Light weight aluminum PCB vs.Copper PCB, Advantages and disadvantages
Price Comparison
The copper PCB is one of the most expensive enters metal core printed circuit board. The thermal conductivity is far better compared to aluminum PCB, this is generally utilized in high regularity circuit layout.
Thermally Conductivity Comparison
The thermal conductivity of copper PCB is double more than that of aluminum PCB. The greater the thermally conductivity is, the greater transfer efficiency is and also the much better thermal diffusivity is. Copper PCB requires a thick copper foil for its large present carrying capability.
Innovation Practices
As copper PCB is needed to have a great present transportation, a thick copper foil is needed, generally, the thickness is 35μm ~ 280μm. A heavy copper PCB is created in the same way by etching thick copper dressed laminated board product. It utilized plating technology and also a combination of plating and also etching to form the hefty copper features that results in trace sidewalls and also ignorable undercutting. Copper PCB could be etched fancy pattern as well as refined into a convex system. The components can affixed on the platform to achieve the effect of exceptional grounding and also heat dissipation.
