quite low.
Or the solder was not "the best" (with a cheap core).
i didnt know until i finished this video that this was an amazing video .. this helped me a lot with my work
This was extremely helpful and one of the better soldering tutorials I have seen. Thank you!
Thank you for this video, i just watch like multiple other videos about this but this is the only video that answered all my questions. Very informative
The best soldering tutorial I have ever seen !
Very well and clear explanations of the soldering tools required for beginners. Great !
Great video. Love from India. Learnt something new today.
You are the best bro :)
Sam 🎵✌🏻
A wonderful tutorial! Yes, I was always hesitant to try and solder anything other than a prototype board. Even that u struggled and I see why now. I did not use Flux ND the proper tips. Thank you, I now feel like I can try creating my own pcbs and soldering small components
Great video,very informative. After many failures I found using a solder flood method on the pins then the wick to remove excess solder worked for me for many years,finally with a torch on the opposite side of the pcd i could easily check for shorts and correct as necessary.
this is such a great video. explanations are thorough and very easy to understand. just watched it again! thank you very much.
You are the best! Your videos are sooo easy to follow and understand. Thank you immensely!
Best tutorial I've seen so far!
Very good video, helped me reattach a SMD resistor that fell off my PCB!
I'm a J-STD certified technician and this video was still great for picking up little tips and refreshing technique on some less-common components we work on.Thanks.
AMAZING tutorial and craftmanship. Thank you for video and great attention to detail. 10/10
thank you my good man, I was finally able to properly solder SMD components!
I like ur tutorials that every day I have to download like 5
indeed, i have lost the fear. cannot thank you enough for this video!
PERFECT..NO WORDS...!!!..TO THE LAST DETAIL...!!
Thanks for the tutorial! Lots of great information and ideas that I can use to help set up my SMD soldering workstation!
You should always have solder on your iron when heating the pad, it will transfer heat better
correct. and always keep the tip clean.
Also Soldering temperature too low.
Also, there's no such thing as too much flux until it forms a sticky mess.
Also, drink Dr. Pepper.
@@tazman4855what temperature is good?
Those hands are steady as a rock. 😮
Really good !! Thanks very much ! No more SMD soldering fear ! :) maybe i'll try.
