【产品】派克固美丽为消费电子应用,提供多种类型电磁屏蔽材料和产品
随着现代电子科技的不断持续发展,消费电子市场也保持着持续激增的状态,各种便携式电子产品开始逐步进入人们的生活当中。现在许多人出门已经不仅仅是一部手机,一台笔记本电脑,还会带上许多穿戴式电子产品,例如电话手表、智能手环、蓝牙耳机,等等。如此多的消费电子产品,势必会产生相当多的电磁干扰信号,而这些设备本身也需要屏蔽这些电磁干扰,以免造成设备故障或性能下降。PARKER CHOMERICS(派克固美丽)公司作为屏蔽领域的领先企业,为消费电子市场推荐了多种类型的电磁屏蔽材料和产品,本文对此做一下大致的品类介绍。
图1 派克固美丽的各种屏蔽垫圈、垫片产品类型
首先是各种类型的屏蔽垫圈、垫片产品,这是非常大的一个产品类型,包含有导电橡胶垫圈(CHO-SEAL®)、金属指形簧片(SPRING-LINE®)、原位成型垫圈(CHOFORM®)、金属化塑料垫片(Metalastic™)、定向金属丝垫圈(POLA®)、压缩金属网垫圈(SHIELDMESH™)和导电泡棉垫圈(SOFT-SHIELD®),实物如图1中所示。该类型产品应用广泛,可以用在各种连接器、接口、壳体和机构件的连接法兰中,起到电磁屏蔽功能和各种特殊应用效果。例如,导电橡胶可以起到水汽密封效果,金属指形簧片可以起到极佳的射频吸收和导电接地效果,等等。每一种垫圈类型还有很多型号和种类的区分,具体内容请参考世强官网和派克固美丽官网的相关介绍。
图2 导电层压板实物图
导电层压板是一种以金属层和绝缘层压制而成的平面屏蔽材料,实物如上图所示。这种产品可以用于既需要电磁屏蔽功能,又需要壳体绝缘的应用结构,例如液晶显示器周围的电磁屏蔽保护。该类型产品提供多种金属层材质和绝缘层材质,供客户选择定制,薄型垫片材料,易于折叠和模切成型,设计和使用上都十分方便灵活。
图3 CHO-FOIL®系列金属胶布和CHO-FABTM系列金属化织物胶布
导电胶布包含金属胶布CHO-FOIL®和金属化织物胶布CHO-FABTM两大系列。金属胶布的优点是导电性好、屏蔽效能高,并且能够提供清洁、出色的导电表面,这种胶布通常用在强调导电接地功能的应用中。金属化织物胶布的优点是柔韧性更好,应用上更加灵活,而且在电气性能也相当不错的前提下,价格更加经济,通常这种胶布的应用面更广一些。
图4 EMI屏蔽涂料
EMI屏蔽涂料也叫导电涂料(CHO-SHIELD®),主要由涂料基质添加金属微粒制成,也可以添加各种稳定剂和特殊添加剂,实现各种特殊特性,例如耐腐蚀、耐低温、防火阻燃,等等。涂料基质通常有环氧树脂、丙烯酸、聚氨酯和聚酯材质,金属微粒主要为纯银、镀银铜和纯镍材质。通过不同的配方,能够调制出不同性能和应用特点的产品。
图5 导电粘合剂
导电粘合剂(CHO-BOND®),顾名思义,主要作用是粘合,因为添加了金属微粒,所以具有导电性能和电磁屏蔽功能。该产品主要有环氧树脂粘合剂和硅胶粘合剂两大类型,金属微粒有纯银和镀银铜两种。与导电涂料相似,这也是通过配方和添加剂实现不同性能的一种产品。
图6 屏蔽保护窗实物图
屏蔽保护窗(WIN-SHIELD™),或者在许多消费电子设备中采用的薄型产品,我们通常称为屏蔽保护膜。在各种液晶显示屏和触摸屏上经常用到这类产品,可以提供具有各种特性的透视屏蔽保护膜。该类型产品通过在透光材料夹层中,加入嵌入层和屏蔽层,除了提供电磁屏蔽效果以外,还能提供各种实用特性,例如防窥屏的偏光效果,还有防眩光、防反光效果,等等。
