Classification of Printed Circuit Boards and Design Guidance
PCB, also known as printed circuit boards (also known as printed wiring board, or PWB), is a material employed in electronics and electrical technology for connecting electronics to each other in a controlled way. It’s an insulated sandwich consisting of insulating and conductor layers. Each of the conductive layers is created with an artistic pattern of planes, traces, and other elements (similar to wires on flat surfaces) made from one or more sheets of copper that are laminated on or between sheets of a non-conductive substrate.
The electrical components can be attached to conductive pads on the outer layer in a manner that is designed to accommodate terminals of the component, usually through soldering to connect them electrically and mechanically secure them to the substrate. Another process of manufacturing adds vias which are plated through holes that permit interconnections between layers.Read more
