In PCB, on different layer of board, consist via, which has two pads in corresponding position on different layers. As name suggests, in this type of PCB, a thin layer of conducting material, like copper is applied to both top and bottom sides of the board. These PCBs are used in low cost and bulk manufacturing application like calculators, radio, printers and the solid-state drive.ĭouble layer PCB is also known as double sided PCB. In this type of PCB, only one side of the PCB is used to connect different types of electrical or electronics components like resistor, capacitor, inductor, etc. A layer of solder mask is used to protect PCB against oxidation followed by silk screen to mark out all of the components on the PCB. Generally, copper is used as conducting material for PCB, because copper has very good conducting characteristic. One side of this PCB is coated with a layer of any conducting material. This type of PCB is simple and most used PCB because these PCBs are easy to design and manufacture. Out of these types of PCB, we have to choose the appropriate type of PCB according to our application.Ī single layer PCB is also known as single sided PCB. There are several types of PCB available for the circuit. It also used in many fields like medical devices, industrial machinery, automotive industries, lighting, etc. It can be found in many electronics devices like TV, Mobile, Digital camera, Computers parts like Graphic cards, Motherboard, etc. PCBs can be customised for any specifications to user requirements. PCB is used to provide electricity and connectivity between the components, by which it functions the way it was designed. In PCB, all components are connected without wires, all components are connected internally, so it will reduce the complexity of the overall circuit design. When PCB is not developed, at that time all components are connected with a wire which increases complexity and decreases reliability of the circuit, by this way we cannot make a very large circuit like motherboard. PCB is a copper laminated and non-conductive Printed Circuit Board, in which all electrical and electronic components are connected together in one common board with physical support for all components with base of board.
