PURPOSE:To execute a test exactly and efficiently, by mechanizing a clamping test, and giving a constant pressure. CONSTITUTION:On the top part of a supporting column 12 provided on the center part of a base 11, levers 13, 13' moving as one body are supported. One end of each lever 13, 13' comes into contact with a piston rod 14a of an air cylinder 14, and the other end comes into contact with rods 16, 16' for pressing a semiconductor device 2 installed to a semiconductor device installing part 15. Also, as for the cylinder, high-pressure air is further made to branch by a conduit 17, and it is operated by solenoid valves 18a, 18' and air pressure controllers 19a, 19a' which have been inserted in series into said valves, respectively. |
