The aluminum based PCB is a metal-based copper clad plate with good heat dissipation function. Generally, the single-side board is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high-end use is designed as a double-side board, the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer boards, which can be made of ordinary multi-layer boards combined with an insulating layer and an aluminum base.

Often used in LED lighting products, there are two sides, the white side is soldered to the LED pin, and the other side is in the form of aluminum, generally the thermal conductive paste is applied and the heat conductive portion is contacted.


1. Compared with the traditional FR-4, the aluminum based PCB can minimize the thermal resistance and make the aluminum substrate have excellent thermal conductivity. Compared with the thick film ceramic circuit, its mechanical properties are extremely excellent.

2. Meet RoHs requirements.

3. More suitable for SMT process.

4. Extremely effective treatment of thermal diffusion in the circuit design, thereby reducing module operating temperature, extending service life, increasing power density and reliability.

5. Reduce the assembly of heat sinks and other hardware (including thermal interface materials), reduce product size, reduce hardware and assembly costs; optimize the combination of power and control circuits.

6. Replaces fragile ceramic substrates for better mechanical durability.

Storage conditions

Aluminum based PCB are generally stored in a dark, dry environment. Most aluminum based PCB is prone to moisture, yellowing and blackening. Generally, they should be used within 48 hours after opening the vacuum package.
