A two-sided printed circuit board, a multi-layered printed circuit board, and a method for producing the same

摘要

A two-sided printed circuit board including a base having a first surface, a second surface substantially parallel to the first surface, and a plurality of through-holes formed in the base; a first conductive layer provided on the first surface of the base; a second conductive layer provided on the second surface of the base; and a conductive particle buried in each of the through-holes in a pressurized state for electrically connecting the first conductive layer and the second conductive layer.
