【产品】Laird推出带可拆卸拾放桥的表面贴装板级屏蔽罩,适合需要拆卸拾放桥的制造进程
LAIRD(莱尔德科技)是世界领先的导热材料、电磁屏蔽材料供应商,推出的一款带可拆卸拾放桥的表面贴装板级屏蔽罩。板级屏蔽材料结合了应用于BLS框架拾放桥的ReCovr连接机制,可在框架焊接到PCB后轻松、免工具地拆卸拾放桥。易于拆卸以及可靠和一致的分离力可实现屏蔽罩与拾放桥的自动分离。

改进后的拾放桥
莱尔德科技开发了一种新型的凸起拾放桥的屏蔽罩,此项技术获得了专利的保护。这种带有凸起可拆卸拾放桥的屏蔽罩有效减小了器件焊接后PCBA的总高度,见图2。从图中可以看出,器件焊接回流前2款产品的拾放桥是未拆卸的,屏蔽罩高度上形同,但是当焊接完成、拆掉拾放桥后,所采用的2种不同拾放桥的PCBA板总高度发生了变化,其中带有凸起拾放桥屏蔽罩的PCBA板的总高度有所降低。

图3为凸起拾放桥的屏蔽罩实物图,及将拾放桥和屏蔽罩分离后的效果图。

Laird板级屏蔽罩的产品特性:
·可拆卸的拾放桥
·最小高度:2.0mm(0.080")
·顶部法兰宽度:1.8mm(0.071")
·平坦度:部件尺寸相关,
·分离拉力(典型值)0.5-1.0磅
Laird板级屏蔽罩的应用领域:
非常适合需要或期望在回流焊后拆卸拾放桥的产品中,通常包括:
·制程检查需要
·产品维修返修需要
·能量交换有干涉时
·减小噪声/振动等问题

【成功案例】Laird表面贴装两片式板级硬角屏蔽罩解决车载以太网辐射超标问题
车载电子EMC法规中对导航频段的限值要求非常严苛,我们的一款车载音响产品中,车载以太网模块的辐射在俄罗斯导航系统频段超标严重,对噪声源头进行分析后决定采用屏蔽罩进行噪声抑制,通过对屏蔽罩形态和材料进行选择后,最后找Laird按笔者案例的实际情况定制了一款屏蔽罩,采用Laird设计的表面贴装两片式板级硬角屏蔽罩后,顺利的解决了问题。
