The holes above the pads should have continuity to the pads when you check with an ohmmeter. Easy test. Clean it, either way.this is a cps2 board that was in a cabinet I just picked up. Haven't tested it, but what do you guys think? Is this a problem? I'm not sure if continuity is lost in any of these ?
Thanks in advance!
It's really thin wire. Kynar AWG30.what is stripped K30?
That ^It's really thin wire. Kynar AWG30.
I should mention I wouldn't have covered the entire keypad in solder, beware as insertion/removal of the JAMMA edge will scrape off.It's really thin wire. Kynar AWG30.
If possible try to stay out of the red zone...
is the acrylic overcoat pen adhesive and conductive?Not sure if this is the best advice but what I'd do is first remove the excess solder in the pads, then remove all the corrosion using a fibreglass pencil (be careful to not breath the dust!), clean with 99.9% isopropyl alcohol and apply deoxit in the metallic pads and acrylic overcoat pen to fix the damaged solder mask.
An now, I finally have a reason to read A-P with my wife...If you don't want to spend that kind of cash you can just go to Walmart and buy some nail polish to cover your repairs or replace solder mask. It's what I use. I have two different shades of green.
Also, don't worry about the colors with the sparkles in it. It's not metal flake, it's plastic so not conductive. Finding a normal color shouldn't be an issue though.
Bypassing the broken button should work.I have one more query. The board has some faulty volume buttons. Not the plastic piece, but the actual SMD buttons. Volume down and test work, but volume up doesn't. I've tried to raise the volume via the cps2 kick harness and bypass the buttons on the pcb. It still doesn't register volume up. Is that normal? I figured bypassing the actual broken Button would work.
