I want to know what caused it, whether it was the power supply or the conductive metal, and I want to see if I can fix it myself. I have a soldering iron, so if it does include soldering, I can do it.
I suggest listening to, or reading the transcript of, this presentation from the designers of the RP1 chip.
RP1: the silicon controlling Raspberry Pi 5 I/O - https://www.raspberrypi.com/news/rp1-th ... pberry-pi/
There is potentially relevant information from timestamp [25:28] labelled “Substrate fun”.
The RP1 package is 12mm x 12mm. Pretty small. And the connections to it are via BGA in an 18x18 grid. Not simple 'pins.'
Mere mention of a soldering iron suggests you don't have a clue what is involved.... If you CAN do it lots of people will be impressed...
