Embodiment approach

[0029] Exemplary embodiments of stretchable and / or flexible electromagnetic (EMI) shielding are disclosed herein, for example, including one or more stretchable and / or flexible portions (eg, stretchable and / or flexible shielding cover or cover Etc.) board level shielding (BLS). In various exemplary embodiments, the EMI shield includes a conductive shield cover or cover (broadly, a top surface or an upper surface). The shielding cover includes a stretchable and / or flexible material (for example, a stretchable and / or flexible composite material, etc.), so that the shielding cover is therefore stretchable and / or flexible. In some exemplary embodiments, a shielding cover may be applied and / or attached to a portion of the substrate (e.g., printed circuit board, flexible circuit, etc.) to cover one or more components on the substrate (e.g., circuit board mounting PCB electronic components, etc.). For example, the shielding cover may be flexed, stretched and / or shaped under heat, pr...

Abstract

EMI shields and related methods, electronic circuits, electronic devices. According to various aspects, exemplary embodiments of stretchable and / or flexible electromagnetic interference (EMI) shields are disclosed. In an exemplary embodiment, a shield generally includes a stretchable and / or flexible shield including a first side and a second side. One or more adhesive and / or dielectric layers are along at least the first side and / or the second side of the stretchable and / or flexible shielding layer.

Description

[0001] Cross references to related applications [0002] This application claims the priority and rights of U.S. Provisional Patent Application No. 62 / 188,173 filed on July 2, 2015 and U.S. Provisional Patent Application No. 62 / 326,933 filed on April 25, 2016. The entire disclosure of the aforementioned application is incorporated herein by reference. Technical field [0003] The present disclosure generally relates to stretchable and / or flexible electromagnetic interference (EMI) shields and related methods. Background technique [0004] This section provides background information related to the present disclosure, which is not necessarily prior art. [0005] A common problem in the operation of electronic devices is the generation of electromagnetic radiation in the electronic circuits of the device. This type of radiation can cause electromagnetic interference (EMI) or radio frequency interference (RFI), which may interfere with the operation of other electronic devices within a...
