Latest Patents

One of his latest patents is titled "Microetch neutralizer chemistry for Ni—Au plating defect elimination." This invention introduces a neutralizing composition that utilizes ascorbic acid as a reducing agent, citric acid as a chelator, and a pH adjusting agent. This composition is specifically designed for microetched copper substrates bonded to stainless steel, which have been cleaned with an agent containing permanganate ions. Unlike previous neutralizing agents that used oxalic acid and left insoluble residues, Pesavento's composition acts quickly and leaves no residue, resulting in a surprising reduction in defects on Ni—Au plated copper substrates during manufacturing processes.

Another significant patent is "Plasma treatments for flexures of hard disk drives." This patent outlines methods for producing flexible circuits by treating the surface of the flexible circuit with atmospheric plasma or a beam of ions. The atmospheric plasma is generated by directing a flow of gas between an electrode and the flexible circuit, creating a plasma from the gas through voltage application. The ion beam's mean energy ranges from about 500 electron volts to about 1,500 electron volts, showcasing innovative techniques in circuit production.
