A few remarks here:
- Use flux when removing but also when putting things on. It can be cleaned off easily. It will help the solder going to where it should be.
- To remove the solder, use flux, put the wick on it and then press on it with a soldering tip. The wick will pick up all the excess solder.
- Apply a little bit of solder on the tip of your soldering iron, have some flux on the pin target area and then see it flow perfectly there. You won't even need to apply pressure.
- On the graphics card it didn't connect because first no flux and second not enough heat on the target. If both is present the solder will flow there nicely.

It all boils down to the right amount of heat, flux and solder.
And a quick tip: For beginners it's easier to work with solder with lead. Just be careful with the fumes. But if only doing it on rare occations it might be fine. And when you're better at it, use non leaded solder!

They make BGA stencils that can also be used for PGA CPUs. The stencils slide over the pins and help keep them in place while you reflow the new ones onto the pads. Some additional heat may be required, since the hot air has to first heat up the stencil.

As a repair tech this was hard to watch lol, good effort jay.
1. You need to replace the solder on the CPU you’re working on with leaded solder, it really helps.
2. Don’t be afraid to flood it with flux, flux helps solder to flow and it helps heat transfer, I suppose it’s like thermal paste sealing those air gaps.
3. Don’t use too much heat in one area for too long, that can cause ‘pop Corning’ which is probably why you lost the pad, the technique is to circle the area to heat the board before you focus the area you’re reworking.
4. Use your palm as a rest to stop your tweezers from shaking, fine control is really important.
5. Regarding the GPU, that’s a 12-14 layer board, it will suck the heat away, you need a very powerful hot air station to remove that resistor, and your soldering iron won’t cut it either. You need a hakko soldering iron.
These tools should be fine for the cpu though.

Great video. I always tell my daughters, "Failure is the first step towards success." It is never about getting it right the first time, but rather sticking with it. This video shows just that - a great lesson for all.

[CannedLaughter]

The greatest tool I have as a micro- repair tech is resistive tweezers operated by a foot pedal. Forget trying to heat with one hand and hold with the other, it does it all in one. By far my favorite tool.

Just a reminder your channel has the best camera man. Even in random videos that have tone of movement the shoots are great in focus, stable great lighting and in general good video quality vs other huge tech channels that spend thousands on "8k cameras" etc that suck in their production quality! Thank you!

[andoman]

Northridge Fix has videos on replacing the CPU pins and the channel is very informative on using different tools and techniques.

Jay, quick tip about stubborn solder that won't melt on the GPU. A lot of factories use solder with a high melting point. A good way to lower the temperature is to apply extra solder that has a lower melting point to the part first then try removing it. Also you need to add flux to the joints when both adding a component and remove one. Good luck and keep at it!

You know the most amazing thing is with these type of videos, is you get to learn from other people's mistakes so you don't have to make same mistake yourself.

As someone that does SMT repair work daily... Equal parts fun to Equal parts frustrating is 100% true. I love my job, but it can be overwhelming at times. Tips:
1. Flux is your friend and there really is never to much.
2. Get your pins/ parts in the general area, apply more Flux then reapply heat. (Don't touch the part while heating again, solder will do the magic for you and pull the part right into place... most of the time)
Best of luck on this journey! Love your quality of content that has always been held as very valuable information to a very avid enthusiasts. Thank you.

My props to Jay even attempting this. I have seen people do this successfully BUT, they are repair technicians that are accustomed to micro soldering and have the proper equipment.

[sirpaco]

Every time I see Jay attempt to do something like this I can see myself and my screw ups... accurate to the point 😂 Great video guys!

[ytQrash]

I recommend watching Graham on the Adamant IT channel repair some motherboards. He provides clear soldering tips while replacing components, including cleaning and resoldering pads. His troubleshooting strategy is also great to watch.

[massimoguasti]

Flux is your best friend for soldering. Also if you want to get something off the board using the heat gun, especially on big board and big component, you need to have lot of heat for a short amount of time, so you avoid melting the component. You can preheat the board as well, to make it easier, as those board dissipate lot of heat.

I absolutely loved soldering when I was in high school, but there have been many advancements since then. To see all the things they have for modern soldering was really cool. Thanks for trying it out, and I look forward to seeying your progress Jay.

Jay, I really liked this video. I built electronic kits starting at age 12, and for the first five or six my father had to fix my damage - which he somehow did 100% being a professional TV Repair person. The only thing I can say is that soldering is all about the repeated practice. You are also at a distinct disadvantage by start with items being so small. The way I learned was starting with big and moving down the size scale. You do have me tempted about doing it all again after a number of years doing computers and computer security, but that is not likely until I can retire from my Day-Job and have enough YouTube subscribers to have things moving along smoothly.

By the way, I would still try that CPU in the CPU socket, since many of the pins are not actually used, or are being used for a peripheral that you you do not have in that system. Good luck.

I'm pretty sure it's a good idea to apply flux even for the removal of a very basic component. Also, you could have just applied that type of flux that incorporates micro-spheres of solder into itself, onto all the pads, sticking pins on each of them, and attacked the entire thing at once with the heat gun. The melting solder blobs and all the surface tension happ'nin's should just put everything in place.

[ShRk]

Hey Jay!!! I'm no expert either, and I wouldn't even attempt a CPU pin replacement myself but I do have plenty of amateur experience doing this for fun (fixing stuff for myself or others). Whatever the others say, I commend you for trying!!! If you enjoy it - stick with it! Watching Louis Rossman, NorthBridgeFix & ElectronicsRepairSchool over the years I'm getting fairly proficient in fault finding too, but you're certainly starting at the deep end!!!

that opening made me think of annoying orange lol

@JayzTwoCents
As someone who has been soldering since he was 6 years old, I have alot of experience. You're doing very well for someone just getting into it. You already know you need practice(practice makes perfect) and you seem to be making solid progress. My only two points of advice are about the use of the hot-air-blower and flux. Generally hot-air-blowers are used for removal of parts, not for attaching them. Use the soldering iron with a precision tip for soldering parts(like those CPU pins). About flux: Be generous! It's always better to have too much than too little. Don't worry about making a mess with flux, it cleans up easily with IPA and a soft-bristle toothbrush. Beyond those two points, you're doing very well! Forge ahead good sir!
