Soldering has never been so emotional

I managed to weld a 0.5mm QFN 28. I learned with you. Perfect! Thank you very much!

Two o'clock, middle of the night and I’m watching some random dude soldering... Good night

The tears that will drop from my eyes by watching this video will wreck all my soldering

This method looks very easy. But practically it is not. Usually we happen to do this kind of work as a rework. There are many parts already installed nearby. Here there are no other parts, no pads connected to ground. The thermal pad of the chip was ignored. And the board appears to be a double sided (two copper layers) only. When it comes to a board of eight ten layers with heavy density of copper and several pads connects to ground , picture is completely different. We have to use a hot plate to preheat, under the cradle, which holds the board and place everything under the microscope. Then we have to perform the soldering as in the video, sometimes with the help of hot air gun. Everything should be done very carefully, taking care not to burn any connector or part because under the microscope we can see very limited area only. When we perform our duty very carefully, the worst thing is our employer used to bring his laptop to show us these type of videos and points us " See , how quickly the youtubers do this."!!!!!!!!!!!

This method only works well for a footprint designed for "handsoldering" with iron. That is why pads on breakout board are long enough so it is easier to get heat transfer with regular soldering iron tip.

Dont forget the power pad under the part, you need hot air to mangage to that :)

Excellent macro photography and editing. Perfect soldering technique 👍👍👍👍👍

I've never seen something so beautiful in my life!

Dude, you make this look like art

Damn... the music makes it soooo refreshing

Thanks for making this video, I'm getting in to SMD/SMT boards myself and this video was very well presented and explained :) I'll subscribe :D

Perfeito! Eh gratificante e relaxante ver um trabalho assim bem feito

i like your confidence anchoring the second spot without checking if there is any misalignment..

Still came out clean and perfect!

Very nice work. Great close-up.

Прекрасная пайка,очень аккуратно и с умом!

Nice video, love the wave effect. It's so easy on boards without ground planes and on leaded solder though. And no thermal pad. Can be a living hell without preheater on bottom and proper temperatures/times.

watching this makes me ask myself why I waited so long to get into SMD (as a hobbyist)

Simply the best !!! 👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻

If there was a reaction of I love it on youtube I would put it ... that work so neat and perfect I loved it

Nice video, like the music.

MUY BUENOS TUS VIDEOS GENIO NOS INSPIRA A TODOS LOS QUE HACEMOS ESTO SALUDOS DESDE ARGENTINA

Muito bom seu trabalho, deixo aqui saudação do Brasil.

epic skill. thank you for the tutorial

I think there is a big issue, no solder on the ground/central pad if it's necessary.

This is such a beautiful video

Very professional, excelent work

Great Job !!! Thanks for the cognitive Video =)

Beautifull work!!!

The advantage you have here is the large pads to allow you to use a relatively large tip when soldering. It's sucking the solder up from the joint. Problem is that when you follow the manufacture's footprint guide you get minimal area. In production thankfully I'm using a stencil and a convection oven. But sometimes I do need to rework these devices and what I do isn't too dissimilar to this video. Using a large chisel tip iron, lots of flux (liquid rather than paste) and make a big blob of solder to be dragged along the side of the IC. Replacing these ICs you need hot air. What I've also found is that with ICs that have a large thermal pad you also need to add a heater underneath the board. Set it to 100 / 150C so that your hot air has less work to do. You'll do less damage, or none at all, this way! Replacing just carefully put down some solder paste, you don't need much, and then again back to the hot air. But they really are an absolute pain these packages!

Super sprawa szybko i dokladnie

not good, need thermo fan for soldering central thermopad chip

I enjoy listening to the backgrond music.... very relax.

Отличная работа👍

Great job!!

you make it look so easy

this is so satisfying

Красиво! Спасибо!

*C'est bien présenté, j'ai compris maintenant comment souder ce type de composants. Merci*

gracias, esos detalles al soldar microchips no lo sabia...

Если так на печатке запаять - не сложно. Плюс брюхо не пропаяно. Я паяю так: аккуратно залуживаю посадочное место и чип. На чипе должны получиться бугорки на выводах. Совмещаю чип и посадочное место. Грею феном до момента посадки. Проверяю микроскопом правильность посадки.

У этой микросхемы должно ещё припаиваться пузо, поэтому - термофен. Нужно облудить все контакты до пайки. То, что ты показал - конечный этап для контроля посадки микросхемы.

Super smooth

Nice camerawork.

I like to use how air for this especially because most IC have middle large contact for ground or for heat dissipation and i like to solder that too.

Просмотрев видео вспомнил ролик где чувак говорил это просто охуеный зум 🤣

the saddest qfn soldering video... :-(

Professional 😍👍

That was nicely done!! What magnifier do you use?

Хорошая работа.

Very good! Trabalho muito bom!

Thank you, cool skills

Thanks for making this video super my friend

Really impressive

Nice video and beautiful music :) Thanks!

2:34 thanks for keeping it real!

Great Vid !

NICE SOLDERING AND VIDEO.

Androkavo congratulations, beautiful pictures. Could you do SMD desoldering - QFN Package?

Use flux to fix the QFN-chip looks like a good idea. I will try this method later.

Good! 👍

Great footage quality. I would aprecheate voice over music. Explaining stuff, pros and cons. Etc.

What a piece of work, Good! But can you show us your soldering iron brand and tin brand, work station brand, and Microscope, etc....

มาเป็น Fc sub ใหม่ครับ

what a great skill

You make this look really easy although I know that it is not, especially with a soldering iron. You must have done this for quite a while now.

very useful video - thanks

Good and perfect skill ever,

for the central ground pad , I would put solder in the hole , from the bottom and heat the pad through the hole with my soldering iron.

This is art

I see this particular package type causing a lot of cold solder failures in equipment we repair. Seems that the TQFP packages are better as their actual leads are more capable of dealing with thermal expansion?

I solder QFN with hot air in 1/100 of the time. The best moment is when the QFN allign itself.

Clean work good

So satisfying, next buy flux. :)

Can you recommend a comprehensive tutorial about the basics of IC technology? (PCB fabrication, main surface amount elements and their function, main applications)

Goog work bro..

Nice work

Theres that damb toothpic and same can of flux....😌 love it lol.😃

А пузо-то не припаял? Надо-бы сначала феном...

Where did you get that metal siphon you had on top of the alcohol bottle ?

I preffer to use hot air to sold QFN's packages, specially because the central pad!!!

Esse cara é fera

i am crying when i see what you do

Funny, taking a QFN package and soldering it to an extension board... Good soldering though!

Чистая работа!)

well done!

Magnificent, dreadful and sad at the same time.

What type of microscope you use??? And thanks for the videos saludos desde mexico

I have same smd soldering process using iron box method simple and easy to use .

Excelente

music so beautiful

You forgot to solder the thermopad/GND Pad that located underneath the chip ,which may be very important for the performance of chip align with the specification.. when soldering QFN with thermopad . hot air soldering and drag soldering method shall be applied

Nice debating if I should get cheap hot air gun or just use my soldering iron to add the 2nd m.2 connector and the capacitors for my laptop MSI decided to leave off.

amazing..

Nice video

nice job thank you

Neat, but not a QFN soldering you expect :) The "real" one is not much harder though, the main difference is you also have to tin the package terminals to get the same pillow shape as you got on the PCB pads. And better use a blowtorch with a catalytic nozzle as advised in some (can't recall which one exactly) repair note instead of hot air gun, makes things way easier as nothing gets blown off.

good soldering

最初の位置決めが一番大事ですね～
