技术问答

81729是LAIRD的一款超薄金属织物导电带（如图1所示），厚度仅为0.043mm，具有出色的柔顺性、导电能力以及屏蔽能力，非常适合要经常弯折的应用，例如机柜、医疗设备和笔记本电脑，同时也可用于服务器、LCD电视和等离子电视、打印机等也需要EMI屏蔽的产品。

81729的结构图如图2所示，最上层的导电层由镍/铜金属化后的织物带组成，中间一层为具有导电能力的压敏胶，最下层为一防粘纸。得益于超薄的导电层和具有导电能力的压敏胶，81729具有出色的导电能力，其表面电阻率不足0.05Ω/sq，Z轴阻抗不超过0.05Ω。而且，此款采用可靠设计的导电带不仅具有出色的屏蔽能力，还具有很好的耐磨损和抗腐蚀能力。

81729是一款符合IEC-61249-2-21标准和RoHS标准的无卤素产品，可应用于0~80℃的环境之中，不过理想的应用温度是21℃~38℃，而且，将导电带粘到物体表面时，物体表面的温度不得低于10℃。另外，由于导电带的厚度很薄，因此压敏胶在一些严苛条件下有可能会渗透到导电带的表面，不过这并不影响产品的性能。

在交付的规格方面，81729的标准长度是每卷20m，而宽度可以根据用户的应用要求定制，最宽可以做到1000mm。

81729的主要特点：

·无卤素，符合IEC-61249-2-21标准和RoHS标准

·超薄镍/铜金属化后的织物带，厚度仅0.043mm

·配备导电压敏胶

·表面电阻率低于0.05Ω/sq，具有出色导电能力

·耐磨损，抗腐蚀，适合经常弯折的应用

81729的典型应用：

·机柜

·LCD电视和等离子电视

·医疗设备

·服务器

·打印机

·笔记本电脑
