What is BS EN 60749-34 - Mechanical and climatic test methods for semiconductor devices about?

BS EN 60749-34 is the 34th part of a multi-series standard used for Semiconductor devices. this helps in manufacturing good quality Semiconductor devices. BS EN 60749-34 describes a test method used to determine the resistance of a semiconductor device to thermal and mechanical stresses due to cycling the power dissipation of the internal semiconductor die and internal connectors. This happens when low-voltage operating biases for forwarding conduction (load currents) are periodically applied and   removed, causing rapid changes in temperature. The power cycling test is intended to simulate typical applications in power electronics and is complementary to high temperature operating life (see IEC 60749-23). Exposure to this test may not induce the same failure mechanisms as exposure to air-to-air temperature cycling, or to the rapid change of temperature using the two-fluid-baths method. This test causes wear-out and is considered destructive.
