Better Thermal conductivity Making Better Aluminum PCB

Aluminum PCB?are?metal-based,?copper-clad laminates?with a good?heat dissipation?function. Generally, a single Aluminium?metal core pcb?is composed of a?three-layer?structure: a??circuit layer?(copper foil), an insulating layer,?and a metal base layer. Aluminum PCB are commonly found in light-emitting?diode?(LED)?lighting products. There are two sides—the white side is for?soldering?the LED pins, and the other side is the natural color of aluminum.?

Generally, the thermal?conductive?paste will be applied to come into contact the?thermal conductive?part. Very few applications are?multi-layer aluminum PCB boards, which can mix-press ordinary?multi-layer?boards like FR-4?(glass-reinforced epoxy)?with insulating layers and aluminum core.

Aluminum PCB working principle

In addition, using aluminum substrates has?the following unique advantages:

1. Meets Restriction of Hazardous Substances (RoHS)?requirements;
2. More suitable for the?surface-mounted technology?(SMT)process;
3. In terms of?circuit design, thermal diffusion is extremely well treated, thereby reducing the operating temperature of the module, extending the service life, and improving the?power?density and reliability;
4. Reduces the assembly of?heat sinks?and other hardware (including thermal interface materials), reduces product volume, and reduces hardware and?assembly costs; optimizes?the combination of?power circuits?and control circuits; and
5. Replacesfragile?ceramic substrate?PCBs?to obtain better mechanical durability.
