Removing silicon from pcbs (leave the copper patterns) Answered

How can you dissolve the silicon (and possibly solder) off of a PCB to leave the copper traces? Thanks


. You can melt the solder and either blow or suck it off.
. Don't know about the PCB. I thought PCBs were made out of fiberglass and resin. The only thing I can think of that will eat silica(tes) is HF and that will eat everything.

. You need something to dissolve the resin that binds the fiberglass strands together. I can't think of anything that will dissolve cured resin. Maybe something used for resin cleanup during manufacturing?

no (thats some scary sh1t!) I don't light that stuff any more. I did find another way to get a similar effect, but I'm still looking for ways to dissolve it.

That's good then. Don't want to catch anything on fire that shouldn't be on fire...

I'd be warm for the rest of my life! LOL!

thatd be kinda cool, but I think the copper traces would be a bit fragile.

Yeah, they would. I want to transfer them on to glass or something like that
