摘要： 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.
