OEM PCB LED Aluminum circuit boards Prototype LED PCB lighting
MCPCBs use a metal as the base, as metals are good conductors of heat. For this, manufacturers mostly use a base made of Copper, Aluminum, or Stainless-Steel. According to their physical properties, Copper has the best thermal conductivity of the three, but is also the most expensive. Aluminum also has a good thermal conductivity, but lower than that of Copper. Aluminum is also less expensive than Copper is. Although Stainless-Steel has the lowest thermal conductivity of the three, and is also the least expensive, Stainless-Steel is the most stable and rigid of the three metals.
MCPCBs are also known as Metal Core Boards, Metal Clad PCBs, Metal Backed PCBs, and Metal Base PCBs. The most popular MCPCB is the Aluminum Core PCB, also known as Aluminum PCB, and its popularity is mainly because of the most economic option Aluminum offers considering its thermal conductivity, rigidness, and cost.
