PCB has the following functions in electronic devices.
(1) Provide a mechanical support for fixed and assembly of various electronic components such as integrated circuits to realize the wiring and electrical connection or electrical insulation of various electronic components such as integrated circuits to provide the required electrical characteristics.
(2) Provide welded graphics for automatic welding, and provide identification characters and graphics for components installation, inspection, and maintenance.
(3) After the electronic equipment uses the printed board, due to the consistency of the similar printed board, the errors of artificial wiring can be avoided, and the electronic component can be automatically inserted or pasted, automatic solder, and automatic detection. The quality has improved labor productivity, reduced costs, and facilitated maintenance.
(4) Provide the required electrical characteristics, characteristic impedance and electromagnetic compatible characteristics to the circuit in high -speed or high -frequency circuits.
(5) The printing board embedded in the passive component inside provides certain electrical functions, simplifies electronic installation procedures, and improves the reliability of the product.
(6) In large -scale and ultra -large -scale electronic packaging components, it provides effective chip carriers for the miniaturized chip packaging of electronic components
