Title: Innovations of James F Battey
Introduction
James F Battey is a notable inventor based in Los Altos, CA (US). He has made significant contributions to the field of printed circuit board manufacturing. With a total of 6 patents to his name, Battey has developed innovative processes that enhance the efficiency and effectiveness of copper etching.
Latest Patents
One of his latest patents is a copper etching process and product particularly suitable for use in the manufacture of printed circuit boards. This process involves etching copper in a liquid etchant, where the crystal structure of the copper is carefully controlled to provide an anisotropic etch. The vertical-to-lateral etching ratio is greater than 1:1, which is crucial for achieving precise patterns on circuit boards. In one embodiment, the etching solution contains nitric acid, copper nitrate, or sulfuric acid, along with a polymer and a surfactant. The copper used has a top surface crystal structure predominantly oriented in the (111) direction. Another embodiment utilizes hydrogen peroxide and sulfuric acid, with the copper foil exhibiting a crystal structure with predominantly (311) and (511) orientations, as well as (111) orientation. This innovative approach results in a printed circuit board that has a copper foil with a crystal structure selected to provide anisotropic etching, ensuring high-quality manufacturing.
