  • Patent number: 4965865
    Abstract: A probe card provides an interconnection between pads on an integrated circuit chip and leads on a printed circuit board to test the chip operability. The card includes a dielectric substrate having a substantially planar surface and at least one channel disposed in such surface in a particular direction. Electrically conductive material is disposed in the channel to contact a conductive, preferably resilient, probe having a first portion disposed in the channel in abutting relationship with the planar surface on the support. Detents are provided in mating relationship in the channel and on the support to position the probe precisely in the channel. A second probe portion extends from the first portion at an angle to the first portion. A probe tip is at the end of the second portion to contact a pad on the chip.
