LED aluminum substrate and FR-4 glass fiber circuit board are both LED Printed Circuit Boards. To be different, only LED aluminum substrate and FR-4 glass fiber circuit board are compared. LED aluminum substrate is aluminum material with better thermal conductivity. Print the circuit on the plane and solder the electronic components to it.
The main purpose of LED Printed Circuit Boards using aluminum substrates is that they have good heat dissipation. High-power LEDs are used for the production of LED lighting because of the large heat generation. FR-4 glass fiber circuit board is a traditional electronic product circuit board. It has a wide range of applications due to its good insulation, corrosion resistance, pressure resistance and multi-layer printing.
The product quality of the LED aluminum substrate is mainly considered to be the material type, hardness, surface and thickness of the aluminum material, and it is also necessary to select a suitable model size according to the heat generation amount of the product. FR-4 glass fiber circuit board is a relatively mature product, and many of the LED display screens are made of FR-4 glass fiber circuit board.
