Fr-4 PCB

Not all LED PCBs are created equal. The substrate material you choose—whether aluminum, copper, FR4, ceramic, flexible, or hybrid—fundamentally impacts your LED system’s thermal performance, cost, reliability, and lifespan. While aluminum LED PCBs dominate the market with their excellent price-to-performance ratio, copper core boards offer superior heat dissipation for high-power applications. FR4 remains the budget choice for low-power LEDs, while ceramic substrates provide unmatched reliability in extreme environments. This comprehensive guide breaks down all six LED PCB types, comparing thermal conductivity, cost, advantages, disadvantages, and ideal applications. Whether you’re designing automotive headlights, wearable LED products, or industrial lighting systems, understanding these material differences is essential for making the right choice for your specific requirements.
