Organization: IPC
Publication Date: 1 May 1997
Status: active
Page Count: 22
scope:

This technical report discusses the reasons and the test methods available for electrically induced failures on printed wiring board surfaces and sub-surfaces caused by a combination of voltage potential, electrical field, temperature, humidity, and contamination.

Solid State electromigration is discussed to differentiate from electrochemical migration phenomena. This document does not cover non-electrically-driven diffusion phenomena nor stress-induced whisker growth.
