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. Avec des dimensions de 140.45×93.72mm et un 2.0mm d'épaisseur, 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, Il offre une isolation électrique stable (constante diélectrique εr = 4,5) et résistance mécanique, Convient pour le fonctionnement dans des environnements à température et vibration modérées.
- 2-Empilement de calque:
- Top and bottom signal layers with ground/power planes implemented via copper pours for basic EMI suppression
- Split power domains (Par exemple, 5V/3.3V) separated by isolation traces to minimize cross-talk
- 1Oz (35μm) Épaisseur de cuivre:
- Supports moderate current loads (up to 8A per wide trace) for power-hungry components
- Copper pour areas on both layers reduce thermal hotspots and improve power distribution
- Masque de soudure LPI bleu:
- Distinctive color for easy visual inspection and component identification in dense layouts
- Chemical resistance against industrial contaminants and cleaning agents
- Finition de surface énig:
- 3–5 μm de couche de nickel pour la résistance à la corrosion
- 0.05–0,1 μm de couche d'or pour la soudabilité à long terme et la compatibilité de la liaison filaire
- Mixed SMT+DIP Capability:
- Smt: High-density placement of 0402 passive components, SOIC/SSOP ICs, and 0.5mm pitch QFP packages
