Patent ID: 8228086

Claim:
A socket for testing a semiconductor chip, comprising: a base cover having a planar shape, with a coupling opening formed through a central portion of the base cover in a thickness direction; a conductive sheet fitted into the coupling opening of the base cover, the conductive sheet comprising: conductive parts provided in the conductive sheet in thickness directions, each of the conductive parts being made of conductive material; and an insulation part formed in an area of the conductive sheet outside the conductive parts, the insulation part being made of elastic insulation material; a plurality of upper plungers seated onto upper ends of the conductive parts of the conductive sheet, the upper plungers coming into contact with corresponding terminals of the semiconductor chip; a housing having insert holes at positions corresponding to the upper plungers, the housing fastening the upper plungers to the upper ends of the corresponding conductive parts of the conductive sheet such that upper ends of the upper plungers protrude outside through the insert holes of the housing; a plurality of lower plungers provided under lower ends of the conductive parts of the conductive sheet, the lower plungers coming into contact with corresponding terminals of a PCB (printed circuit board) to electrically connect the conductive parts to the PCB; and a support plate having holes at positions corresponding to the lower plungers, the support plate fastening the lower plungers to the lower ends of the corresponding conductive parts of the conductive sheet such that lower ends of the lower plungers protrude outside through the holes of the support plate.
