Patent ID: 6847220

Claim:
A method using a test fixture having a first pattern of contacts for burning-in and testing ball grid array semiconductor packages having a second pattern of contacts comprising: providing a burn-in and test fixture having a pattern of contacts having a first predetermined pattern corresponding to a second pattern of contacts of an unrelated semiconductor die; providing a plurality of ball grid array semiconductor packages connected to a substrate, each semiconductor package including: a portion of the substrate having a first surface and a second surface opposite the first surface and having an aperture through the portion of the substrate in communication with the first and second surfaces thereof; attaching a semiconductor device having an active surface with a plurality of bond pads thereon to one of the first and second surfaces of the substrate with the plurality of bond pads exposed within the aperture of the substrate; forming a plurality of ball grid array connective elements on one of the first surface and the second surface of the portion of the substrate; forming a plurality of test pads on a severable portion of the portion of the substrate, the plurality of test pads arranged in a first preselected pattern, the first preselected pattern of test pads having a predetermined pattern corresponding to the second pattern of contacts of the another unrelated semiconductor device for eliminating modification of the burn-in and test fixture for mating with a ball grid array semiconductor package; forming a plurality of substrate bond pads on one of the first surface and the second surface of the portion of the substrate; connecting selected bond pads of the plurality of bond pads on the active surface of the semiconductor device with selected substrate bond pads of the plurality of substrate bond pads using a plurality of bond wires extending therebetween; providing a first plurality of circuit traces selectively connecting the selected substrate bond pads of the plurality of substrate bond pads with selected connective elements of the plurality of ball grid array connective elements; providing a second plurality of circuit traces selectively connecting the selected connective elements of the plurality of ball grid array connective elements with selected test pads of the plurality of test pads; placing the at least one ball grid array semiconductor package in a burn-in and test apparatus having a plurality of test probes; contacting selected test probes of the plurality of test probes with the selected test pads of the plurality of test pads; burning-in and testing the at least one ball grid array semiconductor package by applying and routing electrical energy to the selected test pads of the plurality of test pads by way of the selected test probes of the plurality of test probes; and severing the portion of the substrate to form at least one ball grid array semiconductor package.
