1. An electromagnetic interference (EMI) shield having a single piece construction, comprising:
sidewalls configured for installation to a substrate generally about one or more electrical components on the substrate;
an upper surface integrally formed with the sidewalls;
a snap latch mechanism integrally defined by upper and lower portions of one or more of the sidewalls for releasably attaching a cover including the upper surface and the upper sidewall portions to the lower sidewall portions, the snap latch mechanism including:
a first interlocking member integrally defined by one or more of the upper sidewall portions, and downwardly depending relative to the upper surface;
a second interlocking member integrally defined by one or more of the lower sidewall portions, and upwardly protruding relative to the upper surface of the cover; and
an opening to accommodate movement of the first interlocking member inwardly relative to the opening, thereby allowing continued respective upward or downward movement of the first interlocking member relative to the second interlocking member for engaging or disengaging the snap latch mechanism;
whereby disengagement of the snap latch mechanism allows the cover to be completely separated from the lower sidewall portions of the shield; and
whereby the cover is reattachable to the lower sidewall portions of the shield by engagement of the snap latch mechanism.
