Title: Innovations of Robert A. Sabo
Introduction
Robert A. Sabo is a notable inventor based in Smithfield, Rhode Island. He has made significant contributions to the field of flexible circuit technology. With a total of 2 patents, his work has advanced the methods of fabricating flexible circuits for integrated circuit interconnections.
Latest Patents
One of his latest patents is titled "Method of fabricating flexible circuits for integrated circuit interconnections." This patent describes a method for creating a double-sided electrical interconnection flexible circuit, which is particularly useful as a substrate for an area array integrated circuit package. The process involves pressing a copper matrix with studs through a dielectric film that has a copper layer on the opposite surface. This results in an intermediate structure for a flex circuit with self-aligned solid copper vias in a one-step process. The contacts are reinforced by plating both surfaces with a layer of copper, and conventional processes are used to complete the circuit patterning.
Another significant patent is "Flex circuit substrate for an integrated circuit package." This invention details a double-sided electrical connection flexible circuit that serves as a substrate for an area array integrated package. The method of fabricating this structure is also described. The circuit features interconnections on one surface and solder ball contact pads on the second surface, interconnected by copper plated from a single surface to avoid air pocket entrapment. In one embodiment, the conductive vias are formed from a copper film extending from the solder ball contact pads, which may be indented to provide a well for solder balls in the contact pad.
