Hi Adrian,
Thanks for the info. The boards do etch fine, I just can't get toner
to stick to them. However, I am sure there is something on the boards
making them stay shiny and also there is a good chance they use
something in the mfg process to lubricate the rollers and such while
forming the copper. However, I would think if they used silicone
during the copper mfg. process, they would have trouble bonding the
copper to the epoxy-glass boards.
WIll report back any further findings...
Thanks again!
Chris
