1： The development of electronic components, the development of integrated circuits - IC, and the diverse use of semiconductor materials;

　　2： Electronic products pursue miniaturization, and the original perforated inserts cannot meet the requirements;

　　3： The revolution in electronic technology is indeed necessary to pursue international trends.

　　4： SMT processing has a more complete function in electronic products, and the integrated circuits currently used - ICs - no longer have perforated inserts, especially large-scale and highly integrated ICs that have to use surface mount technology;

　　5： PCB sampling, mass production, automation, and production enterprises strive to improve product quality and reduce production costs in order to improve their competitiveness and meet customer needs;
