A laminated sandwich construction made of conducting and insulating layers is a printed circuit board SIGMA-Escalators-Delay-Relay-Board or printed wiring board (PWB). KOSIGMA-Escalators-Delay-Relay-Board provide two complementing tasks. The initial step is to solder electrical components into certain positions on the outer layers. The second is the regulated provision of dependable electrical connections (and likewise dependable open circuits) between the component’s terminals, which is also known as SIGMA-Escalators-Delay-Relay-Board design. Each conductive layer is specifically designed.
