PCB Assembly Services Introduction:
1. High density possible
Over the years, the high density of printed boards has been able to develop correspondingly with the improvement of integrated circuit integration and the advancement of mounting technology.
2. 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).
3. 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.
4. producibility
PCB adopts modern management, which can realize standardization, scale (quantization), and automatic production, so as to ensure the consistency of product quality.
