Re: Ferric Chloride and silicone ?

2005-11-07 by lcdpublishing

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
