Cold and hot shock tests test chamber environmental effect of the product

Hot and cold impact test chamber for electrical and electronic zero electronics, automatic control parts, communications electronics, auto parts, metal composite materials, chemical materials, plastic manufacturing, such as manufacturing industry, national defense science and technology, aerospace, and industrial production, BGA, PCB base, electronic components integrated icIC, ceramics semiconductor devices and the change of the physical shape of textile material, test the raw material of high and low temperature continues to resist applied for and the product of chemical or physical damage to the heat bilges cold shrink productivity, hot and cold impact test chamber can be clearly the quality of products, from precision IC to heavy mechanical components, no need not its rational testing tools. The temperature of the hot and cold impact test box destructive available will cause a sharp change in gas temperature ( Refers to the elastic coefficient of temperature above 10 ℃ / min) Regional use of electronic products, also can be used as a geographical environment stress field choice ( ESS) Test, to stimulate the common problems. Temperature destructive can not exceed Imin conversion time for products, in turn, bare in the high temperature region and low temperature region, and the number of respiratory system must be according to the actual must establish) , is generally easy to indicate changes in temperature below extremism product rate if test specification does not exceed the product scheme design limit) Under the safety performance of the difficulty and the defects of irreversibility, and ESS test, according to GJB1032 usually change rate of high and low temperature of 5 c/min, when the temperature change rate above 10 ℃ / min, will use destructive instead of geographical environment temperature stress field of choice. Cold and hot shock tests test chamber environmental effect of the product plays a specific guidance throughout the process. Geographical environment is different, can lead to hot and cold impact test cases of this type of situation. Such as: part of the specimen or all the members were replaced specifications; Air density function decline and temperature system is constantly expanding; Work standard voltage of the power transformer and resistance value change is too big, cause the circuit is not stable, accompanied by following its temperature and the change of raw material, cause chemical reactions, lead to change the characteristics of the mechanical equipment, etc. The harm of products: hot and cold impact test chamber temperature because of its different lessens shrinkage index value of raw materials of products, in which lead to the test results between the characteristics and inspection is different also, Temperature is different, also can cause changes in the mechanical and electrical installation temperature characteristics of transformer, so as to harm the accuracy of test results; Sometimes parts of electrical conductor and the temperature of the conductor and an insulator can also make shift mechanical equipment. Hot and cold impact test cases to bridge sample tests, it is important to note whether the uniformity of temperature in the test sample test requirement is completely, make sure all the normal operating procedures. Experiment, the temperature in the cabinet evenness immediately hurt for accuracy of test results. As for six box wall surface heat transfer coefficient or line hole part of the heat transfer results in uneven temperature, or due to radioactive substances to known heat unevenly, and check the important direct cause, will damage the source for test uprooted, stable structures, safety coefficient and normal atmosphere. Remind each producer, the hot and cold impact test chamber structure and the box control parameters in the difficulties above must be handled carefully and precise measuring precision, can ensure that after using the clerk, efficient work. The above explanation is the hot and cold impact test chamber environmental effect test of products, hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
