This 2-layer FR4 PCB balances space efficiency with robust performance for industrial control modules, sensor nodes, and low-power automation systems. 치수와 함께 98.45×79.69mm 그리고 a 1.6MM 두께, the board offers a versatile platform for integrating microcontrollers, 통신 인터페이스, and power components in a compact form factor. Constructed from FR4 material, it ensures stable electrical insulation (유전 상수 εR = 4.5) 그리고 기계적 강성, suitable for operation in moderate-temperature industrial environments.
- 2-레이어 스택 업:
- Top and bottom signal layers with ground/power planes implemented via copper pours for basic EMI suppression.
- Split power domains (예를 들어, 5v/3.3v) separated by isolation traces to minimize cross .
- 1온스 (35μm) 구리 두께:
- Supports up to 8A current in power traces (≥1mm width) and fine-line routing (min line/space: 100µm/100mm) for signal integrity.
- Copper pour areas on both layers reduce thermal hotspots in power-critical sections.
- 녹색 LPI 솔더 마스크:
- Standard industrial color for easy visual inspection and component identification.
- Chemical resistance against common industrial contaminants and cleaning agents.
- ENIG 표면 마감:
- 3–5μm nickel layer prevents corrosion; 0.05–0.1μm 금 층은 SMT 및 딥 구성 요소 모두에 대한 안정적인 솔더 조인트.
- SMT+DIP Mixed Assembly:
- smt: Accommodates 0402 수동 구성 요소, SOIC/SSOP ICs, and 0.5mm pitch QFP packages.
- 담그다: Supports through-hole connectors (예를 들어, 0.1″ headers, 터미널 블록) and relays for field wiring.
- 정밀 제조:
- 레이저 직접 이미징 (LDI) for 100μm trace accuracy; electrolytic copper plating with uniform thickness verification.
