FR4 Precision PCB Manufacturing

6-Layer FR4 Industrial Control PCBA

Fully Hong Electronics Co., Ltd.

Product Information

Description

This 6-layer FR4 PCB is designed for industrial automation, power control, and communication equipment requiring extensive component integration and reliable performance. With dimensions of 289.00×145.00mm and a 1.6mm thickness, the board provides ample space for high-power devices, relays, and multiple connectors while maintaining mechanical rigidity via FR4 material (dielectric constant εr=4.5), suitable for long-term operation in environments with temperature fluctuations and vibration.

Layer Architecture & Electrical Design

• 6-Layer Stackup

  • 4 signal layers + 2 power/ground planes to isolate digital/analog signals and minimize EMI.
  • Inner power planes optimized for 24V industrial power distribution, with ground planes stitched via vias for enhanced shielding.

• 1OZ (35μm) Copper Thickness

  • Supports up to 8-10A current (wide traces) and reduces power loop impedance via copper pours.
  • Enables fine-pitch routing (min line/space: 75μm/75μm) for high-speed signals (Ethernet, CANopen).

Industrial-Grade Process Features

• Blue LPI Solder Mask

  • Enhances visual contrast for component identification in complex layouts.
  • Resists chemicals, oils, and coolants typical in industrial environments.

• ENIG Surface Finish

  • 3-5μm nickel layer for oxidation resistance; 0.05-0.1μm gold layer ensures long-term solderability and wire bonding compatibility.

• SMT+DIP Mixed Assembly

  • SMT: Supports 0201 passives, QFP/PGA ICs, and 0.5mm pitch BGAs.
  • DIP: Accommodates through-hole connectors (DB25, terminal blocks) and relays for field wiring.

Manufacturing & Quality Control

• High-Precision Fabrication

  • Laser Direct Imaging (LDI) for 75μm trace accuracy; electrolytic copper plating ensures uniform thickness.
  • Edge milling for smooth, burr-free surfaces suitable for panel mounting.

• Comprehensive Testing

  • 100% AOI for solder mask and silkscreen quality.
  • Flying probe testing for electrical continuity (≤0.1Ω) and isolation (≥100MΩ).
  • Vibration (5-500Hz, 2G) and thermal cycling (-40°C to +85°C, 500 cycles) to simulate industrial conditions.

• Standards Compliance

  • IPC-6012 Class 2, RoHS/REACH certified.

Industrial Applications

• PLC Control Panels: Integrates programmable logic controllers, I/O modules, and power management for factory automation.
• Power Monitoring Systems: Supports current/voltage sensors, RS485 communication, and relay outputs for switchgear monitoring.
• Industrial Communication Gateways: Enables protocol conversion (Modbus RTU to Ethernet) for smart factory networks.
• Renewable Energy Inverters: Manages solar/wind power conversion with large copper pours for thermal dissipation.
