Abstract

A circuit board for semiconductor packages capable of fabricating a large number of semiconductor packages in a single circuit board, the circuit board including: a resin layer in the form of a rectangular sheet with first and second sides, the resin layer having a plurality of through holes arranged in rows and columns sharing a sub slot of a predetermined length as a common boundary to form one sub strip for mounting a semiconductor chip, a plurality of the sub strips being arranged in a row and sharing a main slot of a predetermined length as a common boundary to form one main strip; a plurality of circuit patterns each formed in the resin layer between the through hole of the individual sub strip and the sub slot; and a cover coat coated on the resin layer for the purpose of protecting the circuit patterns against external environments.
