What is a PCB Board?

PCB board is the mother of electronic products. PCB board also known as a Printed circuit board (PCB) or Printed wire board(PWB) ,is a provider of electrical connections for electronic components.it is an electronic component that uses electronic printing to etch on the surface of the insulated and nonbinding copper-clad laminate, leaving a network of small circuits, so that various electronic components can form a predetermined circuit connection and achieve the relay transmission function between electronic components. Most electronic equipment and products need to be equipped PWB Board.
