"Intermediary Chongchou" name board circuit board are: PCB, PCB board, aluminum plate, high-frequency board, PCB, thin circuit boards, thin boards, printing (copper etching techniques) circuit boards. The circuit board mini, visualization, and optimization of fixed circuits for mass production with the electrical layout plays an important role in the composition of the board consists of pads, vias, mounting holes, wires, components, connectors, filling, electric border circuit board industry zones, the main function of each component are as follows: Pad: components for metal-hole solder pins. Vias: vias with metal and non-metal vias, wherein the metal pin through the hole for connecting components between the layers. Mounting holes: for fixing the circuit board. Wire: copper films for electrical network connection - pin. Connector: For the connection between the circuit board components. Filling: copper for the ground network, can effectively reduce impedance. Electrical border: means for determining the size of the circuit board, all components on the circuit board can not exceed the boundaries of the main board classification system classified into the following three categories: single-sided circuit board Single-Sided Boards we have just mentioned, in most the basic PCB, parts focused on one side of the wire is concentrated on the other side. Because the wire only in one side, so we call this PCB is called a single panel (Single-sided). Because there are many single-panel strict limitations in the design of the line (because only one side, and between the wiring alone can not cross paths must * around), so only the early use of such a circuit board only. Both sides of the double sided Double-Sided Boards have such a circuit board wiring. However, to use on both sides of the wire must be between the two sides have the proper electrical connection down. This circuit between the "bridge" called the pilot hole (via). Pilot hole in the PCB, full of holes or painted metal, which can be connected to the wire on both sides. Because the double-sided single-sided area than twice as big, and because the wiring can be interleaved with each other (you can go around the other side), it is more suitable for use in more complex than single-sided circuit. Multilayer [plywood] when more complex applications, the circuit may be arranged multilayer structure and pressed together, and between layers of cloth layers built through holes in the circuit in communication circuits.
