Latest Patents
One of Tokumaru's latest patents is the "Antistatic Socket Apparatus." This invention establishes an electrical connection between a measurement instrument and a semiconductor device that has internal elements sealed in a non-conductive package. The design includes leads that protrude from the semiconductor device when mounted on the antistatic socket apparatus. The socket is constructed from a non-conductive material that allows for the diffusion of static charges while maintaining adequate electrical insulation properties. Protrusions on the mounting surface of the socket support the package through contact surfaces, which have a total area smaller than that of the mounting surface, thereby reducing static charge generation from frictional contact.
Another significant patent is the "IC Package Inspection Apparatus." This apparatus is designed to inspect the outward appearance of IC packages stored in embossed tape. It features a drive wheel that rotates in a vertical plane to move the embossed tape. A pair of cameras are strategically mounted to capture images of each IC package from different angles, ensuring accurate inspection without light reflection interference from the cover tape. This innovation prevents any inclination of the IC packages during inspection, enhancing the reliability of the inspection process.
