Application of acoustic film volume resonators in micro shafts housings using a flip chip technique - -

摘要

A device comprises a chip, which contains a filter circuit. The filter is with the use of acoustic film implemented volume resonators. A housing contains the chip. The housing comprises a base portion, signal paths are contained in the base portion. Soldered connections fastening the chip to the base portion. The soldering connection pads on the chip is electrically connected to the signal paths in the base portion. The soldered connections no wire connections comprise and are used instead of the same.
