1 Scope
This part of IEC 60749
details the procedures for the measurement of the characteristic properties of moisture
diffusivity and water solubility in organic materials used in the packaging of semiconductor
components.
These two material properties are important parameters for the effective reliability
performance of plastic packaged semiconductors after exposure to moisture and being
subjected to high-temperature solder reflow.
NOTE It is recommended that the moisture absorption parameters used in this standard be obtained from the material suppliers (such as the resin supplier).
