Abstract

PURPOSE:To enable discharge of heat control for ICs different in power under test at test time to be performed by making the IC socket body and the heat sink part replaceable and by replacing heat sink part only. CONSTITUTION:A heat sink plate 8 is installed on an IC 3 fitted with the side of a guide block 5 as a guide. The heat sink plate is pressed by a pressing member 9 that rotates centering on an axis 10 provided in a body 1. The IC 3 is held, and the pressing using the pressing member 9 is released. The heat sink plate 8 is removed from the body 1, and it is replaced with a heat sink plate 8 having a different discharge of heat efficiency. This structure enables control of discharge of heat for different powers to be performed only by replacing the heat sink plate 8 when ICs under test are the same type.
