PCB Concept

PCB concept
PCB (Printed Circuit Board), also known as printed circuit board and printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connection for electronic components. Because it is made using electronic printing, it is called a "printed" circuit board.
The role and function of PCB in various electronic devices
1. PCB pads: provide mechanical support for fixing and assembling various electronic components such as integrated circuits.
2. PCB wiring: to achieve the wiring and electrical connection (signal transmission) or electrical insulation between various electronic components such as integrated circuits. Provide the required electrical characteristics, such as characteristic impedance.
3. Green oil and silk screen: PCB provides solder mask graphics for automatic assembly, and provides identification characters and graphics for component insertion, inspection and maintenance.
