Hi,

I've been parting out some rather large junked but new-ish photocopier
SMPS boards, as large as ~ 11"x12" in ali chassis, and eyeing up the
quality fibreglass PCB itself. Wide traces and groundplane areas, and the
thought has occurred to me to strip off the actual traces and re-use
sections of the boards with eyelet tags or turrets for my own projects.

Any ideas as to how to go about effectively lifting the copper traces to
get it back to a blank fibreglass board?

Thanks, RdM

I don't know how you could possibly re-use it, but scortching it hard
and fast with a blowtorch will make the traces easy to peel off. The
real trick will be applying new traces.
