Abstract

Polyetherimide-metal laminates are formed by etching the surfaces of a polyetherimide web with a glycol-containing etchant followed by electroless nickel or cobalt deposition and then by copper deposition. The glycol-containing etchant can be utilized to form through holes through the web.
