2.0mm Black Solder Heavy Copper PCB Circuit Board For Wall Lamp
2.0mm White Solder Heavy Copper PCB wall lamp led circuit board
Aluminum PCB vs.Copper PCB:
1. Price Comparison
The copper PCB is the most expensive types in metal core printed circuit board. The thermal conductivity is much better than aluminum PCB, this is usually used in high-frequency circuit design.
2. Thermally conductivity
The thermal conductivity of copper PCB is double higher than that of aluminum PCB. The higher the thermal conductivity is, the higher the transfer efficiency is and the better the thermal diffusivity is. Copper PCB needs a thick copper foil for its large current carrying capability.
3. Technology practices
As copper PCB is required to possess a great current carrying, a thick copper foil is needed, generally, the thickness is 35μm~280μm. A heavy copper PCB is produced in the same way by etching thick copper-clad laminated board material. It used plating technology and a combination of plating and etching to form the heavy copper features that result in trace sidewalls and ignorable undercutting. Copper PCB can be etched elaborate pattern and processed into a convex platform. The components can be attached to the platform to achieve the effect of excellent grounding and heat dissipation.
