Title: The Innovative Contributions of Michael G. McMaster
Introduction
Michael G. McMaster is a prominent inventor based in Austin, TX, known for his significant contributions to the field of circuit board technology. With a total of 7 patents to his name, McMaster has made strides in developing advanced manufacturing methods for multiple layer circuit boards.
Latest Patents
Among his latest patents is a method of manufacturing a multiple layer circuit board die carrier. This innovative process involves creating stacked vias of fine dimension and pitch. The method begins with a base laminate that has a conductive pattern coated with a dielectric material. This dielectric is then photolithographically processed to create holes that expose selected regions of the underlying conductive pattern. The holes are plated to form via connections, and the recess created by the via is filled with a conductive and plateable polymer, which upon curing forms a conductive plug. A second dielectric layer is subsequently deposited and processed to expose the underlying plated via and plug, allowing for the creation of a second via that is vertically aligned and electrically connected to the first. This technology is particularly crucial for printed circuit board structures, such as carriers for flip chip die, as it addresses the need for fine pitch solder ball arrays to be expanded and disbursed through multiple board layers with minimal area and electrical degradation.
