Shield Supporting Block

      Disclosed is a support block configured to snap into place at a
corner of a system (planar) board to provide structural support to a
flexible metal shield extending along a rear edge of the system
board.

      The Figure shows the flexible metal shield 10, a printed
circuit board 12, and the support block 14 in an exploded
relationship as viewed from the rear.  These components are assembled
to become portions of a system (planar) board assembly.  Shield 10
extends upward along a rear edge of circuit board 12.  While shield
10 generally surrounds, and is supported by, various connectors (not
shown) along the rear edge of circuit board 12, at the corner shown
in the Figure, such support does not exist.

      When the system board assembly is installed within the covers
(not shown) of a computing system, shield 10 fills a hole or gap in
the rear covers, with a number of spring tabs 16 making physical
contact with adjacent conductive cover surfaces (not shown).  In this
way, shield 10 is electrically connected to the covers, reducing
emissions of radio-frequency electromagnetic energy from the
computing system by surrounding various internal electronic circuits
with an electrically grounded shield.

      Support block 14 includes an "I"-shaped block 18 and a pair of
snap posts 20, which snap into holes 22 within circuit board 12.
When the elements shown in the figure are assembled, a surface 24 of
block 14 extends adjacent t...
