A contact apparatus includes a pusher having first and second surfaces, the first surface being connected to a pressure unit, stoppers protruding from edges of the second surface of the pusher away from the pressure unit, a pusher block having first and second surfaces facing each other, the first surface facing the pusher, and the second surface being connected to a semiconductor device, coupling members connecting the pusher to the pusher block, and a connector disposed between the pusher and the pusher block, at least part of a surface of the connector being circular, and the circular surface making a point contact with the pusher or the pusher block.

Contact apparatus and semiconductor test equipment using the same

A semiconductor package test apparatus having a test head and a test handler is provided. The semiconductor package test apparatus may include an insert in which a plurality of semiconductor packages are stacked and received in an offset fashion. Further, the semiconductor package test apparatus may include a plurality of sockets located adjacent to the insert and each of the inserts may have a plurality of socket pins. The sockets have different surface levels and are aligned with the semiconductor packages.

In one embodiment, a connector is made using a mixture of insulating silicone powder and conductive powder. The connector comprises a connector body formed from the insulating silicone powder and on or more preferably regularly arrayed conductive silicone members that are formed by migrating the conductive powder to a site of the connector corresponding to a solder ball of the semiconductor package. The conductive silicone member comprises a high-density conductive silicone part formed to be proximate an upper surface of the connector body and to protrude therefrom and a low-density conductive silicone part formed in substantial vertical alignment beneath the high-density conductive silicone part, the low-density conductive silicone part having a lower surface exposed from a lower surface of the connector body.
