Many people may not know. In fact, it is very simple, is a printed circuit board (Printed circuit board, or PCB). PCB almost can be found in all electronic products, such as various types of home appliances, electrical appliances, computers, fans, etc., just open the shell can be seen PCB is circuit board.

PCB circuit boards are usually used to fix the electronic components and electrical connections on top of the various parts of each other, with the increasingly complex design of the appliance, the parts they need more and more the PCB top of the line parts more and more intensive. <SPAN title=裸板（上头没有零件）也常被称为 j="Bare board (top parts) is also often referred to as the " g="裸板（上头没有零件）也常被称为" ?

Substrate of the board itself is insulated, not easy to bend the material produced. The fine wiring material can be seen on the surface is a copper foil, the original copper foil is covered on the whole board, and part of the manufacturing process to be etched dispose left part into a mesh of fine lines . These lines are referred to as a wire (conductor pattern) or wiring, and used to provide a circuit connection of the parts on the PCB.
    Usually PCB circuit board color is green or brown, which is the color of the solder mask (solder mask). Insulating protective layer can protect the copper, and can also prevent the parts are welded to the not the right place. Will be printed on the surface of a layer of screen printing (silk screen) in the solder mask layer. Usually in it will be printed on the text and symbols (mostly white), to mark the location of each of the components on the board. Screen printing surface is also called the icon plane (Legend).
