Why should the vehicle voltage booster/buck power supply module be tested for aging(2)

Before the dc power supply module supply leaves the factory, it often goes through rigorous tests, including high and low temperature tests. The vehicle voltage booster/buck power supply module, which has been tested at high and low temperatures, can ensure the quality of the goods, reduce the probability of abnormality during the whole application process, and increase the service life. Although the dc power supply module supply just went out of the production line can be applied immediately, many of the products were found useless when they were in the hands of customers. This is because in the process of processing, only simple plug in detection is performed, and the plug in detection of long-term different natural environment is not performed.

A modular power supply is a power supply that can be directly mounted on a printed circuit board and can be used for application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field programmable gate arrays (FPGAs) and other Digital or analog loads provide power. Typically, such modules are referred to as load (POL) power supply systems or point-of-use power supply systems (PUPS). Due to the obvious advantages of the modular structure, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communications fields, as well as automotive electronics, aerospace, etc.

Most of the common faults of dc power supply module supply products occur in the early and middle late stages, and the manufacturer cannot accurately manipulate the middle and late stages, so only the early stage can be manipulated. Before the goods are handed over to the customer, the problem should be eliminated before delivery.

The key methods of dc power supply module supply embrittlement include load embrittlement at normal warm temperature and high and low temperature test with high temperature plug in. The common method is high temperature embrittlement. According to the high temperature embrittlement, the shortcomings or poor quality of commodity components can be exposed, thereby improving the reliability and credibility of the commodity.
