An ultrasonic etching method is effective to pretreatment of PVC plastic for plating without chemical pollution. After being etched for 60 min by 28‐kHz ultrasound, the improvement of adhesion strength of Cu–PVC can increase 13%, compared with that of chromic–sulphuric acid etching. The mechanism of adhesion improvement was studied by examination of weight loss, surface roughness, scanning electron microscopy, image analysis, and X‐ray photoelectron spectroscopy. © 1998 John Wiley & Sons, Inc.
