High and low temperature cycle testing (Storage) purposes
Goods after finish production is usually through a variety of different pipeline (shipping, air and land transportation) to deliver to the customer's hands, on the basis of the customer journey far and near, with the condition of the shipping PCBA products may experience a variety of severe high and low temperature differences, such as container in summer daytime insolation temperature may rise to 70 ° C, and winter night temperature can be as low as to 40 ° C below zero, so we have to test our PCBA products in advance, to ensure that at least can withstand such environment, can after customer received our PCBA products can also be used.
Moreover, some components are very sensitive to such temperature limits and may cause stress that reduces the function of PCBA products. This is a very important thing, in order to observe and ensure that our PCBA products will continue to operate under various temperature limits, it is necessary to perform environmental testing in a logical order.
(When the PCBA product is placed in the Environmental Chamber to perform functional testing, it is better to design the PCBA product to automatically test and record the time when the PCBA product is turned on, so that there is no need to worry about whether to perform the PCBA product testing in the retesting machine.)
