    摘要: A packaging assembly and methodology provide a PCB substrate with one or more waveguide apertures and a conductive pattern which includes a plurality of landing pads that are disposed around peripheral edges of each waveguide aperture and that are connected to one another by trace lines so that, upon attachment and reflow of solder balls to the plurality of landing pads, the solder balls reflow along the trace lines to form a fully closed solder waveguide shielding wall disposed around peripheral edges of the first waveguide aperture.
