In order to ensure the higher reliability level of electronic products due to the thermal and thermal shock failures, as the product's moisture resistance improves, in addition to the relatively fixed temperature and humidity test, the requirements for high and low temperature impact tests are also increasing The more, the specific manifestations are:
1. In order to reduce costs, new materials and new processes are used;
2. The miniaturization of the whole machine makes the components more easily heated;
3. Components may be affected by severe thermal stress during processing, for example: when soldering;
4. Due to the requirements of product accuracy, components are continuously affected by greater thermal stress;
5. With the popularity of portable electronic products, the product usage environment has become more complex and demanding;
6. Reliability requirements and levels are getting higher and higher.
The cold and hot temperature impact of the high and low temperature impact test box is different from the ordinary humid and hot environment. It is to find the potential failure problems that are difficult to find under the normal temperature state through the cold and hot temperature impact. The only factors that determine the hot and cold temperature impact test are: test temperature range, exposure time, number of cycles, test sample weight and heat load.
