Title: Innovations of Joseph M Shaheen
Introduction
Joseph M Shaheen is a notable inventor based in La Habra, California. He holds a total of 14 patents, showcasing his significant contributions to the field of technology and engineering. His work primarily focuses on advancements in hybrid circuits and interconnection substrates.
Latest Patents
One of his latest patents is the "Hermetic organic/inorganic interconnection substrate for hybrid circuit." This invention addresses the issue of vapor release from adhesives that bond organic multilayer substrates to ceramic layers. The design features posts from the organic layer that are plated sufficiently high to enter holes in the ceramic layer without completely penetrating them. These holes can be filled with solder, which not only seals against adhesive vapor escape but also ensures good electrical contact with the post. A conductive pad is then stenciled on top of the solder plug, allowing for the mounting of chips or other electric components. The process involves plating the hole with a conductive material before filling it with solder, ensuring a strong connection. The solder plug is created by forming a slurry of solder with alcohol, which is then squeegeed into the holes and fused under pressure. This innovative approach allows for the formation of multiple interconnection substrates from a single organic/inorganic panel.
