Introduction

David A Brouchous is a notable inventor based in Hutchinson, MN (US). He has made significant contributions to the field of plating chemistry, particularly in the development of neutralizing compositions that enhance manufacturing processes.

Latest Patents

David holds a patent for "Microetch neutralizer chemistry for Ni—Au plating defect elimination." This innovative neutralizing composition comprises ascorbic acid as a reducing agent, citric acid as a chelator, and a pH adjusting agent. It is specifically designed for application to microetched copper substrates that are bonded to stainless steel, which have been cleaned with an agent containing permanganate ions. Unlike prior art neutralizing agents that utilize oxalic acid, which can leave insoluble residues on copper surfaces, David's composition leaves no residue and acts quickly. This advancement leads to a surprising reduction in defects in Ni—Au plated copper substrates during the manufacturing process.
