What is printed circuit board

What is printed circuit board, a lot of people have heard of the "PCB" the English abbreviation name. But what does it mean? In fact, very simple, that is, the printed circuit board. What is printed circuit board, it will appear almost in each kind of electronic equipment. If there are electronic components in a certain device, they are set on a PCB with different sizes. In addition to fixing all kinds of small parts, the main function of PCB is to provide the above parts of each other electrical connection.

     What is printed circuit board, with more and more complex electronic devices, the need for more and more parts, PCB on the line and parts are increasingly intensive. Bare boards (no parts on top) are often referred to as "printed wiring boards. The board itself is made of insulating material, which is not easy to bend. As can be seen on the surface of fine line material is copper foil, originally copper foil is covered on the board, and in the manufacturing process of part is etched away, the left part becomes network of thin lines the. These lines are called wires or wires, and are used to provide a circuit connection to the parts on the PCB.

     The color of the PCB is usually green or brown, which is the color of the solder resist. Is a protective layer of insulation, can protect the copper wire, but also can prevent parts to be welded to the wrong place. A screen printing surface can be printed on the solder resist layer. Usually printed on the top of the text and symbols (mostly white), in order to mark the location of the parts on the board. Screen printing surface is also known as the icon face.

     What is printed circuit board, printed circuit board design is based on the circuit schematic, to achieve the function of the circuit designer.
