Abstract:
1. A test head for an integrated circuit tester, the test head comprising: a main chassis defining a chamber having a top and a bottom, the chamber being open at the top, at least first and second tester modules installed in the chamber, each tester module comprising a tester module chassis, a plurality of pin electronics cards, and a tester module interface structure, a test head interface chassis, a support structure attached to the test head interface chassis and the main chassis and supporting the test head interface chassis for movement relative to the main chassis between first and second positions, and a test head interface structure mounted in the test head interface chassis and engageable with the tester module interface structures of the tester modules for connecting the tester module interface structures to a device interface unit, and wherein the tester module interface structure comprises a plurality of connectors, the test head interface structure comprises a plurality of circuit boards each having first and second opposite edges and a first connector attached to the circuit board at the first edge thereof, in the first position of the test head interface chassis the first connectors of the circuit boards of the interface structure engage respective connectors of the tester module interface structures, and in the second position of the test head interface chassis the test head interface chassis is spaced from the main chassis, the tester module interface structures are exposed at the top of the chamber, and each tester module is removable as a unit from the chamber.
