The working principle of the circuit board: to use the substrate insulating material to separate the conductive layer of copper foil, so that the current flows along predetermined paths in various components working amplification, damping, modulation, demodulation, coding, and other functions. There are now many PCB manufacturers available. One of the highly recommended is PCB Assembly China.
Circuit Board Principle
Structure. circuit board mainly by the pad, through hole, installation hole, wire, component, connector, filling, electric limit, etc. Common plate layers include single layer PCB, double layer PCB, and multilayer board (multi-layer PCB) three types. The main functions of each component are as follows:
- Solder plate: metal hole used for welding pin components.
- Top hole: there is metal over the hole and non-metal over the hole, where metal is used to connect the pin component between each layer.
- Mounting holes: to repair circuit boards.
- Conductor: Electric copper network film used to connect the component pins.
- Connectors: for circuit boards the relationship between components.
- Filling: Copper deposits for ground grids can effectively reduce impedance.
- Electrical limit: used to determine the size of the circuit board, all components on the circuit board cannot exceed
