Premium Copper Heat Sinks

Copper heat sinks are high-performance thermal solutions engineered for applications demanding extreme heat dissipation. With nearly double the thermal efficiency of aluminum, copper excels in managing hotspots in compact, high-power-density systems such as laser diodes, medical equipment, and EV power modules.
 
At Fecision, we engineer copper heat sinks for industries where thermal efficiency is non-negotiable. Combined with in-house CNC and plating facilities, we guarantee precision (±0.03mm) and rapid delivery – prototypes in 3-5 days, full production in 10-15 days.

Why Copper?

✔️Superior Heat Transfer – Ideal for hotspots exceeding 200W/cm².
✔️Compact Design – Achieve equivalent cooling performance with smaller footprints.
✔️Durability – Resistant to thermal cycling fatigue and oxidation (with nickel plating).
