Abstract

An improvement to the component mounting arrangement described in U.S. Patent 3,647,533 is described. The method of producing bonding bumps described in that print generally comprise the steps of: 1. affixing a patterned mask to the substrate onto which bonding bumps are to be placed, and 2. depositing metallic conductive material through the mask and onto the substrate. The general method encompasses a number of embodiments, particularly including: 1. the deposition of copper onto a conductive layer previously located on the substrate; 2.
