Electronic Component Sourcing Introduction:
1. High reliability
Through a series of technical means such as inspection, testing, and aging tests, the PCB can be guaranteed to work reliably for a long time (usually 20 years).
2. designability
Requirements for various properties of PCB (electrical, physical, chemical, mechanical, etc.) can be achieved through design standardization, normalization, etc. In this way, the design time is short and the efficiency is high.
