I screwed up a ram chip repair - thrashed circuit board - can a newbie recover?
Hi all,
I have attempted a repair on an arcade game and damaged the board. I've done these things before successfully so I'm not completely a newbie but I'm certainly not "seasoned" at this stuff. But here's what happened.... There was a bad RAM chip soldered to the board. My plan was to solder in a socket for the repair. I clipped the old chip off and removed all the pins. But had difficulty extracting a couple of them because I clipped them to short. So I removed them from the other side but ended up doing 2 things. First, I pulled away part of the traces because the board is very old. Second, since I insisted on moving forward even though I didn't really have the right tool (my soldering iron tip is like the size of my thumb), I ended up scorching the board a bit in that area so I can't even see where the traces should really go. It's a Zaxxon game. I have a schematic....and can sort of read them... sort of....is there hope for me fixing this myself? The value of the game isn't really high enough to justify a professional repair guy. Thoughts? Thank you! |

First, get a proper temperature controlled soldering iron with
a suitable tip. You can cut the damaged traces with an x-acto knife and solder 30 ga. jumpers (use wire intended for wire-wrapping, and get a proper stripper for it, as it is delicate) to the traces where they are cut to the components. jhuie wrote: Hi all, I have attempted a repair on an arcade game and damaged the board.
