According to the latest mobile phone reliability test standards issued by Huawei, in order to achieve the functions of mobile phones under extreme temperatures, a large part of them are temperature tests, including:

In the mobile communication module, due to the continuous increase of the transmission rate, the temperature of the working module will rise to a large extent when the module is working. In order to ensure the normal operation of the module, the temperature reliability test of the communication module needs to be carried out. The traditional verification method is difficult to meet the current test needs due to the slow temperature change, poor stability and inability to provide a rapidly changing temperature environment, The ThermoTST high and low temperature tester of Chengdu Cryogenic Technology Co., Ltd. solves the defects of traditional verification methods and provides fast high and low temperature impact capability as a necessary test method to assist in the production of communication modules.

During the production and quality inspection of communication module, it is required that the product of the production module assembly line should be subject to the temperature test within the range of - 50 ℃ to 90 ° C. Set different temperature values, simulate the transmission conditions of relevant products, and check whether the automatic frequency adjustment function of components involved in different temperatures is normal. Chengdu Zhongliang Cryogenic Technology recommends that the high and low temperature tester TS-560 test temperature range is - 70 to+225 ° C, the output gas flow is 4 to 18 scfm, and the temperature accuracy is ± 1 ℃. It can quickly conduct electrical performance test, failure analysis, reliability evaluation, etc. of electrical work.
