Dear all,
I guess there are two basic types of Cu-clad polyimide: Cu-clad polyimide with adhesive and adhesiveless Cu-clad polyimide. I am curious as to the relative cost of each, and the advantages or limitations of using either one. The end use is Class 2, Type 5A (flex to install), in a (fairly) sealed enclosure that will see temps of -20C to +85C. Only two copper layers, no plated holes.
In the past our FPCs have always been of the Cu-adhesive-polyimide type. I want to know if there would be any advantage to using the adhesiveless stuff, besides thinner circuits.
Cordially,
