PURPOSE: A pressure reducing-type package socket is provided to stably contact a packet with socket pins by using an air pressure difference between the inside and the outside of the socket, thereby increasing efficiency of a packet test socket. CONSTITUTION: Side supports(2) fix a package(3). Socket pins(9) are used for contacting with package balls(4). A fixing plate(7) fixes the socket pins(9). Fixing screws(6) connect the fixing plate(7) with a lower plate(5). A pressure reducing motor(11) discharges an internal socket air. A tube(10) is connected with the pressure reducing motor(11). Air holes(13) are formed between the socket pins(9). An empty space(12) of a socket is connected under the air holes(13), so that the internal socket air is discharged outside through the pressure reducing motor(11) and the tube(10).
