ABSTRACT:
A shielded microstrip assembly (100)includes a substrate 102 having a first ground plane surface (106) and a second surface (206) which includes a transmission line (216). A plurality of solder balls (104) provide electrical interconnection for the ground plane and for the terminals (210) and (212) of transmission line (216). The microstrip assembly (100) is then inverted and attached using solder balls (104) to a carrier (302). The inverted microstrip assembly (100) of the present invention provides for improved shielding, while maintaining the high Q and other advantages associated with a microstrip.
