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. 치수와 함께 100×79.69mm 그리고 a 1.6MM 두께, 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 (유전 상수 εR = 4.5) and mechanical rigidity, suitable for operation in moderate-temperature industrial environments with minimal vibration.

레이어 아키텍처 & Electrical Design

  • 2-레이어 스택 업:
    • Top and bottom signal layers with ground/power planes implemented via copper pours, reducing electromagnetic interference (에미) for basic signal integrity.
    • Split power domains (예를 들어, 5V/3.3V) separated by isolation traces to minimize cross-talk between analog and digital sections.
  • 1온스 (35μm) 구리 두께:
    • Supports up to 8A current in power traces (≥1mm width) for motor drivers or solenoid valves.
    • Enables fine-line routing (최소 선/공간: 100µm/100mm) for low-speed signals (UART, I2C) and component density.

Industrial-Grade Features

  • 녹색 LPI 솔더 마스크:
    • Standard industrial color for easy visual inspection during assembly and maintenance.
    • Chemical resistance against oils, 냉각제, and cleaning agents common in manufacturing environments.
  • ENIG 표면 마감:
    • 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.
  • SMT+DIP Mixed Assembly:
    • smt: Accommodates 0402 수동 구성 요소, SOIC/SSOP ICs, and 0.5mm pitch QFP packages for high-density integration.
    • DIP: Supports through-hole connectors (예를 들어, 0.1″ headers, 터미널 블록) and relays for robust field wiring in industrial setups.

조작 & 품질 관리

  • Precision Fabrication:
    • 레이저 직접 이미징 (LDI) for 100μm trace accuracy, ensuring consistent routing across the board.
    • Electrolytic copper plating with uniform thickness verification to maintain conductivity.
  • 포괄적 인 테스트:
    • 100% automated optical inspection (AOI) to verify solder mask coverage and silkscreen clarity.
    • Flying probe testing for electrical continuity (≤0.1o) 그리고 격리 (≥100mΩ) to eliminate open/short circuits.
    • 열 응력 테스트 (260° C 반사 사이클) to ensure solder joint reliability during assembly.
  • Standards Compliance:
    • Meets IPC-6012 Class 2 standards for industrial electronics.
    • ROHS/REACH는 무연 및 위험 물질 제한을 준수합니다.

산업 응용 분야

  • 산업 센서 모듈:
    Integrates temperature, 습기, or pressure sensors with analog signal conditioning and wireless communication (예를 들어, LoRa, BLE).
  • Motor Control Units:
    Drives low-voltage DC motors in conveyor systems, featuring PWM control, current limiting, and overheat protection.
  • 통신 인터페이스:
    Enables protocol conversion (예를 들어, 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.
