- Soldering SMD ICs is not quite simple, but very useful skill. In this video I'm talking about it an trying to give some tips, how to do it.
The music box video is from here (many thanks to the author):
• Music Box - CLASSICS "...
This is my new favourite TH-cam channel - I love these repair videos.
It would be good to know the type/brand of flux, solder and soldering irons you use - as there is lots of choice depending on the situation. You could probably dedicate a video to this - I did a quick search through your video list - sorry if you have covered this and I have missed it. Thank You!!
In this video I used no name cheapest 60W iron from Amazon. The flux is from German company Stanol, also cheap and I got it in electronics store around the corner. :)
When the Apocalypse comes your skills will be in demand. Guard that box of old cards well.
I guess, in that case the box of the old cards will be my least problem ;)
Great repairing! Your solder skills are really advanced and I like that! Thanks for this video. Greez, Peter
Thank you very much! My skills are mediocre at best, but the good news is, that with more practice they improve :)
That tweezer trick is genius! Thank you.
Thank you for these free classes. Really helps me.🙂
5 minutes and the topic is fully covered. Love your videos, man. I have a bunch of dead 3dfx Voodoo 1 cards, will definitely try this method on the chips. Thanks!
Thank you! :)
Happy I found your channel. Lot of fun watching your projects.
Excellent, love the "musical box" tip!
The Mach64. The best ISA video card for the early 486's without VESA bus.
"You will need a lot of flux"

Thanx for the advice. Hope I will be able to fix those compactflash IDE adapters from aliexpress
Tremendous video, excellent work!
Thank you very much for your feedback! Glad you liked it!
thank you for these videos your really good at what you do and your explanations are great
The tuning fork technique is brilliant!
Hi Sir! I use a sewing needle because the tip is smaller, you can see the pins moving when passing the tip
Very nice advice Jorge! I guess, with a needle, it is even better. Thank you!
Well that was a Quick Repair..
Great video! What's the wattage of your soldering iron?
Thank you! The one I used in this video has 60W. I have multiple soldering irons.
What type of flux do you use? Thanks
It's the cheapest no-name stuff from the next electronics store here in Germany, nothing special. Also the soldering iron, which you see in this video is a 10€ 60W no-name toy from Amazon :D
I once read that broken GPUs can sometimes be fixed by baking them in the oven to reflow the solder.
I think LinusTechTips once tried this but failed.
I wonder if this technique would have worked in this case?
its only a short time solution. Reflow is the answer
In that case, it's to reflow solder balls under the GPU, on modern chips. Or so the theory goes, in most of those cases the connections between the chip die and the BGA carrier are irreparably broken, and heat just temporarily makes the broken connections expand to make a connection again. Thermal stress will break it again after some use.
As for this card, getting the entire board hot enough to get the solder to reflow, could damage other components or the PCB.
BTW it's worth pointing out that you need to use good quality solder wick, the stuff with flux built-in. Cheap solder wick has no or very little flux and does not work at all well.
BTW what is the gooey flux you show - looks like the stuff Louis Rossmann uses!
I'm glad you asked :) I'm using the cheapest no name materials from China. All you see in this video is no name and even the soldering iron is a 10€ no name part from Amazon :D Really, no joke.
It's just standard flux paste.
Am i the only one, who had to google what is C3H8O ? :D
Isn't it nice to learn something every day? ;)
PCI cards are plagued with cheap capacitors, bad components, bad PCB and manufacturing process. When I have yet see an ISA card go bad.
I have a box full of bad ISA cards. I don't really feel a difference. On powerful AGP cards and many GPUs however, caps do blow up more often. But this is due to much higher stress and temperatures.
first to post!
Hi Jorge, sorry again for the hickup. My upload was a bit broken :)
This is perfect super-useful knowledge; thanks man.
You are welcome!
Можно говорить помедленнее? Я субтитры с автоматическим переводом читать не успеваю ))) В этом видео прям как из пулемёта...
В Ютубе можно скорость воспроизведения замедлить если что :) Я в последних видосах помедленнее стал говорить.
THANKS !! 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
You are welcome!
thanks for the tip!
I'm glad, if I could help! The community is about to share the experience, isn't it? :)
Sehr gut und irgendwie sieht das so simpel aus. Ich hätte hier eine Voodoo2, die zwar vom Triber erkannt wird, aber nicht in den 3D Modus schaltet. Die ist zwar nicht krumm, aber wahrscheinlich liegt da auch so ein Problem vor.
Ja, bei Voodoo's kommt es sehr häufig vor. Die Teile sind oft sehr heiß gelaufen und haben sich durch ständige Erhitzung und Abkühlung ausgedehnt und wieder zusammengezogen. Dadurch sind sehr viele Karten über Jahre kaputt gegangen. Ich habe ein zweites Video, wo ich auch eine Voodoo 1 auf ähnliche Weise wiederbelebe.
@@necro_ware Ich hab das Problem mit einer Voodoo Banshee, genau das gleiche Verhalten. Optisch kann ich aber nix auffälliges feststellen. Kann man da noch was retten?
@@Kanileini Schwer zu sagen, hellseherisch bin ich nicht so besonders ;) Aber im Ernst, natürlich ist jeder Fall anders und man muss dann sehen, was man machen kann.
Excellent video and exactly the same approach I developed. It's been said that ROHS techniques produce boards that are more prone to cold solder joints, I'm not sure but interested in your thoughts.
Thanks! Well, may be. I believe, that especially ROHS from the early days were worse, but may be it's just the age :)
