Technetters,
Does anyone have any experience with dry film adhesion on copper that has
silver plating?
It appears that while being etched, the dry film my people are using does
not adhere very well to the silver plated area and has caused this area to
become etched.
If anyone has had experience in this area, my question would be, have you
tried different brands of dry film and if so, does one work better than the
others?
The etchant we are using is cupric chloride.
Thanks,
Phil Culpovich
