With a total of two patents to his name, Dorey has developed innovative methods that enhance the manufacturing processes in this critical area of electronics.
Latest Patents
Dorey's latest patents include "Additive processing electroless metal plating using aqueous photoresist" and "Selective metallization process." The first patent describes a method for making a printed circuit board that employs an aqueous type photoresist. This method includes etching the substrate surface with chromic acid after applying the photoresist mask, followed by washing chromium from the surface with a reducing agent at a pH of less than or equal to 10. The second patent outlines a selective metallization process particularly suited for making printed circuit boards. This process involves treating a substrate with a negative mask using a reactant, such as acetic acid, which modifies the surface of the mask without affecting the substrate. This modification prevents an active catalytic layer from remaining on the mask's surface, thereby inhibiting electroless plating on the mask.
