Aluminum PCB

PCB is also the meaning of printed circuit board, but the material of the circuit board is aluminum alloy. In the past, the material of our general circuit board was glass fiber, but because the LED heats up, the circuit board used in LED lamps is generally an aluminum substrate. At present, the commonly used PCB aluminum substrate material is metal-based copper clad laminate (mainly aluminum-based, copper-based, and a few are iron-based).

Metal aluminum-based copper clad laminate is a plate-shaped material made of electronic fiberglass cloth or other reinforced materials impregnated with resin, single resin, etc. as the insulating adhesive layer, one or both sides covered with copper foil and hot pressed. It is mainly used for processing and manufacturing PCB aluminum substrates, which are widely used in TVs, radios, computers, computers, mobile communications, LED lighting and other products.

PCB aluminum substrate material introduction:

As the substrate material in the manufacture of PCB aluminum substrate, the metal aluminum-based copper clad laminate mainly plays the role of interconnection, insulation and support for the PCB aluminum substrate,it has a great influence on the transmission speed, energy loss and characteristic impedance of the signal in the line.

The performance, quality, processability, manufacturing level, manufacturing cost, and long-term reliability and stability of PCB aluminum substrates depend to a large extent on metal aluminum-based copper clad laminates.
