Abstract
A test system, for testing a plurality of semiconductor devices, includes a carrying apparatus, an abutting apparatus and a pressing apparatus including a cover and a seat. The cover and the seat constitute a test chamber and a sealed auxiliary chamber. The carrying apparatus is disposed within the test chamber. Each semiconductor device is carried by one of a plurality of test sockets of the carrying apparatus. The abutting apparatus is disposed between the cover and the test sockets. The auxiliary chamber is extracted through at least one extraction hole, such that an air pressure in the auxiliary chamber is lowered to actuate the cover toward the seat and further to apply force to the abutting apparatus, and such that the abutting apparatus presses against the test sockets and the semiconductor devices to allow each test socket to electrically contact with the semiconductor device carried by said one test socket.
