Abstract
The space charge profiles of a metal-base printed wiring board were observed. The space charge of an aged sample formed the same distribution as that of copper migration inside the insulation layer. It is found that space charge observation by means of the pulsed electroacoustic method is useful for investigating the aging phenomena of a printed wiring board
