Homebrew PCBs

Stefan,

I believe that horribly stuff I have been having all the trouble with 
is FR4 material - this is the new stuff I got that wouldn't accept the 
toner transfer until I did the pre-etch.  However, I was also doing 
toner transfer of legends on the bare expoxy side too and it wouldn't 
take either until I sanded it with 600 grit paper and then polished it 
with 0000 steel wool.  After that, the toner stuck pretty good to the 
epoxy.  This was done using a magazine page and an iron.
