Board Level Electromagnetic Interference (EMI) Shields With Increased Under-Shield Space

摘要

According to various aspects, exemplary embodiments are disclosed of EMI shields with increased under-shield space and/or greater component clearance for one or more components under the shield. In an exemplary embodiment, a shield generally includes one or more recessed portions along an inner surface of the cover. Dielectric material is along the inner surface of the cover within at least the one or more recessed portions. The one or more recessed portions may provide increased under-shield space and/or greater clearance for one or more components under the shield. The dielectric material may inhibit the one or more recessed portions of the shield from directly contacting and electrically shorting one or more components when the one or more components are under the shield. Also disclosed are exemplary embodiments of methods relating to making EMI shields and methods relating to providing shielding for one or more components on a substrate.

主权项

1. A shield suitable for use in providing electromagnetic interference (EMI) shielding for one or more components on a substrate, the shield comprising:
one or more recessed portions along an inner surface of the shield, whereby the one or more recessed portions may provide increased under-shield space and/or greater clearance for one or more components under the shield; and dielectric material along the inner surface of the shield within at least the one or more recessed portions, whereby the dielectric material may inhibit the one or more recessed portions from directly contacting and electrically shorting one or more components when the one or more components are under the shield.
