Product: LED Printed Circuit Board (LED PCB)
Substrate Material:
General Use: FR-4 (universal for low-to-medium power).
High Heat Dissipation: Aluminum-based (MCPCB, thermal conductivity 1.0–5.0+ W/m·K, for high-power LEDs).
Ultra-High Performance: Ceramic (Al₂O₃, thermal conductivity 18–30 W/m·K, for extreme-power/harsh environments).
Copper Thickness: 1oz (35μm) – 3oz (105μm) (thicker copper for enhanced current carrying and heat dissipation).
Layers/Structure: Single-sided, double-sided, or multilayer (up to 6-layer + 1st-order HDI for dense wiring in small-pitch displays).
Surface Finish: ENIG (reliable soldering, long-term stability), OSP (eco-friendly, cost-effective), Immersion Silver, or lead-free HASL.
Key Performance Metrics:
Brightness: ≥800 cd/m² (adjustable, up to ≥1800 cd/m² for outdoor displays).
Refresh Rate: ≥3840 Hz (flicker-free for camera compatibility).
Pixel Failure Rate: ≤1/100,000 (ensures display reliability).
Special Design Features: Thermal vias for efficient heat transfer; voltage drop optimization for uniform brightness; optional “three-proof” (moisture, dust, salt-fog) coating for harsh environments.
Application: General lighting (bulbs, panels), LED displays (indoor/outdoor, small-pitch), automotive lighting (headlights, taillights), specialty lighting (plant growth, medical).
