This 2-layer FR4 PCB balances space efficiency with robust performance for industrial control modules, sensor nodes, and low-power automation systems. Avec des dimensions de 98.45×79.69mm et un 1.6mm d'épaisseur, the board offers a versatile platform for integrating microcontrollers, communication interfaces, and power components in a compact form factor. Constructed from FR4 material, it ensures stable electrical insulation (constante diélectrique εr = 4,5) and mechanical rigidity, suitable for operation in moderate-temperature industrial environments.

Architecture de calque & Conception électrique

  • 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 .
  • 1Oz (35μm) Épaisseur de cuivre:
    • Supports up to 8A current in power traces (≥1mm width) and fine-line routing (ligne min / espace: 100μm/100μm) for signal integrity.
    • Copper pour areas on both layers reduce thermal hotspots in power-critical sections.

Industrial-Grade Features

  • Green LPI Solder Mask:
    • Standard industrial color for easy visual inspection and component identification.
    • Chemical resistance against common industrial contaminants and cleaning agents.
  • Finition de surface énig:
    • 3–5μm nickel layer prevents corrosion; 0.05–0.1μm gold layer ensures reliable solder joints for both SMT and DIP components.
  • Assemblage mixte SMT + DIP:
    • Smt: Accommodates 0402 passive components, SOIC/SSOP ICs, and 0.5mm pitch QFP packages.
    • TREMPER: Supports through-hole connectors (Par exemple, 0.1″ headers, bornes) et relais pour le câblage sur le terrain.

Fabrication & Contrôle de qualité

  • Precision Fabrication:
    • Imagerie directe laser (LDI) for 100μm trace accuracy; electrolytic copper plating with uniform thickness verification.
    • V-cut scoring for optional panelization in high-volume orders.
  • Rigorous Testing:
    • 100% automated optical inspection (AOI) for solder mask coverage and silkscreen clarity.
    • Test de sonde volante pour la continuité électrique (≤0,1o) et isolement (≥ 100mΩ).
    • Tests de contrainte thermique (260°C reflow cycles) to ensure solder joint reliability.
  • Conformité des normes:
    • Classe IPC-6012 2 for industrial electronics; RoHS/REACH compliant for lead-free manufacturing.

Applications industrielles

  • Industrial Sensor Nodes:
    Integrates temperature/humidity sensors, analog-to-digital converters, and wireless modules (Zigbee/Bluetooth).
  • Motor Driver Modules:
    Manages low-voltage DC motors with PWM control, current sensing, and overheat protection.
  • Interfaces de communication:
    Enables RS-232/485 to USB conversion or simple protocol bridges for legacy industrial equipment.
  • Power Distribution Blocks:
    Distributes 24V DC to multiple loads with circuit protection and status indication.
