Problems solved by technology

[0003] In the prior art, two sets of independent devices are usually used to carry out the electric aging test and the parameter test respectively. In the specific operation, the photocoupler is generally installed on the electric aging platform to carry out the electric aging test, and the electric aging test After completion, remove the photocoupler and install it on the parameter detection device for parameter testing; since a large number of photocouplers need to be tested in the same batch, the disassembly operation of the photocoupler is very troublesome, the most important thing is , due to the independence of these two processes, during the electrical aging test, there is a lack of real-time parameter monitoring means, and it is impossible to obtain the operating parameters of the device during the electrical aging test in real time

Description

technical field [0001] The invention relates to a photoelectric coupler performance test technology, in particular to a test system capable of performing electrical aging tests and parameter tests on the photoelectric coupler. Background technique [0002] Optocoupler is a widely used device. After the optocoupler is manufactured, it is necessary to quantitatively evaluate the performance parameters of the optocoupler to screen out unqualified products and ensure product quality; the screening process is generally passed through electrical aging tests. and parameter testing two items to complete. [0003] In the prior art, two sets of independent devices are usually used to carry out the electric aging test and the parameter test respectively. In the specific operation, the photocoupler is generally installed on the electric aging platform to carry out the electric aging test, and the electric aging test After the completion, remove the photocoupler and install it on the pa...
