A PCB - or Printed Circuit Board - is an essential component within various electronic assemblies. Used to connect other parts of the assembly together, PCBs consist of copper pathways that ensure conductivity between components, as well as other components that are later mounted onto the board to influence the circuit and electrical pathway. Once the required PCB has been designed, the copper pathways are laminated onto a substrate board, before undergoing various plating processes to amalgamate the different layers of the PCB together. Finally, the PCB undergoes silkscreening, during which time important information - such as part numbers - is printed onto the board for reference purposes. PCBs are the foundation of electronic assemblies and can be found within electronic consumer products and appliances, as well as industrial applications.
