Our copper-based heat sink products utilize advanced welding and lamination technology, ensuring a tight bond with the heat sink. This significantly improves the heat dissipation efficiency of the equipment and greatly reduces subsequent assembly and processing costs, making it a professional and efficient integrated copper-based heat sink solution.

Our Product Features
1. Single-sided double-layer copper foil. Directly receives heat from components, resulting in a shorter heat conduction path and a 30%-50% increase in heat dissipation area. Heat dissipation efficiency is 2-3 times higher than ordinary aluminum substrates with heat sinks.
2. Low thermal resistance. Overall thermal resistance can be as low as 0.1-0.5℃/W, effectively controlling the junction temperature of high-power devices and preventing light decay, shortened lifespan, or performance failure due to overheating.
3. Strong structural stability, adaptable to complex working environments. Warpage deformation is reduced by more than 60%.
4. Integrated heat sink design improves reliability. The copper substrate and heat sink are bonded together by welding, pressing, or thermal adhesive, resulting in a tight fit with no gaps or dead zones for heat conduction. Compared to solutions that add heat sinks later, this design offers stronger shock resistance.
5. High circuit design flexibility, adaptable to single-sided high-density layouts. The single-sided double-layer copper foil has clear functional partitions: the upper copper foil is the circuit layer, allowing for high-density circuitry and pad design, supporting SMT. The lower copper foil layer is a dedicated thermally conductive layer, not involved in circuit transmission, only responsible for heat dissipation, avoiding the limited circuit layout issues caused by "circuit and heat dissipation sharing a single copper layer".
6. Compatible with high-current scenarios. The double-layer copper foil has a stronger current-carrying capacity; a single square millimeter of copper foil can carry 5-8A of current, suitable for high-current circuit designs in new energy power modules and high-power drive power supplies, while reducing heat loss in the circuit.
7. Balanced cost and performance, with a cost-effectiveness superior to pure ceramic substrates. Furthermore, the processing technology is more mature.
8. Adaptable to high-power lighting. Improved beam uniformity and better heat dissipation uniformity avoid LED color temperature drift and uneven beam brightness caused by localized overheating.
9. Significantly extended lifespan: Through precise temperature control, the lifespan of high-power lighting products can be extended to over 50,000 hours, far exceeding that of ordinary aluminum substrate solutions.
