Homebrew PCBs

My stock includes 0.008 and 0.016 thick SS clad.  I have some 0.032
DS.  What I normally do is mask and etch the two (or four) sides
separately, then adhere them with double-sided sticky tape and drill.
For small boards, I do both sides on one piece of PCB and cut them
apart, saving time.

Two 0.16 taped together yeild a 1/32" DS.  If you add two 0.008 outer
layers it's a bit thinner than standard 1/16" boards (the copper and
tape add thickness).  However, it's much easier to cut 0.008 and 0.016
than 1/16" - so I do most of the cutting *before* taping, then sand or
file the edges smooth afterwards.

Also, the thinner boards work much better in the laminator.

I do have some 1/16" stock but as it doesn't fit in the laminator, I
only use it when I need the extra strength.
