1. Electronic products are pursuing miniaturization. The previously used perforated plug-in components cannot be reduced.
2, electronic products are more complete, the integrated circuit (IC) used has no perforated components, especially large-scale, high-integration ICs, have to use surface patch components
3, product batch, production automation, the factory must produce high-quality products at low cost and high yield to meet customer needs and strengthen market competitiveness
4. Development of electronic components, development of integrated circuits (ICs), and diversified applications of semiconductor materials
5. The revolution of electronic technology is imperative and the result of internationalization of technology products.
