20100045313 | METHOD FOR TESTING INTEGRATED CIRCUITS MOUNTED ON A CARRIER - A method for testing integrated circuits mounted on a carrier includes the step of securing the carrier. The carrier is displaced into an operative position in which the integrated circuits are in physical and electrical communication with a diagnostic probe. Test signals are generated in test circuitry in electrical communication with the diagnostic probe and communicated to the integrated circuits with the diagnostic probe. The test signals are received at the test circuitry via the diagnostic probe. The test signals are made available to a controller via a communications link and an automated server and displayed with the controller. | 02-25-2010 |
