Patent ID: 7233158

Claim:
A method of testing a plurality of electrical components having a first plurality of electrical contacts, the method comprising: supporting a flexible membrane to cover a plurality of recesses within a housing, wherein the flexible membrane has a plurality of second electrical contacts positioned thereon and the flexible membrane and the plurality of recesses form a plurality of chambers, wherein the chambers are separated by a grid of walls, the grid defining a plurality of rows of chambers and a plurality of columns of chambers; aligning at least some of the plurality of first electrical contacts with at least some of the plurality of second electrical contacts; urging the flexible membrane toward the plurality of electrical components to effect an electrical connection between the aligned first and second electrical contacts by introducing a fluid into the plurality of chambers to direct the flexible membrane towards the plurality of electrical components; and energizing the plurality of electrical components through electrical connections to at least one of the first electrical contacts to perform a test sequence.
