Title: Molded articles suitable for adherent metallization, molded metallized articles and processes for making the same
Inventor: CLEVELAND ERIC J
IPC: H05K1/02
Filed: 1986-02-14
Abstract: The molded one-piece articles may be formed by molding into a first mold cavity a first portion of the article using a first electrically insulating material which is adhesion promotable by an adhesion promotion process and is catalytic for adherent metallization, or is capable of being rendered catalytic for adherent metallization by an activating process; inserting the first portion (30) into a second mold cavity (52); and molding into the second mold cavity a second portion (56,58) of the article using a second electrically insulating material, leaving selected surface areas of the first portion exposed.
