A Printed Circuit Board is the acronym for Printed Circuit Boards, which are cards or circuit boards that are composed of a very thin flat metal or hard plastic-type board called an insulator. It is upon this that computer silicon chips and other similar electronic components are mounted. These boards are then used in electronic appliances like televisions, computers, washing machines, digital cameras, and so forth.

Components such as integrated circuits (chips), resistors, and capacitors can be soldered to the surface of the board (surface-mounted) or, more commonly, attached by inserting their connecting pins or wires into holes drilled in the board. The increased component density and complexity required by the electronics industry demands increasing use of multilayer PCBs which may have three, four, or more intermediate layers of copper conductor. PCBs include motherboards, expansion boards, and adaptors.

A PCB prototype that is produced by pcb manufacturer is the first circuit board that is invented for a new electronic device. By using this prototype in the electronic device, the inventor or pcb engineer can see if the prototype serves its purpose in the invention. Once the electronic device is made to function with the prototype, any mistakes that take place can be rectified in the prototype (some times mistakes are pin pointed by the pcb manufacturer). In this way, the Printed Circuit Board prototype or circuit board manufacturer saves the inventor of the electronic appliance lots of money (or it becomes cheap and cost effective), as any mistakes that may be present in the Printed Circuit Board will be pinpointed in PCB Prototype before the actual commercial manufacture of the Printed Circuit Board. Without having a pcb prototype, the model of a new invention will be of no use if its circuit board is not in good condition and up to requirements.

Electronic appliances are getting more and more technologically advanced by the day. This advancement is done through changes on its pcb prototype, Pcb Prototype is then tried on the appliance to see if the advancement is in right order. Using different materials of the boards also account for changes in the pcb prototype. You can use fiberglass, Teflon or cross-linked polystyrene for the Printed Circuit Boards manufacturing, and it is through the pcb prototype that you find out which material best fits your needs. Nowadays, new Printed Circuit Boards are in use in electronic appliances, thanks to the PCB prototypes.
