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.
In general, this variable frequency vibration test is in conformity with IEC 60068-2-6 but, due to specific requirements of semiconductors, the clauses of this standard apply.
