Black color single side aluminum PCB

Aluminum substrate is a metal substrate with good heat dissipation performance. Generally, a single layer consists of three layers: circuit board, copper foil, insulation layer, and substrate layer.
It is often seen in LED lighting products. There are two sides, the white side is welded with ED pins, and the other side is aluminum. Generally,
it is applied with thermal paste and contacts the heat-conducting parts. There are also ceramic substrates.

LED aluminum substrate, which means printed circuit board, but the circuit board material is aluminum alloy. In the past,
the general circuit board material was fiberglass, but because LED generates a lot of heat, the circuit board used in LED lamps is aluminum substrate, which has fast heat conduction.
The circuit board used in other equipment or electrical appliances is fiberglass board!

Working principle of aluminum-based PCB

The device is now installed on the surface of the substrate, and the heating element is conducted to the metal base through the insulation resistance,
And then the metal base conducts the heat away, thereby achieving heat dissipation of the device.

Production of Aluminum Based PCB

Compared with traditional FR-4, aluminum-based PCB can reduce thermal resistance to a minimum, so aluminum-based PCB has better conductivity than thick film ceramic circuits and excellent mechanical properties..

In addition, aluminum based PcB has the following unigue advantages:

Comply with ROHS requirements,

More suitable for SMT process, effectively handle thermal resistance in circuit design scheme, reduce module operating temperature, extend service life, improve power density and reliability. Reduce the assembly of hardware such as heat sinks, including bad interface materials, reduce product volume, reduce hardware and assembly costs, and optimize the combination of power circuits and control circuits

Replace fragile ceramic PCB substrates to obtain better mechanical durability
