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.
Showing us what mistakes we can do while working with smd components was the best part of your tutorial. Thank you
im the only one how find this super relaxing? great video!
ten hours of Electronics class in minutes. great service.
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.
I have seen hundreds of videos about doing repairs and adding components, but this is the best so far. Have purchased almost completly set of repair system and are going too be trying at 19th because then i have getting everything i need after i had alot of bad experiences with repairs shops that couldn't figure out the issues and didn't wan't too try too fix them either and i was wasting alot of time and money by sending the bad PS5's too other repair shops. I get that some issues can't be fixed. But some are, but i feelt many of them i had experience with was bad. So after i have seen more or less hundreds videos (mainly focused at PS5) i have too say that this video has been the video i have learned most by doing this things. I have learned alot how too diagnoes the PS5 with those videos, but this is what i exactly needed too begin with before i am actually too add the BIOS chips on the PS5 and other components. I'm kinda nervous for the BIOS chip (i had too remove the previous one because i manage too damage it when i was removing it. Was going too be manipulate it from disc too digital version, but got damages. It's the first time so that could be happending. But i'm glad you are sharing your many years of experiences and explain it why you are doing the things you are doing so we the beginners understand the reasons for the things we are doing and i can't wait too see the results at 19th when i'm getting the chip i need. Had some interested in this last year now and hopefully i could be doing this as a side hustle.
Havent touched a soldering iron in 30 years. Got my confidence now. Thanks.
"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!!
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
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!
So far..this is the best soldering tutorial i ever watched... 👍👍👍
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.
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
One of the best soldering videos on KZhead
Great tutorial, loved the magnetic PCB holder, I didn't know those existed.
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 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.
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 KZheadrs fail at doing that. I ordered almost everything on the list as I got a few cpus to fix with broken pins.
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' 👍
Hands down best video on soldering. GREAT INFO and step-by-step instruction.
this is the most thorough soldering instructional video I've ever seen. easily the most informative and instructional on this topic. THANK YOU!
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
Hello from Turkey. Thank you for this valuable information you give to amateurs like us.
THE BEST VIDEO tutorial for SMD soldering - from and old git solderer learning new tricks - UK
Excellent! Very comprehensive. Thank you for sharing all the different techniques.
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
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.
This video was done very well. Very helpful. I've dont THD soldering for a very long time but I only do SMD on occasion for repairs or when I can't get a component in a through hole package due to it being discontinued. But I'd like to do more SMD work since SMD is the future and theres less and less THD components each year due to discontinuation and supplys running out. Thanks for the info!
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.
one of the most useful videos i ever seen in youtube about soldering thanks a lot
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
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?
“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
Solder paste, flux is really magical!! 😅 it makes your work damm professional
Yoo this was very useful. I haven't done it in 5 years and just watching you work brought it all back
thank you electronoobs please produce more videos like this it helps me alot wondering specially on a tight budget like me in prototyping
This was extremely helpful and one of the better soldering tutorials I have seen. Thank you!
thank you my good man, I was finally able to properly solder SMD components!
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 🎉
Thats the best resolution and depth perception together with magnification i have ever seen in youtube videos for rework....tks
One of the practical videos I saw, specially the brief explanation about tip sizes.
A tutorial of desoldering those SMD components would be awesome!
Such a nice idea. I might do it soon!
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
Thank you. I am going to attempt a repair of a surface mount PCB and this tutorial is exactly what I needed.
It was the best video which taught me something new and pointed me my previous mistakes that I was doing years long....
The best soldering tutorial I have ever seen !
I could never solder SMD on a PCB before, until I bought a freaking microscope. Now it is easy peasy.
Thank you so much, I learnt something new, I am used to soldering old school back mount components. You did a good job explaining the process.👍😁
Sounds like Bob from Bob and Cedric on Seinfeld. Love it.
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
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
Very well and clear explanations of the soldering tools required for beginners. Great !
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.
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.
Very high quality video as always , I love the hard work you put to videos
Such a great video. You explained each and everything perfectly that even a noob will understand. Lots of love from Nepal.
Your video is very, very helpful. It shows that soldering SMT can be done with a soldering iron. Thank you. Gives me confidence to try myself.
AMAZING tutorial and craftmanship. Thank you for video and great attention to detail. 10/10
Amazing, easy explained, organized, short and informative
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 personally think your an expert and your Very professional.
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.😎
Very good soldering tutorial. We are glad that you are happy with our PCB's 🙂
You are the best! Your videos are sooo easy to follow and understand. Thank you immensely!
Thanks for the video. It shows how to solder SMDs using a soldering iron, using the appropriate tip for this type of work.
indeed, i have lost the fear. cannot thank you enough for this video!
i didnt know until i finished this video that this was an amazing video .. this helped me a lot with my work
Best tutorial I've seen so far!
Great video. I especially liked that you showed what can go wrong and how to fix it.
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.
é muito gratificante ver os componentes smd sendo soldado!
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.
this is such a great video. explanations are thorough and very easy to understand. just watched it again! thank you very much.
Your video saved my circuit board 😁😁
I want to try soldering but I could never figure out what I'm doing wrong. Your video explained it perfectly! Thank you!
Very good video, helped me reattach a SMD resistor that fell off my PCB!
A very comprehensive tutorial. Thank you.
After watch this video. I'm become your a subscriber. From Kuwait.
Great video. Love from India. Learnt something new today.
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
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 !
Best tutorial ever. Thank you🙌
Small tip to improve your thermal reliefs, use 0.2mm conductor width and 0.2mm air gap, it will be more efficient. Oh and nice video btw !
Thankyou for this extremely detailed video. Great info. Thank you
This video is worth surface mounted gold.
Well explained and succinct! Thank you!
Huge thanks man, especially with the tool recommendations!!!
Thanks for sharing about how to solder any component.
Wow very not time wasting and very noob friendly I have been looking for this information for many years
Truly a great tutorial, thank you very much.
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
ohhhh I wish I could see this video months ealier, then I would avoid so many problems!! Still, great tutorials, detailed and contains all that a beginner needs.
Thanks man very educational I think I could actually solder a connection
I like ur tutorials that every day I have to download like 5
Great work. How about desoldering? As sometimes it is harder. Also, soldering and desoldering BGA and LGA chips.
Thank you very much, i like this kind of videos, I learn all necessary things one time 😊
Thanks for the tutorial! Lots of great information and ideas that I can use to help set up my SMD soldering workstation!
That was extreme helpful. Thank you man.
Beautiful... Sml this type is soldering is relatively easy compared to iPhone motherboard repair
Well done mate 👏, a pleasure to watch ☺
