Patent ID: 7859277

Claim:
A method of processing signals between a tester and a plurality of devices under test, the method comprising: mounting at least one multichip module directly on a probe card, each of the at least one multichip module having a plurality of micro-electromechanical switches connected between a first set of connectors and a second set of connectors, the mounting of the at least one multichip module directly on the probe card connecting the second set of connectors to a probe array of the probe card; connecting the first set of connectors to the tester by attaching the probe card, with the multichip modules mounted thereon, to the tester, wherein the first set of connectors are not connected to the tester when the probe card is not attached to the tester; connecting the plurality of devices under test to the probe array of the probe card; and selectively operating each of the plurality of micro-electromechanical switches to process the signals between individual ones of the first set of connectors to the tester and selected multiple ones of the second set of connectors to the plurality of devices under test.
