A set top terminal of the present invention includes: a tuner unit for receiving a signal from an external input terminal and selecting a signal of a predetermined frequency; a signal processing unit for decoding the selected signal; a modulation unit for outputting a signal obtained by decoding the selected signal from an external output terminal; a control unit for controlling the tuner unit, the signal processing unit and the modulation unit; a power source unit for supplying power to the tuner unit, the signal processing unit, the modulation unit and the control unit, respectively; and a main board on which the tuner unit, the signal processing unit, the modulation unit and the control unit are placed, wherein the tuner unit, the signal processing unit, the modulation unit, the control unit and the power source unit are separate individual bodies.

Set top terminal

A shielded high-frequency apparatus has a partitioned shielding case with a printed circuit board mounted therein. The partitioned shielding case is formed of a plurality of mutually intersecting shield plates which are attached within a frame to form a plurality of shield chambers. The partitioned shielding case is manufactured by first forming a solder resist film over the partitioned plate surfaces other than at specific end regions of the partition plates and over the frame internal surface other than at positions immediately adjacent to the end regions of the partition plates when the partitioned shielding case is assembled. The partition plates are then mounted in the frame, solder is next applied to the regions from which the solder resist film was omitted. Secure attachment of the partition plates and ease of implementation of automatic manufacture are attained, with reduced manufacturing costs.
