Abstract
An EMI shielding apparatus has an outer peripheral wall extending around a combined area of predetermined shape and dimensions for enclosing at least two adjacent areas on a printed wiring board to be shielded from one another. A single transverse wall extends between opposing portions of the peripheral wall to divide the combined area into the two adjacent sub-areas to be shielded from one another. The single transverse wall is of single wall thickness, reducing the EMI shield footprint. The peripheral wall and transverse wall may be formed integrally as one frame, or from two or more adjacent sub-frames.
