Key Market Drivers:

• AI server demand surged 60% YoY in 2025, boosting HDI and 다층 PCB adoption.
• Automotive electronics penetration, especially in EVs, fuels high-reliability PCB growth.
• UGPCB’s 10-layer first-order PCB reduces signal loss by 42% using 2mil traces and laser microvia technology.

Technical Breakthroughs:

• Trace width/spacing as low as 1.5mil/1.5mil (업계 평균: 3밀).
• Impedance control tolerance of ±5% (Exceeds industry standards by 10%).

2. PCB Classification and Applications

2.1 Layer-Based Classification

Single-Layer PCBs: Simple designs (예를 들어, toys, power adapters).
Double-Layer PCBs: Uses vias for interconnection; ideal for routers and home appliances.
Multi-Layer PCBs (3+ 레이어): High-density designs for smartphones, automotive systems, and industrial controllers.

2.2 재료 & Process-Based Classification

견고한 PCB: FR-4 substrate for fixed-form devices (phones, TV).
유연한 PCB (FPC): Polyimide-based for bendable applications (screen cables, 웨어러블).
RIDID-FLEX PCB: Combines rigid and flexible sections for complex assemblies (drones, 의료기기).
