Product Details Data Sheet

Aluminum Based PCB is a kind of Metal Based PCB with good heat dissipation function. Generally, the single panel is composed of three layers: circuit layer (copper foil), insulation layer and metal base layer. Common in LED lighting products. There are positive and negative sides. The white side is welded with LED pins, and the other side is aluminum natural color. Generally, it will contact with the thermal conductive part after applying thermal paste. There are also ceramic PCB substrates and so on.


LED aluminum substrate PCB which is also the meaning of printed circuit board, but the material of circuit board is aluminum alloy. In the past, the material of our general circuit board is glass fiber, but because the LED heat is large, the circuit board used for LED lamps is generally aluminum substrate, which can conduct heat fast, and the circuit board for other equipment or electrical appliances is glass fiber board!

Working principle of Aluminum Based PCB

The surface of the power device is mounted on the circuit layer. The heat generated during the operation of the device is quickly transferred to the metal base through the insulation layer, and then the heat is transferred out by the metal base layer, so as to realize the heat dissipation of the device


Production of Aluminum Based PCB

Compared with the traditional FR-4, the aluminum based PCB can reduce the thermal resistance to the minimum, so that the aluminum based PCB has excellent thermal conductivity; compared with thick film ceramic circuit, it has excellent mechanical properties.


In addition, aluminum based PCB has the following unique advantages:

Meet ROHS requirements;

It is more suitable for SMT process;

In the circuit design scheme, the thermal diffusion is treated effectively to reduce the operating temperature of the module, prolong the service life, and improve the power density and reliability;

Reduce the assembly of radiator and other hardware (including thermal interface materials), reduce product volume, reduce hardware and assembly costs, optimize the combination of power circuit and control circuit;

Replace fragile ceramic PCB substrate to obtain better mechanical durability.
