随着电子设备的越来越多,EMI问题日益严重,EMI屏蔽材料兴起并广泛应用在各领域。在通信,计算机,自动化,医疗等商用电子设备上选择最有效的EMI屏蔽材料时,通常可以考虑以下几种类型:导电橡胶金属簧片导电泡棉等。依据设备的不同需要,这几种类型的屏蔽材料可提供不同程度的电磁屏蔽,适合不同的形状和环境密封的要求。


在设计和选择EMI屏蔽材料时,应主要考虑以下因素:

  • 屏蔽性能,多数商用设备要求衰减量达到60~120dB;

  • 压缩量,多数商用设备考虑低闭合力设计,压缩量对导电橡胶的屏蔽效能有很大影响,导电橡胶可达到屏蔽效能范围较宽,而压缩量对金属簧片和导电泡棉的屏蔽效能影响不大;

  • 屏蔽材料形状;

  • 机械耐久性;

  • 对水、灰尘等外部环境的密封;

  • 屏蔽材料和接触金属介质间的电腐蚀性,避免导致电蚀的电流产生;

  • 成本,使用寿命,公差和安装方式(铆接式,粘接式等)。

 

下面来介绍这三种EMI材料:

1、导电橡胶

导电橡胶可提供较大范围的衰减量,并可提供环境和潮汽密封,适用于屏蔽效能要求较高的电子设备,掺入金属粒子的橡胶可经挤出或模压成多种形状和剖面。导电橡胶的填料可以是高导电性的银粒子至电性较低的碳粒子。屏蔽效能也是从高到低,我们可以根据屏蔽要求和价格来选择合适填料的导电橡胶。

2、金属簧片

金属簧片是机械耐久性要求高(如经常性的正交力或剪切力)时的最佳选择。金属簧片可以承受侧剪切力和正交力,而其他屏蔽材料只适用于正交力和垂直压缩的情况。金属簧片形状多样,可以起来屏蔽或接地作用,但不能提供环境密封。金属簧片可配合多种表面镀层提供,以与接触金属表面达到广泛的电化学相容性。

3、导电泡棉

导电泡棉通常用于无需要环境密封,机械耐久性要求低的设备上,一般导电泡棉的价格较低。导电泡棉具有良好的表面导电性,可以很容易用胶粘带固定在需屏蔽器件上。有不同的剖面形状、安装方法、UL等级及屏蔽效能的屏蔽材料可供选择。导电泡棉柔软易弯曲,在低闭合力的设备上使用时,在极小的压力下即可与壳体表面形成紧密接触。导电泡棉在不规则表面,边缘和弯角地方都可提供良好的接触。尤其适用于电子设备的箱体,例如门和其他开口处。

总的来说,以上三种EMI屏蔽材料的特点和区别可总结如下:

  • 导电橡胶可提供环境和潮汽密封,适用于屏蔽效能要求较高的电子设备;

  • 金属簧片是机械耐久性要求高(如经常性的正交力或剪切力)时的最佳选择;

  • 导电泡棉则适用于无需要环境密封,不规则表面、低闭合力、机械耐久性要求低的设备上。


目前世强有代理PARKER CHOMERICS(派克固美丽)和LAIRD(莱尔德科技),这两家的屏蔽材料处于世界顶尖水平,屏蔽材料品种齐全,性价比高,同时包括上述三种材料。

这两家的导电橡胶具有高耐腐蚀性,优良的抗压缩设定特性,连续使用年限长,导电性能好等优势;金属簧片机械强度好,弹性高,而且型号丰富、种类多样,能够适应各种应用需求和结构设计需求;导电泡棉可提供 X、Y 和 Z 轴导电性,压缩应力小、安装配合度高,耐温最高可达120℃的,吸湿特性最低仅为0.93%,且进行阻燃处理,可通过模切、冲孔、冲口等方式针对您的应用做定制,特别适用于使用常规垫圈时难以屏蔽的形状各异的应用。

如何正确地选择EMI屏蔽材料

随着电子设备的越来越多,EMI问题日益严重,EMI屏蔽材料兴起并广泛应用在各领域。在通信,计算机,自动化,医疗等商用电子设备上选择最有效的EMI屏蔽材料时,通常可以考虑以下几种类型:铍铜簧片,SMD接地弹片、导电泡棉,导电橡胶等。依据设备的不同需要,不同的屏蔽材料可提供不同程度的电磁屏蔽,适合不同的形状和环境密封的要求。

【经验】导电橡胶压缩性能详解及注意事项

导电橡胶的屏蔽性能不仅跟填充颗粒的多少和种类有关,而且和导电橡胶的压缩量也密切相关。只有在导电橡胶上施加适当的接触应力,使导电橡胶产生合适的压缩变形量,导电橡胶的屏蔽性能才能得以发挥,所以我们要明确压缩的两个概念及设计使用时需要注意的事项。本文以Laird的导电橡胶为例,建议在涉及过程中详细了解产品数据手册并按照建议设计开槽尺寸。

【选型】Laird 导电橡胶材料选型参考,三种橡胶基质,七种填充材料

从选型角度考虑,导电橡胶材料比较关键的指标有屏蔽效能、体积电阻率、适用温度范围、材料的硬度和强度等,主要由金属填充材料的种类、填充比例、制作工艺和橡胶基质(密度、工艺等)决定。Laird推荐的导电橡胶基质有三种,EPDM(三元乙丙橡胶)、硅橡胶和氟硅橡胶。以填充物材料为区别,将Laird推荐的19款导电橡胶材料分为7个大类,简单介绍一下各自的特点和应用优势,可作为选型参考。
