ABSTRACT:
The present invention relates to a spring probe contactor for testing BGA devices. The spring probe contactor is comprised of a plurality of spring probes for providing a connection between a BGA device to be tested and a DUT board. The plurality of spring probes are held within a contactor block having a plurality of apertures therethrough. The apertures are wide enough to hold a single spring probe within the contactor block without the spring probe coming into contact with the contactor block. A retaining plate is coupled to the contactor block for holding the plurality of spring probes within the contactor block. The retaining plate has a raised portion thereon which limits the compression of the plurality of spring probes when a BGA device is placed in the spring probe contactor.
