Aluminum PCB is commonly used in LED lighting products. There are positive and negative sides, the white side is welded with LED pin, the other side presents the aluminum characters.  Generally it will be coated with thermal conductivity condensate and contacted with heat.

 

What is Aluminum PCB?

Aluminum substrate is a kind of metal-based CCL with good heat dissipation function. Generally, a single-sided board consists of a three-layer structure, namely a circuit layer (copper foil), an insulating layer and a metal base layer. For high-end use, there are also designs for the double-panel. It's structured of the circuit layer, insulation, aluminum, insulation, circuit layer. There are very few applications for the multi-layer board. It can be structured of ordinary multi-layer board and insulation, aluminum board. LED aluminum board is one kind of PCB, it also means printed circuit boards, just the circuit board material is aluminum alloy, before the general board material is glass fiber, but because LED generates heat obviously, LED lamps with the circuit board is generally Aluminum substrate, which can fast heat conduction.

 

Whats the advantage of Aluminum PCB?

Meet RoHs requirements; More adapted to SMT process; In the circuit design scheme it is extremely effective treatment for thermal diffusion, thereby reducing the module operating temperature, extending service life and improving power density and reliability; Reduce heat sink and other hardware (including thermal interface material) assembly, reduce product size, decrease hardware and assembly costs; optimize the combination of the power circuit and control circuit; Replace fragile ceramic substrates for better mechanical durability.

 

Whats the application of Aluminum PCB?

Aluminum substrate Usage: Power Hybrid IC (HIC).
