Abstract: A test apparatus includes a first module configured to structurally support a target semiconductor device, and a second module reversibly attachable to the first module. The first module includes a first housing including one or more inner surfaces at least partially defining an inner space, a volume control unit configured to control a volume of the inner space, a mounting unit at least partially exposed to the inner space and configured to be exposed to the target semiconductor device, and a magnetic force control unit in the first housing. The second module includes a second housing, a test board in the second housing, and an attachable/detachable member in the second housing. The test board may be electrically connected to the target semiconductor device. The magnetic force control unit may control a magnetic property of the attachable/detachable member to cause the attachable/detachable member to attach/detach to/from the magnetic force control unit.
