A device (100) for use in a test fixture system which uses a plurality of ultrasonic transducers (103,105,107) to transfer energy to a plurality of contact probes (109). The ultrasonic energy enables the pins (111) to pierce and move obstructing materials to insure adequate electrical contact between the contact probe and an electrical connector on a device under test.
