Aluminum PCB vs.Copper PCB, Benefits and drawbacks

Rate Comparison
The copper PCB is one of the most expensive enters metal core printed circuit card. The thermal conductivity is better than aluminum PCB, this is usually made use of in high regularity circuit style.

Thermally Conductivity Comparison
The thermal conductivity of copper PCB is double above that of aluminum PCB. The greater the thermally conductivity is, the higher transfer efficiency is and also the far better thermal diffusivity is. Copper PCB needs a thick copper foil for its big present lugging capability.

Modern technology Practices
As copper PCB is required to possess a terrific existing carrying, a thick copper aluminum foil is needed, generally, the thickness is 35μm ~ 280μm. A hefty copper PCB is generated in the same way by etching thick copper clad laminated board material. It used plating innovation and a combination of plating as well as etching to develop the hefty copper features that causes trace sidewalls and ignorable damaging. Copper PCB could be engraved sophisticated pattern as well as processed right into a convex system. The components could connected on the platform to achieve the result of excellent grounding and heat dissipation.
