Testing a new IC design is a critical step in the transition from product development to production. device-under-test (DUT) board is a key component of the test interface unit (see sidebar), and it serves as the interconnection between the test socket or contactor and the ATE test head. Because the DUT board is at the center of the test system, designing and producing one that delivers accurate and reliable test results require complete knowledge of: 1. The IC package to be tested. 2. The various test sockets or contactors that can be mounted on the board to interface with the IC package. 3. The various test heads to which the DUT board can connect. 4. The automated handling equipment used in the ATE system.
