Title: John L Cordani: Innovator in Multilayer Printed Circuit Technology
Introduction
John L Cordani is a notable inventor based in Waterbury, CT (US), recognized for his contributions to the field of multilayer printed circuits. With a total of 12 patents to his name, Cordani has made significant advancements in the technology that underpins modern electronic devices.
Latest Patents
One of Cordani's latest patents focuses on a process for fabricating multilayer printed circuits. This innovative method aims to enhance adhesion between copper circuitry innerlayers and pre-preg layers. The process involves applying a conversion coating of copper oxide on metallic copper surfaces, which alters the topography of the underlying copper. Following this, a controlled dissolution and removal of a substantial amount of the copper oxide is performed, ensuring that the topography of the metallic copper remains intact. This results in innerlayers that consist of topographically altered metallic copper with a minimal amount of copper oxide. The outcome is excellent bonding strengths and a reduced incidence of pink ring formation compared to traditional methods. Additionally, the copper ion-containing solutions from the controlled dissolution can be economically utilized in formulating electroless copper plating baths.
