METHOD AND APPARATUS FOR LOCATING AND TESTING A CHIP

A probe apparatus includes a nest element operable to precisely locate a chip having a plurality of exposed interconnects on a face of the chip to permit conductive connection to the chip through the interconnects. The nest element includes a pocket dimensioned to locate the chip within a tolerance of less than a width of one of the interconnects, and tapered walls extending upwardly and outwardly from the pocket, the tapered walls adapted to guide the chip into the pocket. One or more piezoelectric elements can be attached to or provided within to the nest element to impart vibration to the nest element, causing the chip to be "fluidized" such that the chip is guided into the pocket under the force of gravity or other externally applied force.
