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。
【选型】屏蔽效能超过90dB的高性能导电泡棉材料选型推荐
导电泡棉是一种常见的屏蔽材料,具有柔性好、压缩应力低、安装配合度高等优点,能够起到良好的EMI屏蔽和导电接地功能。美国派克固美丽公司,是一家世界知名的屏蔽材料生产厂家,在该公司官网的产品库中,推荐了多款导电泡棉材料。本文从中筛选了四款屏蔽效能全部超过90dB的高性能产品,做一下性能对比和应用优势介绍,希望对读者的选型工作有所帮助。
【产品】CHO-SEAL系列挤压镀镍石墨填充弹性体EMI垫圈
Parker Chomerics CHO-SEAL系列挤压镀镍石墨填充弹性体满足室内外应用的一系列EMI屏蔽和环境需求。所有这些材料在盐雾腐蚀应用中均具有出色的性能,并且可以满足流体浸入要求以及Underwriters Laboratories可燃性要求。镀镍石墨填料与硅橡胶或氟硅橡胶弹性体相结合,提供了一系列EMI垫片产品可供选择,可满足各种商业和军事应用需求。
根据环境和机械条件选择最合适屏蔽要求的EMI屏蔽垫片
最适合屏蔽要求的EMI垫片取决于被屏蔽设备的环境和机械考虑因素。此文旨在帮助工程师确定最佳屏蔽效果或接地的产品,其中包括金属厚度,材料类型,镀层,螺栓间距和接口尺寸等机械限制条件。
【经验】浅谈影响导电橡胶EMI垫圈屏蔽效能的综合因素
导电橡胶是一种常用的屏蔽应用材料,通常由金属或半导体导电颗粒填充橡胶基质制成。以导电橡胶为原材料制成的弹性EMI屏蔽垫圈,不仅具有良好的屏蔽效果,一般还具有水汽密封的功能。作为屏蔽应用来讲,屏蔽效能值一定是关键参数之一。那么,这个关键的屏蔽效能值,到底是由哪些因素决定的呢?由Parker Chomerics的屏蔽垫圈的例子可见综合因素对于屏蔽性能的决定性影响,主要有本身因素和配合结构因素。
