Aluminum PCB

Aluminum PCB /Metal Core PCB / MCPCB 

Now many LED manufacturers are facing the problem of heat dissipation,aluminum PCB is the best solution, because the high thermal conductivity of aluminum, you can effectively export the internal heat, design PCB as far as possible close to the aluminum base, thereby reducing the potting part of the thermal resistance.(Enquiry pls send to Sales@vipcircuit.com )

Metal Core PCB Materials and Thickness

The metal core of the thermal PCB can be aluminum base , Cu-base PCB or a heavy copper PCB or a mixture of special alloys. The most common is an aluminum core PCB.

The thickness of metal cores in PCB base plates is typically 30 mil - 125 mil, but thicker and thinner plates are possible.

MCPCB copper foil thickness can be 1 - 10 oz.
