Abstract:
A suction surface member is provided on an electronic component module including an electronic component base plate and surface mount device mounted on the electronic component base plate in order to provide a suction surface at a location that is substantially at the same level as or higher than that of an upper end of a transistor that is the tallest surface mount device. The suction head adheres to the suction surface to hold the electronic component module and the electronic component module is mounted on a motherboard defining the target board. Then a treatment is performed to prevent a situation in which an upper end of the suction surface member is higher than the upper end of the tallest surface mount device mounted on the electronic component base plate.

Abstract:
A high-frequency composite component for selectively switching a GSM-system signal path and a DCS-system signal path for a signal transmitted to or received from an antenna terminal by a diplexer. Transmission-side input terminals and reception-side balanced output terminals to be switched by high-frequency switches are included in the GSM and the DCS systems. Matching elements include inductors and capacitors that are inserted between the reception-side balanced output terminals and the output side of surface acoustic wave filters.
