Trends in Printed Wiring Board Technology

Abstract

The printed wiring board plays the more important role in the mounting technology of smaller, lighter, thinner and more functional electronic equipment, being closely related with the advances of IC technology. The PWB's fundamental technology consists of the pattern formation by printing technology and the interconnection by plating. I describe here the PWB market, the higher density technology of electonic equipment, the copper clad laminates, the finner manufacturing technology of PWB and the future aspect.
