Gregory's Serveranyway, i could fix up a few footprints but this reverse engineering job is essentially completed. you can find the design files here: https://github.com/schlae/Thinkpad700CPower

@tubetime Amazing job, would love to see a video on how exactly you go about it.  reassembled like a magic trick. the layout CAD was quite helpful for finding footprint locations.  @tubetime That's amazing. What's the quote? Ah, yes. "Sometimes, magic is just someone spending more time on something than anyone else might reasonably expect." -- Teller @tubetime Wow. How in the world do you figure out the middle layers? It’s a good thing this one was only four - I think some modern PCBs are 12+ layers. The aim is not to be able to re-make a PCB, but just to be able to debug one? @gogobonobo the thread explains how i did it. higher layer count boards require more invasive methods. but yes i wanted to be able to debug boards corroded by a leaking capacitor. |
i haven't reverse engineered many 4-layer boards, but i'm kinda amazed it worked out this well.
