Subject: Q: Drilling PCBs

From: "Adam Bradley" <adam_j_bradley@...>

Afternoon all.

I've made a couple of attempts at etching/drilling and have had a few
tracks lift during drilling.

I've always lacquered before drilling and I'm beginning to think this
should be left until after I drill.

Any other issues that could be causing this? I suppose the key is
super sharp bits. PS: I'm using a 20k RPM 'dremel' like tool and non-
tc drill bits (yet). Have yet to find a source for them in Australia.
