The high temperature embrittlement of module power supply refers to the natural environment of high temperature application of simulated commodities. The high and low temperature test time is usually 12-48 hours. There are two steps of high temperature embrittlement, which are set in high temperature natural environment and plug-in embrittlement. This is in high temperature natural environment, with the more extreme natural environment standard impact module power supply.
The power module is a power converter that can be directly installed on the printed circuit board. According to the conversion method, it is generally divided into AC to DC or DC to DC. With the development of technology, power capacity tends to be modular and miniaturized, so power module appears.
China has the largest consumption of steel and welding materials in the world. According to the relevant statistics in 2006, China's steel output is 420 million tons, accounting for 34% of the world's steel output, and the welding material output is about 3.2 million tons, about 50% of the world's welding material output.
