  • Electrical contactor for automatic testing of chips including RF chips
    Patent number: 6437585
    Abstract: An electrical contactor for establishing an electrical contact between a chip and a printed circuit board for testing chips comprising a conductive layer and a ground contact pedestal. The ground contact pedestal is preferably press fit and soldered onto a ground layer of the printed circuit board for establishing good ground contact with the chip. In addition, the contactor preferably has a thin profile that does not electrically interfere with sensitive electronics contained within the chip. The contactor also does not use a plastic frame for mounting purposes. Such plastic frames reduce accessibility to the printed circuit board, making fine tuning electronics in the printed circuit board more difficult. Rather, the contactor preferably includes two holes in its conductive layer that mount on dowels in the printed circuit board and is secured to the dowels by two O-rings.
