The double-sided automotive aluminum substrate PCB is a special kind of printed circuit board. It is composed of a circuit layer, an insulating layer, an aluminum base, an insulating layer and a circuit layer, and it is a metal PCB circuit board with good heat dissipation function. This kind of PCB circuit board has wiring on both sides, but there should be appropriate circuit connections between the two sides.

The characteristics of the double-sided automotive aluminum substrate PCB include high thermal conductivity, high electrical performance, high reliability and environmental friendliness. It has good thermal conductivity and can quickly conduct heat out to ensure the stability and reliability of the circuit board. Meanwhile, it also has good electrical performance and can realize efficient circuit transmission and signal transmission. Besides, its high reliability and environmental friendliness also make it one of the key components for the development of the new energy industry.
