Claim 17:
18. An integrated circuit package assembly, comprising:
an integrated circuit chip package comprising a plurality of radio frequency coupling structures disposed on a first surface of the integrated circuit chip;
a carrier substrate comprising a plurality of waveguide openings which extend between first and second opposed surfaces of the carrier substrate and which are aligned, respectively, with the plurality of radio frequency coupling structures; and
a plurality of reflow solder waveguide shielding walls attaching the integrated circuit chip package to the carrier substrate and connected to a predetermined reference or ground voltage, where each reflow solder waveguide shielding wall is disposed around peripheral edges of a corresponding waveguide opening formed in the carrier substrate to at least substantially prevent signal leakage to and from any radio frequency signal transmitted through said corresponding waveguide opening.
