What is the operating principle of a circuit board?
Release time：2017-8-5Browse times：820
Is the use of plate insulating materials based on conductive layer separated from the surface of copper foil, the current along the preset route flow in various components such as power, amplification, attenuation, modulation, demodulation, encoding function etc..
Circuit board principle: structure
The circuit board mainly consists of pads, vias, mounting holes, wires, components, connectors, filling, electrical boundaries, etc.. The common lamellar structures include single layer Layer (Single, PCB), double deck (Double, Layer, PCB) and multilayer (Multi, Layer, PCB) three kinds. The main functions of each component are as follows:
Pad: metal hole used to weld component pins.
Vias: metal vias and non metal vias, wherein the metal hole for connection between each layer components pin.
Mounting hole: used to secure a circuit board.
Wire: an electrical network of copper film used to connect component pins.
Connector: used for connecting components between circuit boards.
Fill: Copper applied to ground wire networks to reduce impedance effectively.
Electrical boundaries: used to determine the size of the circuit board, all components on the circuit board can not exceed the boundary.
