OEM 94V0 Printed Circuit Board LED Light Aluminum Led Bulb Light Pcb

Aluminum is the best choice for making the PCBs used in LED lights

The relatively low cost of aluminum compared to copper and steel, its light weight, excellent durability and its heat transferring capabilities are some of the reasons why this metal is increasingly being used in the manufacture of metal core PCBs for LED lights.

In recent times, metal core PCBs (MCPCBs) have gained popularity in the LED industry. The PCBs used in LED lighting require specific properties as the latter are temperature-sensitive. MCPCBs are today being used in high current LEDs and spotlights.

In the case of MCPCBs, the core or the base material is a metal instead of the traditional FR4/CEM1-3. In an FR4 board, heat remains stagnant if not transferred by a topical heat-sink. Another material for making PCBs, though less commonly used, is an epoxy. A PCB made of epoxy is considered less durable. However, in cases where thermal quality is not very important, FR4 or epoxy bases are more common as these are less expensive.

Commonly used metals for PCBs are aluminum, copper and steel alloys. Apart from being cheaper than copper, aluminum is known for its good heat transferring and dissipation abilities. However, copper is considered to be a better performer. Both normal steel and stainless steel are more rigid and have less thermal conductivity than aluminum and copper. The choice of the core depends on the desired output and application. In general, aluminum is laminated with copper.
