DENDRITIC ELECTRICAL CONTACTS AND CONNECTORS

摘要

DENDRITIC ELECTRICAL CONTACTS AND CONNECTORS An electrical contact is provided by forming on a contact pad or contact surface a bunch of tiny resilient metal projections by a dendritic growth thereon of conductive metal crystals. A separable or disconnectable electrical connection is provided by urging the dendritic projections on mating contacts into intermeshing or interwedging engagement. Good quality submillimeter size electrical contacts are readily fabricated and are particularly useful for providing low cost spaceefficient multipoint connector systems for large-scale integration (LSI) circuit modules, printed circuit cards and boards and other modern day electronics hardware.
