摘要

Electromagnetic interference (EMI) shields having attenuation interfaces are disclosed. A disclosed example EMI shield includes side walls defining sides of the EMI shield, and an attenuation interface to be placed into contact with a circuit board. The attenuation interface includes an inner perimeter having an EMI absorber and an outer perimeter having a metal backing to at least partially surround the EMI absorber.

說明書

Turning to FIG. 6K, the example attenuation interface 675 is depicted with an inner perimeter 676 surrounded by an outer perimeter 677.

The example of FIG. 6L depicts an example attenuation interface 680. In this example, an EMI absorber 682 is surrounded by and/or embedded within walls 684.

None of the features shown in conjunction with the examples of FIGS. 1-6L are limiting. Thus, any of the features of the examples shown in FIGS. 1-6L can be combined with any other feature(s).

FIG. 7 is a flowchart representative of an example method 700 to produce and/or assemble examples disclosed herein. The example method 700 begins as an EMI shield (e.g., the EMI shield 102) is being assembled and placed onto a circuit board (e.g., the circuit board 104) with an attenuation interface (e.g., the attenuation interface 101) being positioned therebetween. In this example, the circuit board is part of a computing device (e.g., the computing device 100).

At block 702, the shield is formed. The shield may be fabricated and/or cast (e.g., die cast). In some other examples, the shield is molded.
