Method for partially plating on a base

摘要

A base of synthetic resins or other materials is partially plated. The base includes not only a single base but an assembly with a number of chip bases for producing electronic and electric parts such as printed circuit board, lead frame insert molded circuit parts, etc. A method for partially plating a base by the use of a plating catalyst includes a coating process to coat a surface to be plated or not to be plated by means of a coating material selected from a water soluble polymer or hydrolyzable polymer either before or after a catalyst applying process to soak a container containing the base in a plating catalyst bath.
