Best way to lift copper off PCB?

Zero Cool · 19th December 2006, 03:39 PM

What is the best way to easily lift copper from a PCb without damaging the copper?

Can i soak the boards is something, or i wonder if i could heat the boards with a heatgun and lift the traces off. I dont care about the boards after as I have some old PCB's that i would like to remove all the components from, then lift the copper traces off the board for repair of other PCB's.

Circuit medic sells PCB copper trace repair kits but they are very very expensive. and if i can find a way to lift traces off of boards i can do essentially the same thing at less cost.

Eh, its worth a shot anyway, right? got any ideas?

Surely this is what you need then you can cut it to the size/shape you want:

Hi Zc

Some time ago I had copper tracks from a kit epoxy board to lift due to excesive heat from the soldering iron. Heat melts set epoxy resins, so a higher watts soldering iron coud work out.

Next try to clean carefully all residues underside of the removed copper tracks before use them. Art work, dude!

Hope this helps and good luck

Why can't you damage the copper if you're removing it anyway? You can lift parts of traces up with a knife blade and peel the traces off, but it's much harder to cleanly remove large copper areas.

Thanks,

CircuitMedic has these kits and parts:
http://www.circuitmedic.com/products/201-2100.shtml

And they have these copper sheets that car cut out as repair traces. there $35.00 per sheet which is very expensive. I thought it might be interesting to try and lift the traces off PCB's and see if they could be cleaned ane reused.

The copper tape looks interesting and i have seen other copper tape trace repair rolls in narrower widths. I will try those. but i thought it might be interesting to experiment with some of these old boards i have around here.
