[0002] The life test of PCBA transformer is a test activity designed to evaluate its long-term performance, reliability and durability under expected working conditions. Since transformers usually undertake key power conversion, signal isolation or coupling tasks in electronic equipment, their performance degradation or failure may cause failure of the entire system. Therefore, life testing of PCBA transformers is of great significance to ensure product quality, prevent early failure, reasonably plan maintenance cycles and optimize product design.
[0003] The existing detection method is to power on multiple PCBA transformers to make them run, and then record the running time of the PCBA transformers until they are damaged, so as to detect the average service life of the PCBA transformers. However, the working environment of PCBA transformers is different. The existing detection method cannot test the service life of PCBA transformers in different environments, and the detection data is single.
[0004] Therefore, a PCBA transformer life detection device has been developed that can simulate the service life of the transformer under different environments and improve the diversity and extensiveness of the transformer service life detection data. Utility Model Content
