Price Comparison
The copper PCB is one of the most expensive types in steel core printed motherboard. The thermal conductivity is much better compared to aluminum PCB, this is typically made use of in high frequency circuit design.
Thermally Conductivity Comparison
The thermal conductivity of copper PCB is double above that of aluminum PCB. The higher the thermally conductivity is, the greater transfer efficiency is as well as the much better thermal diffusivity is. Copper PCB needs a thick copper foil for its huge present bring capacity.
Technology Practices
As copper PCB is required to possess a terrific present carrying, a thick copper aluminum foil is required, normally, the thickness is 35μm ~ 280μm. A heavy copper PCB is generated in the same way by engraving thick copper clad laminated board product. It used plating modern technology as well as a combination of plating as well as etching to develop the hefty copper attributes that causes trace sidewalls and also ignorable damaging. Copper PCB can be etched fancy pattern and refined right into a convex system. The components could affixed on the platform to accomplish the result of outstanding grounding and heat dissipation.
