What is the difference between LED aluminum substrate and FR-4 fiberglass circuit board (PCB board)

PCB board is the abbreviation of printed circuit board. LED aluminum substrate and FR-4 fiberglass circuit board are both PCBs. To say that they are different, just compare LED aluminum substrate and FR-4 fiberglass circuit board. LED aluminum substrate is heat conducting Print the circuit on the aluminum plane with better performance, and then solder the electronic components on it. The main purpose of using aluminum substrates is that they have good heat dissipation. High-power LEDs generate more heat, so most of the aluminum substrates are used in the production of LED lighting fixtures.
FR-4 fiberglass circuit board is a traditional electronic product circuit board. It has a wide range of applications due to its good insulation, corrosion resistance, compression resistance, and multi-layer printing.
The main consideration for the product quality of LED aluminum substrates is the material model, hardness, surface and thickness of the aluminum material, and the appropriate model size should be selected according to the calorific value of the product. FR-4 fiberglass circuit board is a relatively mature product, just choose the product with suitable quality.
