This 2-layer FR4 PCB addresses the needs of industrial automation, sensor networks, and power management applications requiring a balance of compact design and robust performance. Avec des dimensions de 100×79.69mm et un 1.6mm d'épaisseur, the board offers a versatile platform for integrating microcontrollers, communication interfaces, and power components in a space-efficient 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 with minimal vibration.

Architecture de calque & Conception électrique

  • 2-Empilement de calque:
    • Top and bottom signal layers with ground/power planes implemented via copper pours, reducing electromagnetic interference (EMI) for basic signal integrity.
    • Split power domains (Par exemple, 5V/3.3V) separated by isolation traces to minimize cross-talk between analog and digital sections.
  • 1Oz (35μm) Épaisseur de cuivre:
    • Supports up to 8A current in power traces (≥1mm width) for motor drivers or solenoid valves.
    • Enables fine-line routing (ligne / espace minimum: 100μm/100μm) for low-speed signals (UART, I2C) and component density.

Industrial-Grade Features

  • Green LPI Solder Mask:
    • Standard industrial color for easy visual inspection during assembly and maintenance.
    • Chemical resistance against oils, coolants, and cleaning agents common in manufacturing environments.
  • Finition de surface énig:
    • 3–5μm nickel layer for corrosion protection; 0.05–0.1μm gold layer ensures reliable solderability for both SMT and DIP components, even after long-term storage.
  • Assemblage mixte SMT + DIP:
    • Smt: Accommodates 0402 passive components, SOIC/SSOP ICs, and 0.5mm pitch QFP packages for high-density integration.
    • TREMPER: Supports through-hole connectors (Par exemple, 0.1″ headers, bornes) and relays for robust field wiring in industrial setups.

Fabrication & Contrôle de qualité

  • Precision Fabrication:
    • Imagerie directe laser (LDI) for 100μm trace accuracy, ensuring consistent routing across the board.
    • Electrolytic copper plating with uniform thickness verification to maintain conductivity.
  • Tests complets:
    • 100% automated optical inspection (AOI) to verify solder mask coverage and silkscreen clarity.
    • Test de sonde volante pour la continuité électrique (≤0,1o) et isolement (≥ 100mΩ) to eliminate open/short circuits.
    • Tests de contrainte thermique (260°C reflow cycles) to ensure solder joint reliability during assembly.
  • Conformité des normes:
    • Meets IPC-6012 Class 2 standards for industrial electronics.
    • RoHS/REACH compliant for lead-free and hazardous substance restrictions.

Applications industrielles

  • Modules de capteurs industriels:
    Integrates temperature, humidité, or pressure sensors with analog signal conditioning and wireless communication (Par exemple, LoRa, BLE).
  • Motor Control Units:
    Drives low-voltage DC motors in conveyor systems, featuring PWM control, current limiting, and overheat protection.
  • Interfaces de communication:
    Permet la conversion du protocole (Par exemple, RS-485 to USB) for legacy industrial equipment integration with modern control systems.
  • Power Distribution Panels:
    Manages 24V DC power distribution to multiple loads, with circuit protection (fuses, TVS diodes) and status indication LEDs.
