What is an LED circuit board?

LED circuit board is the abbreviation of printed circuit board. LED aluminum substrate and FR-4 glass fiber circuit board both belong to PCB.

To talk about the difference, just compare the LED aluminum substrate and the FR-4 fiberglass circuit board. The LED aluminum substrate prints circuits on an aluminum plane with better thermal conductivity, and then welds electronic components to it. The main purpose of using aluminum substrate is that it has good heat dissipation. High-power LEDs generate relatively large heat, so most aluminum substrates are used in the production of LED lighting fixtures. FR-4 fiberglass circuit board is a traditional electronic product circuit board. It is widely used due to its good insulation, corrosion resistance, pressure resistance, multi-layer printing and other characteristics.

The main considerations for product quality of LED aluminum substrates are the material type, hardness, surface and thickness of the aluminum. The appropriate model size should also be selected based on the heat generation of the product. FR-4 fiberglass circuit board is a relatively mature product. Most of the LED displays use FR-4 fiberglass circuit board.
