What is the difference between PCB aluminum substrate and copper substrate?

PCB copper substrate: PCB copper substrate is a very expensive material among metal substrates. Its thermal conductivity is much better than that of aluminum substrate. It is suitable for heat dissipation of high-frequency circuits and precision communication equipment with large high and low temperature changes. Generally, there are gold-plated copper substrates, silver-plated copper substrates, tin-sprayed copper substrates, and anti-oxidation copper substrates.

PCB aluminum substrate: The board made of aluminum-based material is called aluminum substrate, which has strong heat dissipation ability. This type of board is commonly used in LED lighting products. Aluminum substrate is a metal-based copper-clad board with good heat dissipation function. Generally, a single-sided board consists of three layers, namely circuit layer (copper), insulation layer and metal base layer.
