Semiconductor devices. Mechanical and climatic test methods - Vibration, variable frequency1 Scope This part of IEC 60749 describes a test to determine the effect of variable frequency vibration, within the specified frequency range, on internal structural elements. This is a destructive test. It is normally applicable to cavity type packages. NOTE This test method describes a swept sine test. A random vibration test is described in JEDEC document JESD 22 B103.
