Contactor arrangement of an IC test handler, comprising: a contactor unit which has test contacts for contacting an IC in test and for temporarily pressing the IC against the test contacts, a plunger head, which has a recessed central region corresponding to the geometrical configuration of the IC, such that those surface of the IC which is adjacent to the upper surface of the plunger head does not touch the plunger head surface, and a contactor unit interface, which includes a vacuum suction system for actively attracting the IC to an IC contact surface of the contactor unit interface, that corresponds with an adjacent surface of the IC having IC device contacts and, thus, towards the test contacts of the contactor unit.
