[SML] photo etching

[Bruce]

Oh boy.  Chemical etching of a PET base is, uh, tricky.  Have you asked the 
guys at OSHpark or OSHStencils if they have the capability?  They're 
usually down with small quantities.

Otherwise I'm not sure.  What is the metal being removed?  Some of the 
lasers are pretty tunable these days, especially if the metal can be made 
black before etching.
