Thermal Conductivity of Metals

Aluminum (w/m K) > 200

Copper  (w/m K) > 386




Carbon Steel is a poor thermal conductor, (w/m K)  ~ 30 to 50.

For heat sinks copper and aluminum are obvious choices due to their superior thermal properties and cost.

CNB-S1L


  • Multiple push pin locations for universal mounting on various board assembly (hole to hole distance: 53mm to 59mm)
  • Formed of pure copper to enhance thermal conductivity.
  • Excellent surface flatness minimizes the interface between heat source and heat sink.

PCB Fabricator - Search UL IQ Database

I picked up good tip today for identifying who fabricated a PCB.

Using the UL IQ Database and the UL Markings on the PCB.

















Search Underwriters Lab IQ Database for HF-4.
