  • Removable biasing board for automated testing of integrated circuits
    Patent number: 5519331
    Abstract: A "personality" card (bias adapter board) is employed to program power supply connections in a DUT (Device Under Test) fixture in an automated test environment. The DUT fixture is designed to provide access to power supply voltages from the automated test equipment (ATE) and to selected (configurable) pins of the device under test. Specific connections are established between designated power supply pins of the DUT and the ATE via the bias adapter card, thereby eliminating the need for a separate, expensive DUT board for each different DUT.
