I. For more than three decades the use of printed copper paths on a substrate has been the key method of interconnecting electronic components to form electronic systems. During that time Printed Wiring Board (PWB) technology has evolved from very simple interconnections on a single side of a piece of phenolic board to very complex designs in which multiple layers of printed wiring are laminated together to form a three-dimensional interconnecting multilayer PWB.
