FPC Material Requirements for Beauty Mask
● Soft board material: FPC substrate must have extremely low dimensional expansion and contraction rates to ensure stability
● Single and double panels: Dimensional fluctuations must be strictly controlled to improve circuit board reliability
● Rigid board material:
- Copper-clad FR-4 : Enhance mechanical strength and improve heat resistance
- PP (non-flowing) + Cu (PP Non-Flowing + Copper): Optimize lamination process and improve electrical performance
- RCC (non-flowing): Suitable for high-density flexible circuit boards
