Introduction of item

1. YS_L4_001_001(GLASS PCB)

Glass PCB (Printed Circuit Board) uses glass as its primary material. It's gaining attention mainly in next-generation semiconductor 
packaging and high-performance display fields and has the following characteristics:

1. Excellent flatness and fine line resolution
2. High thermal stability and low coefficient of thermal expansion
3. Superior electrical properties & high mechanical strength
4. Transparency & high expectations of cost reduction

2. YS_L8_001_002(Specailty PCB)

Special PCBs refer to printed circuit boards that are designed and manufactured for specific applications or environments.The main 
types of special PCBs are as follows:

1. Aluminum/Metal Core PCB (MCPCB)
Uses a metal substrate (mainly aluminum) with excellent heat dissipation performance.
Applications: High-power LEDs, power modules, automotive lighting

2. Ceramic PCB
Uses ceramic materials such as Al₂O₃, AlN, or Si₃N₄.
Advantages: Excellent thermal conductivity, insulation and stability
Applications: Power electronics, RF/microwave, aerospace/military sectors
