Abstract
Abstract A surface acoustic wave (SAW) device is mounteed in such a manner that its functional surface faces a base plate and a space is formed therebetween to avoid inferiority in device characteristics. Electrodes of the SAW device and bumps formed on electrodes at predetermined positions of the base plate are connected to each other by applying pressure and heat to secure electrical continuity. A peripheral surface of the SAW device is bonded to the base plate by an adhesive to seal the functional surface of the SAW device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A mounting device for an electronic component, comprising: a base plate having first electrodes at predetermined positions; bumps individually provided on said first electrodes; an electronic component having second electrodes each of which is directly and electrically connected to said bumps, and a functional surface which faces a top surface of said base plate; a space formed between said functional surface of said electronic component and said top surface of said base plate; and a viscous substances adhered to said electronic component and to said base plate in areas other than between said bumps and said electrodes, the dimensions of said space and the viscosity of said viscous substance being such that said viscous substance does not enter said space.
Claim 2
Dependent Claim
120 words
A mounting device for an electronic component, comprising: a base plate having first electrodes at predetermined positions; bumps individually provided on said first electrodes; an electronic component having second electrodes each of which is directly and electrically connected to said bumps, and a functional surface which faces a top surface of said base plate; a space formed between said functional surface of said electronic component and said top surface of said base plate; and a viscous substances adhered to said electronic component and to said base plate in areas other than between said bumps and said electrodes, the dimensions of said space and the viscosity of said viscous substance being such that said viscous substance does not enter said space.
Claim 3
Dependent Claim
36 words
A mounting device as claimed in claim 1, wherein said viscous substance is stuck to a periphery of said electronic component and to top surface of said base plate so as to hermetically seal said space.
Claim 4
Dependent Claim
19 words
A mounting device as claimed in claim 1, wherein said electronic component is a surface acoustic wave (SAW) device.
Claim 5
Dependent Claim
17 words

Claim 8
Dependent Claim
34 words
A mounting device as claimed in claim 1, wherein said second electrodes of said electronic component and said bumps are directly connected to each other as a result of applying pressure and heat thereto.
Claim 9
Dependent Claim
45 words
A mounting device as claimed in claim 1, wherein said base plate has a box-shape and said viscous substance is stuck to a top surface of said electronic component and to a side wall of said base plate so as to hermetically seal said space.
Claim 10
Dependent Claim
16 words
A mounting device as claimed in claim 8, wherein said electronic component is a SAW device.
Claim 11
Dependent Claim
