LED aluminum substrate plate difference with the ordinary PCB


 

LED aluminum substrate is one of printed circuit board. It’s a good thermal conductivity in the aluminum surface of the printed circuit, and then welded to the electronic components in the above.

PCB board is printed circuit board called for short,LED aluminum substrate and FR-4 fiberglass circuit boards are belong to PCB.The LED aluminum substrate compared to the FR-4 glass fiber circuit board, LED aluminum substrate is that it uses an aluminum-based materials, the thermal conductivity much better than the average FR4 materials. Because aluminum has a good heat dissipation to adapt to a lot of high-power electrical requirements.

At present, most of the aluminum plate for the production of LED lighting, and FR-4 glass fiber circuit board is the traditional electronic products circuit board, due to good insulation, corrosion resistance, compression, multi-layer printing, widely used in Communications, automotive, medical, industrial, security and other fields.

LED aluminum substrate product quality the main consideration is the aluminum material type, hardness, surface and thickness, but also with the product according to the heat to choose the appropriate model size.

The current field of lighting will be used in three circuit boards: for the production of led flexible strip called FPC circuit board; general lighting products using glass plate; lighting products are mostly used for aluminum plate.
