Withstand voltage test device for semiconductor production

Abstract

The invention relates to the technical field of semiconductor production, and especially relates to a withstand voltage test device for semiconductor production. The test device comprises a fixing frame, a protective device and a connecting device, the protective device is arranged on the outer side of the fixing frame, the top end of the right side of the protective device is fixedly connected with an indicator lamp and a controller which are arranged up and down, the connecting device is arranged on the right side of the fixing frame, and a first electric telescopic rod is fixedly connectedto the inside top end of the fixing frame. According to the invention, through the arrangement of a sponge brush and a first spring, the sponge brush is driven by a motor, a second electric telescopicrod is rotatably connected with a positioning plate, the first spring applies an elastic force to a sliding plate, and before the device is used for testing a semiconductor with a clean surface, a contact block can be cleaned, so that the phenomenon that a large amount of dirt is attached to the outer side of the contact block due to long-time use to influence the test is avoided, the phenomenonthat a semiconductor is crushed is also avoided, and the withstand voltage test precision of the semiconductor is ensured.

[0002] A semiconductor refers to a material whose conductivity is between that of a conductor and an insulator at room temperature. Semiconductors are widely used in radios, televisions, and temperature measurement. For example, diodes are devices made of semiconductors. Control, ranging from materials between insulators and conductors. With the continuous development of society, more and more semiconductors are produced, and there are more and more related equipment for semiconductor production. However, some semiconductor production uses withstand voltage test devices When in use, its conductive contacts are prone to dirt after long-term use, especially when dust and foreign matter are attached to the outside of the semiconductor, which will affect the accuracy of the semiconductor withstand voltage test, and it is easy to crush the semiconductor, and there is It will be affected by the humidity of the external air, and it will also affect the withstand voltage test of the semiconductor. Finally, it is inconvenient to connect and disassemble the connecting wire, and it is prone to electric shock, which threatens the safety of operators.
