This creation is a test machine structure improvement, especially a test machine structure that can avoid the position of the handle being easily changed, resulting in the lack of test signal interruption, thereby improving the reliability and test yield of the test machine.

The test machine of the general semiconductor industry, as shown in the first figure, is generally composed of a machine body 10 and a base 11 disposed on the machine body 10, and the base 11 is provided with a signal. The connection portion 12 is electrically connected to the machine body 10 so that the test signal of the machine body 10 can be transmitted to the signal connection portion 12. When the test operation is to be performed, please refer to the second reference. As shown, the operator will fix and mount a circuit board 20 to the base 11. This action is called docking. Usually, a structural reinforcement frame 22 (stiffener) is disposed around the circuit board 20. The structural reinforcement frame 22 can provide a better structural endurance to the circuit board 20 when docked, and the bottom surface of the circuit board 20 is provided with a signal-connected portion 21 corresponding to the signal connection portion 12, when the circuit board 20 is After the base 11 is docked, the signal of the circuit board 20 can be firmly connected to the signal connection portion 12 of the base 11 to achieve electrical connection, and the operator can take the device under test (DUT). The test is placed on the test area 23 of the circuit board 20.
