Abstract

The invention discloses a semiconductor device testing device in the technical field of semiconductor devices. The testing device comprises a testing machine which is used for testing the performanceof a semiconductor device; a probe fixing unit which is used for fixing a probe of the testing machine and driving the probe to move in the vertical direction; a bearing unit which is located under the probe fixing unit, and used for bearing the semiconductor device and driving the semiconductor device to move in the horizontal direction; and a PLC which is electrically connected with the testingmachine, the probe fixing unit and the bearing unit and controls the testing machine, the probe fixing unit and the bearing unit to work. According to the semiconductor device testing device, the testing machine is controlled by the PLC to test the semiconductor devices passing through the lower parts of the probes one by one; automatic testing of multiple packaged semiconductor devices on a largescale is achieved, the assembling and disassembling time during testing of the semiconductor devices is saved, the testing efficiency of the semiconductor devices on a large scale is improved, the labor cost is reduced, and the company operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of semiconductor devices, in particular to a semiconductor device testing device. Background technique [0002] With the development of society and the advancement of technology, semiconductor devices need to be electrically tested after production to ensure that they can meet the requirements. [0003] The current small-batch electrical performance verification of semiconductor devices is conducted by manually operating the testing machine to test the electrical performance of semiconductor devices. A single testing machine has a single test item and needs to cooperate with multiple types of testing machines to complete a series of electrical performance tests. Since the testing machine can only test A semiconductor device, so when faced with a large number of semiconductor devices to be tested, it is necessary to manually load and unload semiconductor devices repeatedly. The test efficiency is low, which l...
