Whoops... Scratched the Cell while removing its IHS

**Pereb27** · 08-21-2011,03:03 PM

Hello.
So, I successfully removed the IHS from my PS3's CPU in order to change the thermal paste (did it by sliding/shoving a razor blade in to cut the silicone/epoxy/whatever sticks the IHS).
However, I noticed I did some light damage to the PCB (the actual CPU PCB, not the motherboard). A few copper traces were revealed at a few points and there was even a nice cut.
The razor blade was parallel/almost parallel to the PCB all the time so I do not believe it could have cut too deep.
The PS3 still boots fine, however I'm scared that there is actually a cut trace on that PCB and something will end up not working. Anyone experienced here could tell me if there is something to worry about? Or does the fact it boots fine means there shouldn't be any issues?
Thanks.

You just scraped some of the solder mask away. Not really a big deal. That exposed copper is now a direct link to whatever via's or chips that are connected to it. However as long as you don't make any physical connections to it you should be fine.

Alright, thanks for confirming

I'll just cover the exposed copper then.

How about putting a drop of epoxy or hutglue over the exposed traces, just a thought.

I used non-conductive thermal adhesive on it. Epoxy would probably be too thick, and idk about hutglue.

You might try a thin coat of nail polish enamel... seems similar to the coating on the pcb anyway.
