Thermal shock testing involves exposing a package or product to extreme temperatures to determine its resistance to sudden changes in temperature. These tests are appropriate for products designed to withstand abrupt changes in temperature over a short period. This test might be desirable for products moving from a warm warehouse into a cold ambient temperature or for aircraft parts. The package or product undergoes a pre-determined number of cycles during which it is exposed to extremely high temperatures and then extremely low temperatures immediately afterwards. After the final cycle has been performed, the package or product is inspected for damage, loss of integrity and loss of performance or functionality. This testing detects latent product flaws by stimulating defects at the lowest level of assembly, before they reach your customer. This testing is designed for testing electrical, automotive, and military components.
