Latest Patents
One of Yamaguchi's latest patents is for a hermetic organic/inorganic interconnection substrate for hybrid circuits. 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 a strong electrical connection with the post. A conductive pad can then be stenciled on top of the solder plug, allowing for the mounting of chips or other electronic components. The process involves plating the holes with a conductive material before filling them with solder, ensuring a robust connection. The solder plug is created by mixing 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.
