Thanks Kevin - I don't want to apply new traces. I want to re-use it with
inserted rivet-tags (for want of a better word to describe them - I've
scored a ~500ml jar full of silver-plated double-tag eyelet things) or
turrets, in my own pattern of holes, afterward. With heat, I'd want enough
to just loosen the traces (which may be thick enough to "peel") but not
scorch the board. I may try a heatgun first, and if that fails, use etchant.
Obviously the heat method would be *far* cheaper:=}) I guess I'll try it.
