The circuit board is mainly composed of solder pads, vias, mounting holes, wires, components, connectors, fillers, electrical boundaries, etc. The main functions of each component are as follows:
Solder pad: A metal hole used for soldering pins of electronic components.
Through holes: There are metal through holes and non-metal through holes, where metal through holes are used to connect component pins between layers.
Installation hole: used to fix the circuit board.
Wire: An electrical network copper film used to connect component pins.
Connector: A component used for connecting circuit boards.
Fill: Copper coating used for ground wire networks can effectively reduce impedance.
Electrical boundary: used to determine the size of the circuit board, and all components on the circuit board must not exceed this boundary.
