Rolled double-sided nickel plated copper foil | Innovative material solution in high-end manufacturing field

In the current era of rapid development in electronic circuits and new energy industries, optimizing material properties has become a key factor driving technological breakthroughs.Rolled double-sided nickel plated copper foilAs a new type of composite material, it is gradually becoming an indispensable basic material in the high-end manufacturing field due to its unique physical and chemical properties. The rolled double-sided nickel plated copper foil produced by Advanced Institute Technology has achieved breakthrough improvements in material properties through precision processes, providing reliable technical support for industry applications.

Composite structure endows materials with dual advantages

The rolled double-sided nickel plated copper foil adopts a composite structure of copper substrate and nickel coating, which not only retains the high conductivity of copper material, but also endows the material with excellent corrosion resistance and wear resistance through the nickel layer. As a conductive core, the copper substrate has a conductivity of over 98% of the international standard value, ensuring high efficiency in signal transmission and energy conversion. The nickel coating is uniformly covered on the surface of the copper foil through electrochemical deposition technology, forming a dense protective barrier. Experimental data shows that the material has no corrosion phenomenon after continuous exposure for 720 hours in salt spray test, and its surface hardness reaches HV200 or above, significantly better than that of a single metal material.

Precision manufacturing process ensures quality stability

Advanced Institute of TechnologyThe production mode combines five roll continuous rolling technology with pulse electroplating process to achieve precise control of copper foil thickness and nickel layer uniformity. The rolling process uses multiple progressive rolling passes to control the thickness of copper foil within the range of 3-100 μ m, with a surface roughness Ra value below 0.2 μ m, meeting the processing requirements of high-density interconnect circuits. The electroplating process adopts pulse current control technology to control the thickness deviation of the nickel layer within ± 5%, avoiding the edge effect that is prone to occur in traditional DC electroplating. The entire production process implements the ISO 9001 quality management system, with 23 quality monitoring points set up from raw material testing to finished product delivery to ensure product batch stability.

Customized services meet diverse needs

Advanced Institute Technology provides customized thickness gradient services to meet the special requirements of different application scenarios. In the field of new energy, the 8 μ m ultra-thin copper foil developed for power battery current collectors can effectively alleviate stress deformation during battery charging and discharging by adjusting the rolling pass and annealing process, while maintaining a tensile strength of 0.3N/mm and increasing the elongation to 12%. In the field of high-frequency communication, customized 35 μ m thick copper foil reduces dielectric loss to below 0.002 by optimizing the nickel layer grain structure, meeting the strict requirements of 5G base stations for signal integrity. This modular production mode enables precise matching between material properties and application scenarios.

Typical Application Verification Material Value

After a certain communication equipment manufacturer adopted this material, the insertion loss value of their 5G filters decreased by 0.3dB, and the product qualification rate increased to 99.2%. In the field of new energy, a certain power battery enterprise applied customized copper foil, resulting in an 8% decrease in battery internal resistance and a cycle life exceeding 3000 times. These practices have shown that the optimization of material properties of rolled double-sided nickel plated copper foil can directly translate into improved performance and reduced manufacturing costs of end products. According to statistics, the use of this material can reduce the failure rate of electronic components by 40% and extend the maintenance cycle of new energy equipment by 30%.
