I just removed the filter board out of my pacman. I am getting a waving flag effect on the maze. (like the maze is floating in water). I noticed that the edge connector on the main pcb is toasty looking on the end trace which I think is the ground. I am replacing the connector with a molex from Bob Roberts, but how do I fix the burned connector on the pcb edge? Do I drag/float solder over the old damaged connection? I think the poor ground connection may be causing the waves in the monitor.

That's how I do it. It's not the prettiest, but it damn effective.....and should last a lifetime.

Or you can send it to me. :D I've been working on this particular repair as of late, and I've almost got it perfected. I was going to wait another few days to post on the subject, with pictures and such, but you beat me to it! :p
 
I use copper trace tape to repair those...

Here are a couple of pics of a Pac Jr. board I repaired.

Take a sharp knife and cut the bad trace. Peel it off the board if loose. If not loose use a soldering iron to heat it up to where it can easily be peeled off.

The trace is the same on the top & bottom so just wrap the tape around the board edge from top to bottom and solder it to the existing trace on the board.

That is a very nice way to do it...

I bought it from Fry's but they have since stopped carrying it. GC made it.

Right now I'm looking for another source.

OK... back on subject... take your phetishes elsewhere.

GC Electronics, part 22-509 has been discontinued.

I've checked over 1/2 dozen places today and nobody has it. Their websites say they do until you call to confirm.

The good news, part 22-511 is an (almost) identical replacement. It meets RoHS standards now.

The bad news... It's way more expensive.

Newark has them in their catalog for $11.18 each. Ouch.
 
Copper 'trace tape'

Guys,
They use copper tape in the making of stained glass windows and for artsy fartsy girly stuff. You can get a roll of it in various widths from an arts n' crafts store. We have Michaels stores here and they had it last time I looked. I have a 50 foot roll that I bought when I used to do stained glass, it has made dozens of PCB repairs and I barely made a dent in it.
PS if the board is really charred... cut it back and fill it with fiberglass repair stuff from an auto parts store, then use the copper tape. I used to repair burned boards in the Air Force that way and it is a mil-spec procedure!

I use to install rear window defoggers for car dealerships and it used copper trace wires and I had some extra left over and used the scrap rolls and successfully fixed a Neo Geo board with it. So check your car dealership aftermarket install shops and they might be able to hold on to some for you the next time they do one. Even check your semi independent car stereo shops that do butt warmers and tinting for that stuff also.

This is exactly how I fix edge fingers also. IMHO, there's no better method. The tape that I use has several special features...
1/ has special high-temperature adhesive that will withstand soldering temp and help hold it to the PCB.
2/ has built-in anti-oxidents to keep it shiny for a very long time. Has long shelf life too.
3/ Proper thickness for PCB applications. Easy to cut with X-Acto knife.

The product that I prefer is available from Digikey as part# 3M1181A-ND. It's 1/4"x18 yards. It's a bit expensive but it is very application specific so it performs great. I wouldn't use anything else.
