may include a shielding frame and a shielding lid carried thereby. A
printed circuit board may be within the shielding container. The
shielding frame may include a planar base with at least one opening
therein, a pair of opposing side walls integrally formed with the base
and extending upwardly therefrom, and a pair of opposing end walls
integrally formed with the base and extending upwardly therefrom. Also,
the shielding frame may include at least one intermediate partition wall
integrally formed with the base and extending upwardly therefrom to
define a plurality of container compartments. The partition wall may also
extend only partway between the opposing side walls to define at least
one partition end gap therewith.
