    Electroconductivity and electromagnetic shielding effect of copper plating poplar veneers

    • 摘要: 为了给电热式化学镀铜地热地板研究提供参考,对化学镀铜杨木单板的导电性与电磁屏蔽效能进行测试,分 析镀层厚度与吸收损耗、反射损耗、趋肤效应的关系。结果表明:镀铜杨木单板屏蔽效能主要以反射损耗为主,属 于反射型电磁屏蔽材料;表面电阻率随镀层厚度的增加呈减小趋势,横纹方向的表面电阻率是顺纹方向的3 倍左 右;频率越高,电磁波在镀铜层中传导时的趋肤深度越小,通过计算趋肤深度确定化学镀铜层的厚度,可以节省镀 铜时间并节约成本。

       

      Abstract: In order to provide a reference to electrothermal chemical copper plating geothermal floor, electroconductivity and electromagnetic shielding effect were test to analyze the relationship of adsorption loss、reflection loss and skin effect along with different plating thickness. The results were as following: The electromagnetic shielding effect of copper plating poplar wood veneers mainly resulted from the reflection loss, so it belonged to reflection loss materials. The surface resistivity of electroless copper plating poplar wood veneers decreased with the increase of plating thickness. The surface resistivity in inverse direction was 3 times of that in the transverse direction. The skin depth of electromagnetic wave that conducted in copper plating disminished with the increase of frequency, and the thickness of electroless copper plating could be determined by calculating the skin depth, which could save both the plating time and the plating cost.
