Abstract:
1. A test chip socket adapted to be fixed to a tester substrate, the test chip socket comprising: a contact block fixable to the tester substrate; a test chip tray mounted to the contact block, the test chip tray having a convex part for positioning test target chips to a plurality of mount positions; a plurality of probes which are held by the contact block and contact the tester substrate and the plurality of test target chips, wherein each probe contacts with a respective terminal of a respective test target chip mounted to the mount position when the test chip tray mounting the plurality of the test target chips is fixed to the contact block; and a cover that covers the test target chips mounted on the tray and fixes the tray to the contact block, wherein the tray comprises piercing holes to which the probes are inserted, the piercing holes being formed in each of the plurality of mount positions, wherein the contact block comprises a base to which the probes are fixed, a table through which the probes pierce and on which the tray is placed, and a spring that supports the table at a position separated from the base, wherein the cover connects to the base in a condition that the table is pushed into the base, and wherein each of the probes contacts with the respective terminal of the respective test target chip exposed through the piercing hole when the cover connects with the base.
