The shielding effect of nickel plating on copper foil in electromagnetic shielding materials

With the increasing complexity of modern electronic devices and electromagnetic environments, the demand for electromagnetic shielding materials continues to grow.Copper foil nickel platingAs a high-performance electromagnetic shielding material, it exhibits outstanding performance in the field of electromagnetic shielding due to its unique physical and chemical properties. This article will explore in detail the shielding effect of nickel plating on copper foil in electromagnetic shielding materials, and specifically mentionAdvanced Institute (Shenzhen) Technology Co., LtdContribution to nickel plating technology on copper foil.

1、 Overview of Copper Foil Nickel Plating Technology

Copper foil nickel plating is achieved through advanced electroplating technology, which uniformly coats a thin layer of nickel film on the surface of copper foil. This technology combines the high conductivity of copper foil with the excellent shielding performance of nickel, making nickel plating on copper foil an ideal choiceelectromagnetic shielding material.

2、 Electromagnetic shielding effect of nickel plating on copper foil

1. shielding effectiveness

Copper foil nickel plating performs well in electromagnetic shielding. According to experimental data, compared with pure copper foil of the same thickness, nickel plated copper foil has significantly improved shielding effectiveness in both low-frequency and high-frequency electromagnetic fields. In the low frequency range (such as 10kHz-1MHz), the shielding effectiveness of nickel plated copper foil can reach 60-80dB or more, while in the high frequency range (such as 1GHz-10GHz), its shielding effectiveness is as high as 90dB or more. This means that nickel plating on copper foil can effectively block the vast majority of electromagnetic waves, protecting electronic devices from electromagnetic interference.

2. frequency response

The shielding effect of nickel plating on copper foil exhibits good stability at different frequencies. Whether in low-frequency or high-frequency electromagnetic fields, copper foil nickel plating can maintain high shielding effectiveness, which enables it to perform excellent shielding in various electromagnetic environments.

3. The relationship between thickness and shielding effectiveness

The shielding effectiveness of nickel plating on copper foil is closely related to its thickness. Generally speaking, as the thickness of nickel plating on copper foil increases, its shielding effectiveness will also correspondingly improve. However, when the thickness increases to a certain extent, the improvement in shielding effectiveness will tend to flatten out. Therefore, in practical applications, it is necessary to choose the appropriate nickel plating thickness for copper foil according to specific needs to achieve the best shielding effect.
