摘要:
Disclosed herein is a method of manufacturing a package substrate with a fine circuit pattern using anodic oxidation. By anodizing a metal core which is opened through a masking process, oxidation layers are formed in open areas of the metal core to insulate portions of circuit pattern from each other. Further, by electroplating portions provided between the oxidation layers with copper or filling conductive paste between the oxidation layers using a screen, a package substrate having a fine circuit pattern is achieved.
