Title: Innovations by Keith L Casson
Introduction
Keith L Casson is a notable inventor based in Northfield, MN (US), recognized for his contributions to the field of electronic circuit manufacturing. With a total of six patents to his name, Casson has made significant advancements in the design and functionality of multilayer electronic circuits.
Latest Patents
One of Casson's latest patents is a method of manufacturing a multilayer electronic circuit. This innovation features a heat-resistant multilayer circuit board designed for use in various transportation environments, including cars, boats, and planes. The circuit board consists of two or more conductive layers, which are electrically and mechanically connected by an interconnecting adhesive layer. Notably, at least one of the conductive layers is affixed to a heat-resistant substrate. The interconnecting adhesive layer is composed of a conductive adhesive material that contains a plurality of deformable, heat-fusible metallic particles dispersed throughout a non-conductive adhesive. This design ensures that the fabricated multilayer circuit boards have reliable interconnections that are heat resistant and capable of withstanding thermal cycling and typical circuit board finishing and assembly processes.
Another significant patent by Casson is for a printed wiring board that utilizes a photoimageable dielectric material (PID) as its base dielectric substrate. This innovation allows for improved resolution and registration precision of access apertures and through holes in conventional printed wiring board designs. Additionally, the use of PID material simplifies the manufacturing processes required to deposit, image, develop, and cure the material, making it a cost-effective solution.
