Title: Composition containing heterocyclic nitrogen compound and glycol, for texturizing resinous material and desmearing and removing resinous material
Inventor: GRAVES JOHN E
IPC: H05K3/26
Filed: 2002-03-07
Abstract: PROBLEM TO BE SOLVED: To obtain a solvent swell composition used to condition a resinous material for imparting a porous texture to the resinous material and desmearing and removing the resinous material from a substrate. SOLUTION: The solvent swell composition contains a heterocyclic nitrogen compound and glycol and is used to condition the resinous material for etching to form the porous texture on the resinous material. The porous texture permits the deposition of a metal on the resinous material such that a high integrity bond is formed between the textured resinous material and the deposited metal. Such a bond between the resinous material and the metal prevents delamination of the metal and resin bond. The composition can desmear the resinous material from the substrate. The composition may be employed to treat a resinous material used in the manufacture of a printed wiring board. The metal may be deposited on the textured resinous material by a suitable plating method.
