Problems solved by technology

Therefore, there is also a problem that, when an external force is applied to the antenna switch assembly due to impact such as falling, stress concentrates on the lamination surface between the first insulator circuit board and the second insulator circuit board and the solder fillet. At the end (near the laminated surface), cracks may occur in the laminated body, which may even cause a short circuit or disconnection of the circuit inside the laminated body

Abstract

The present invention provides an electronic component for use in a mobile communication apparatus and improved in joining strength to a print substrate, and also provides the mobile communication apparatus using this electronic part. Solution <??>In an electronic part formed by laminating first and second insulator substrates, an auxiliary electrode 8 is arranged in at least a portion of the laminating layer face on one side of the second insulator substrate in a portion of that laminating layer face which does not overlap the corresponding laminating layer face of the first insulator substrate.

Description

field of invention [0001] The present invention relates to an electronic component for a mobile communication device (portable phone, simple portable phone, etc.), such as an antenna switch assembly, a coupler, an antenna separation filter, an antenna duplexer, a filter, and the like. Background technique [0002] In recent years, mobile communication devices representing portable telephones and simple portable telephones (so-called PHS) have become thinner, lighter and more compact. Accordingly, miniaturization of electronic components used in mobile communication devices is also urgently required. For example, in an electronic part used by a mobile communication device, there is an antenna switch assembly for switching the antenna by receiving and transmitting signals (Japanese Patent Application Laid-Open No. 2001-127663, etc.). [0003] Previously, when mounting an antenna switch assembly on a printed circuit board, it was surface-mounted with solder (solder fillet) on ...
