This 2-layer FR4 PCB addresses the needs of industrial control systems, automation modules, and power management applications requiring a balance of robust design and component integration. С размерами 140.45×93.72mm и 2.0ММ толщина, the board provides a stable platform for mounting microcontrollers, communication interfaces, and power components while maintaining mechanical rigidity for industrial environments. Constructed from FR4 material, it offers stable electrical insulation (Диэлектрическая постоянная εr = 4,5) and mechanical strength, suitable for operation in environments with moderate temperature and vibration.
- 2-Layer Stackup:
- Top and bottom signal layers with ground/power planes implemented via copper pours for basic EMI suppression
- Split power domains (НАПРИМЕР., 5V/3.3V) separated by isolation traces to minimize cross-talk
- 1Унция (35мкм) Толщина меди:
- Supports moderate current loads (до 8А на широкую трассу) for power-hungry components
- Copper pour areas on both layers reduce thermal hotspots and improve power distribution
- Blue LPI Solder Mask:
- Distinctive color for easy visual inspection and component identification in dense layouts
- Chemical resistance against industrial contaminants and cleaning agents
- Загадочная поверхность отделка:
- 3–5μm nickel layer for corrosion resistance
- 0.05–0.1μm gold layer for long-term solderability and wire bonding compatibility
- Mixed SMT+DIP Capability:
- Пост: High-density placement of 0402 пассивные компоненты, SOIC/SSOP ICs, and 0.5mm pitch QFP packages
- DIP: Through-hole mounting for rugged connectors (НАПРИМЕР., 0.1” headers, терминальные блоки) and relays
- Precision Fabrication:
- Laser direct imaging (LDI) for 100μm trace accuracy
- Electrolytic copper plating with uniform thickness verification
