Title: The Innovations of Stephen Alan Dunn
Introduction
Stephen Alan Dunn was a notable inventor whose contributions to the field of circuit board technology have left a lasting impact. Based in Georgetown, TX, he held a total of 2 patents during his career. His work primarily focused on methods of manufacturing multiple layer circuit boards, which are essential in modern electronics.
Latest Patents
Dunn's latest patents include 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 important for printed circuit board structures, such as carriers for flip chip die, as it minimizes area and electrical degradation while accommodating fine pitch solder ball arrays.
