The role and function of PCB in various electronic devices
- Pad: Provide mechanical support for fixing and assembling various electronic components such as integrated circuits.
- Wires: wires used to connect various electronic components, which can help circuit boards achieve wiring and electrical connection (signal transmission) or electrical insulation between components. Provide the required electrical characteristics.
- Green oil and silk screen: Provide solder mask graphics for automatic assembly, and provide identification characters and graphics for component insertion, inspection, and maintenance.
