Copper MCPCB

SFX PCB's Copper MCPCBs can achieve thermal conductivity up to 400 W/MK, depending on the manufacturing process and configuration. This far exceeds aluminum PCBs (1–3 W/MK) and standard FR4 boards. For copper coin PCB variants, the embedded copper coin creates a near-direct heat path for localized extreme cooling in high-power components.

Copper foil thickness ranges from 1 oz to 10 oz for standard Copper Core PCBs. Heavy Copper PCBs extend this range from 2 oz up to 20 oz, with foil thicknesses of 105 µm, 140 µm, 175 µm and above. Standard board thicknesses available are 1mm, 1.2mm, 1.5mm, and 2mm.

Copper MCPCBs are widely used in LED lighting, automotive electronics (including EV components), aerospace and defense, military radar and weapon systems, medical devices, power supply and conversion equipment, 5G and wireless communications, industrial electronics, and nuclear and solar energy applications where reliable thermal management is critical.

SFX PCB offers multiple surface finish options for Copper MCPCBs including OSP (Organic Solderability Preservative), ENIG (Electroless Nickel Immersion Gold), and Immersion Tin. For Copper Coin PCBs, ENIG is the standard surface finish. The choice of surface finish affects solderability, shelf life, and performance in high-frequency applications.

Yes. Copper MCPCBs are available in single-sided, double-sided, multilayer, and high-frequency configurations. Heavy Copper PCBs support up to 24 layers for 3–4 oz copper weight in sample production. Multilayer configurations enable high-density circuit integration while maintaining the superior thermal management copper cores provide.

Yes. SFX PCB holds RoHS and REACH compliance certifications across its manufacturing facilities. Both copper and aluminum materials used in MCPCBs are recyclable and support environmentally responsible production. Halogen-free manufacturing options are also available.
