1. Provide mechanical support for fixation and assembly of various electronic components, such as integrated circuits, to realize wiring and electrical connection or electrical insulation between various electronic components, such as integrated circuits, and provide required electrical characteristics.
2. Provide welding resistance graph for automatic welding, and provide identification characters and graphics for component installation, inspection and maintenance.
3. After the adoption of printing plate in electronic equipment, due to the consistency of the same kind of printing plate, the error of manual wiring is avoided, and the electronic components can be automatically inserted or pasted, automatically solder, and automatically detected, which ensures the quality of electronic products, improves labor productivity, reduces costs, and facilitates maintenance.
