  • Metal coated laminate products made from textured polyimide film
    Patent number: 4725504
    Abstract: One or both surfaces of a uniformly and completely textured polyimide sheet are coated with a layer of electroless nickel or cobalt and a subsequent layer of electrolytically applied copper yielding an adhesiveless laminate useful in the production of electronic circuitry. The copper and nickel or cobalt layers are strongly bonded to the textured polyimide sheet to the extent that the laminate exceeds bond strength requirements as measured by current standard peel strength tests of the Institute for Interconnecting and Packaging Electronic Circuits (IPC) for both initial and post solder float adhesion.
