This 2-layer FR4 PCB balances space efficiency with robust performance for industrial control modules, sensor nodes, and low-power automation systems. 尺寸为 98.45×79.69mm 和一个 1.6毫米厚度, the board offers a versatile platform for integrating microcontrollers, 通讯接口, and power components in a compact form factor. Constructed from FR4 material, it ensures stable electrical insulation (介电常数εr=4.5) 和机械刚性, suitable for operation in moderate-temperature industrial environments.

层架构 & Electrical Design

  • 2-层堆叠:
    • Top and bottom signal layers with ground/power planes implemented via copper pours for basic EMI suppression.
    • Split power domains (例如, 5电压/3.3V) separated by isolation traces to minimize cross .
  • 1奥兹 (35微米) 铜厚:
    • Supports up to 8A current in power traces (≥1mm width) and fine-line routing (min line/space: 100μm/100μm) for signal integrity.
    • Copper pour areas on both layers reduce thermal hotspots in power-critical sections.

Industrial-Grade Features

  • 绿色 LPI 阻焊层:
    • Standard industrial color for easy visual inspection and component identification.
    • Chemical resistance against common industrial contaminants and cleaning agents.
  • 沉金表面处理:
    • 3–5μm nickel layer prevents corrosion; 0.05–0.1μm金层确保SMT和DIP元件的可靠焊点.
  • SMT+DIP Mixed Assembly:
    • 表面贴装技术: Accommodates 0402 无源元件, SOIC/SSOP ICs, and 0.5mm pitch QFP packages.
