Aluminum PCB vs.Copper PCB, Advantages and disadvantages

Price Comparison
The copper PCB is the most pricey key ins steel core published circuit card. The thermal conductivity is far better compared to light weight aluminum PCB, this is usually utilized in high frequency circuit style.

Thermally Conductivity Comparison
The thermal conductivity of copper PCB is double greater than that of light weight aluminum PCB. The greater the thermally conductivity is, the greater transfer efficiency is as well as the far better thermal diffusivity is. Copper PCB needs a thick copper aluminum foil for its big present lugging capacity.

Innovation Practices
As copper PCB is required to have a great current carrying, a thick copper aluminum foil is required, usually, the density is 35μm ~ 280μm. A heavy copper PCB is produced in the same way by engraving thick copper dressed laminated board product. It used layering innovation and a combination of plating as well as etching to form the hefty copper features that results in trace sidewalls and also ignorable damaging. Copper PCB could be engraved sophisticated pattern as well as refined into a convex platform. The parts could attached on the system to accomplish the result of excellent grounding and also heat dissipation.
