Aluminum PCB




Aluminum PCB /Metal Core PCB / MCPCB (Enquiry pls send to )

Among all Metal core PCBs ( MCPCBs, known for their ability to provide effective thermal dissipation for electronic products), Aluminum PCBs is the most common type - the base material consists of aluminum core with standard FR4. It features a thermal clad layer that dissipates heat in a highly efficient manner, while cooling components and increasing the overall performance of the products. Currently, Aluminum Backed PCBs is regarded as the solution to high power and tight tolerance applications.


RAYMING as been offering aluminum PCB manufacturing services for over ten years. Our full feature aluminum circuit boards making capabilities and value-added options including Free DFM Check allow you to get high-quality aluminum PCBs done within budget. Aluminum PCBs printed by us are widely used for LED lighting, power equipment and automotive systems.


Metal Core PCB Materials and Thickness

The metal core of the thermal PCB can be aluminum (aluminum core PCB), copper (copper core 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.


RayMing Aluminum PCB Capacity :

RayMing can produce 1Layer, 2Layer ,4 Layer and 6layer Aluminum PCB . Multilayer aluminum PCB is mainly used by high power industria products ,Like outdoor Led screen .


Solder mask color : White , Black , We can provide super white color for Led PCB to improve the Led lumen.
