My first GitHub pull request was merged!🤡
I did a write up with the 3D printed jigs I designed for this project. Hopefully now it's also gonna help others with their attempts😂

Kurogane Communication (1998) predicted the existence of M.2 SSD👀
Interesting graph showing spinning rust being slower on the inner tracks, down by almost 50%👀
So I added a bit more good flux and reflowed until everything looked fine.
Then I removed the helper PCB and fixed two loose pins with hot air and more flux😌
Inspection showed no short at all!🤪
Then, I put back the helper PCB and fitted the assembly back onto the jig, so I could solder on the QFP 386. It was a walk in the park😌
Today I decided to finish putting this project together here. It’s a set of PCBs to convert a QFP 386 CPU to PGA.
First, I used the stent to apply the solder paste to the main PCB. It went on smoothly (pun not intented 🤡)
If you are also interested in hand-crafting your own PGA 386 CPU, here is the project I used:
[386DX QFP -> PGA Adapter]

Then, I took the PCB out and closed it onto the pins I put in place last night, using the jig I designed, and transferred the assembly onto a bigger PCB as a hotplate.
Got burnt by steaming hot steam while cooking.
Held an ice pack in hand for the rest of the night.
Wake up in the morning and the damage is almost gone.
Very important to keep the burnt area chilled for hours! It also soothes the pain!😌
Finally, I verified all the pins and they all checked out fine! Now I can use it to actually repair the various broken motherboard I have on hand🤡🤪
