Description

technical field [0001] The invention relates to the technical field of semiconductor production, in particular to semiconductor high-voltage insulation testing equipment. Background technique [0002] A semiconductor refers to a material whose conductivity at room temperature is between that of a conductor and an insulator. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, diodes are devices made of semiconductors. No matter from the perspective of technology or economic development, the importance of semiconductors is huge. The core units of most electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors. Common semiconductor materials include silicon, germanium, gallium arsenide, etc., and silicon is the most influential one in the application of various semiconductor material...

Problems solved by technology

[0003] The existing semiconductor high-voltage insulation test method is generally to manually place the chip in the test equipment, and then apply high-voltage electricity to the chip pins, and the test component detects whether there is leakage in the shell of the chip. Sorting, using this method, human error is likely to affect the accuracy of the test, and at the same time increases the labor cost, cannot fully automate the test, and the test efficiency is low
