High-temperature heat sink copper with nickel plating + high-temperature scale zero coating
FSC-HS CG
The issue with copper materials, which are widely used due to their thermal conductivity cost in various heat dissipation plates, heat sinks, and thermal compression terminal jigs, is performance degradation caused by the formation of oxide scale.
Various heat dissipation plates and heat sinks, as well as thermal compression terminal jigs, commonly use copper materials due to their thermal conductivity cost. The issue is the degradation of performance caused by the formation of oxidation scale, particularly in thermal problems that exceed 500°C, which cannot be addressed with aluminum. While copper is the next candidate due to its processability and price in terms of thermal conductivity, the oxidation scale that occurs at high temperatures poses problems for heat dissipation and contamination. We have now applied nickel plating to copper substrates and conducted our specialty treatment to prevent high-temperature oxidation scale with a transparent coating. This allows the thermal conductivity of copper to remain intact while making it usable at temperatures up to 900°C in air. We also offer coating treatment for the copper heat sinks you are currently using.
