Abstract
A test head for an integrated circuit tester includes a main chassis defining a chamber that is open at the top. Tester modules are installed in the chamber, each tester module being removable as a unit from the chamber and including a tester module chassis, multiple pin electronics cards, and a tester module interface structure exposed at the top of the chamber. A test head interface structure is engageable with the tester module interface structures of the tester modules for connecting the tester module interface structures to a device interface unit.
