Aluminum PCBs, also known as Metal Core PCBs (MCPCB) or Thermal Clad PCBs, represent the pinnacle of thermal management for high-density power electronics. At DuxPCB, we engineer these substrates using a specialized three-layer architecture: a circuit copper layer, a thermally conductive but electrically isolating dielectric layer, and a high-grade aluminum base (typically 5052 or 6061 alloys). Our manufacturing process focuses on optimizing the interface resistance between these layers to ensure rapid heat dissipation, vital for high-performance LED arrays, power converters, and motor drives where conventional FR-4 fails due to thermal saturation.
In addition to standard single-sided configurations, DuxPCB leads the industry in Hybrid Aluminum PCB and Multilayer Metal Core designs. We integrate specialized dielectric materials like TCB-4 and JQG05 to achieve thermal conductivities up to 5W/m.K. Our hybrid stackups allow engineers to combine the thermal benefits of aluminum with the high-frequency performance of Rogers or Megtron materials. This is critical for Class 3 aerospace and defense applications where thermal stability and signal integrity are non-negotiable. Our capabilities include complex blind and buried vias within the aluminum substrate to maximize routing density while maintaining structural integrity.

Q: What is the maximum breakdown voltage for your aluminum PCB dielectrics?
A: Depending on the material choice (e.g., TCB-4 or JQG05), we can achieve breakdown voltages exceeding 3000V AC, which is critical for industrial power supply and automotive inverter applications.
Q: Can DuxPCB handle heavy copper up to 8OZ on an aluminum base?
A: Yes. We are equipped for heavy copper processing, ensuring proper etching profiles and solder mask coverage for high-current paths in industrial motor controllers.
Q: Do you offer high-reflectivity solder masks for LED applications?
A: Absolutely. We utilize Taiyo PSR-4000 series (WT03/LEW3) to provide maximum light reflectivity and UV resistance for high-output lighting systems.
