Title: Hiroshi Arisaka: Innovator in Electrical Connector Technology
Introduction
Hiroshi Arisaka is a prominent inventor based in Tokyo, Japan. He holds a total of 8 patents that showcase his expertise in electrical connector technology. His innovative designs have significantly contributed to advancements in the field.
Latest Patents
One of his latest patents is an electrical connector comprising a multilayer base board assembly. This PGA connector for a microprocessor features a multilayer base board assembly with alternating conductive and dielectric layers of preselected thicknesses. Signal pins, current source pins, and a grounding pin extend through these layers, with the signal pins insulated from the conductive layers. The current and grounding pins are connected to preselected conductive layers. A series of connecting apertures formed by holes with respective conductive linings extend through the layers at selected locations between pins to interconnect selected conductive layers. This design enables improved shielding and impedance regulation and matching.
Another notable patent is a connector assembly for film circuitry. This film circuit connector allows respective conductive tracks in film contact areas on front, mating faces to be pressed together into electrical connection. The design includes a metal channel-section receptacle spring and a compressible elastomeric plug spring, which engage respective rear faces of the films. The compressible plug spring provides a counter-force to the receptacle spring force, ensuring constant contact force between all tracks. The film is designed with windows for exposing conductive tracks for connection to a circuit board and pockets for trapping board-mounted solder pads.
