摘要： The invention provides a solder alloy of Sn, Sb, Ag and Cu, wherein the Sb is about 1.0-3.0 wt %; the Ag is about 1.0 wt % or more and about 2.0 wt % or less; the Cu is about 1.0 wt % or less; and the remainder is Sn. The solder alloy has a comparatively low Young's modulus and sufficient tensile characteristics. Therefore, it resists peeling from the bonded electrode, etc., even though a heat stress is added. Also, a solder which has an excellent solderbility to metal phases such as Cu and Ni can be provided. Therefore, a solder alloy excellent in thermal shock resistance can be provided. The solder alloy may be used for soldering the inside of an electronic component.

摘要： A piezoelectric component has a substantially stronger connection between a substrate and a piezoelectric resonator and has improved electrical reliability. The piezoelectric resonator includes an insulating substrate having pattern electrodes disposed therein. A piezoelectric resonator capable of vibrating, for example in a longitudinal vibration mode is mounted on the substrate. A supporting member prepared separately as a pre-formed material member is bonded to the piezoelectric resonator at a nodal point of the resonator. A first flat surface of the supporting member is bonded to a vibrating electrode on the piezoelectric resonator by a first bonding and supporting material while a second flat surface of the supporting member is bonded to one of the pattern electrodes on the substrate by a second bonding and supporting material. The length of bonding between the piezoelectric resonator and the first bonding and supporting material along the longitudinal direction of the piezoelectric resonator is preferably set to about 25% or less of the overall length of the piezoelectric resonator. A central portion of another vibrating electrode of the piezoelectric resonator is connected to the other pattern electrode on the substrate by a conductor wire.

摘要： While suppressing that a vibration of a piezo-electric element propagates to a substrate by devising the composition of an electro-conductive support body, the piezoelectric resonant component which secures electroconductivity and can maintain a fall-proof shock property is provided. The piezoelectric resonant component has a substrate 20 on the top surface of which pattern electrodes 21 and 22 are formed, and on the lower surface of which it has electrodes 8 and 9. It has a piezoelectric element 1 using the length vibration on the substrate 20. Electro-conductive support bodies 10 and 11 are fixed to the length direction center section of the lower surface electrodes of the piezoelectric element 1. The connection fixation of these support bodies 10 and 11 to the pattern electrodes 21 and 22 of the substrate 20 is performed by electro-conductive adhesives 12 and 13. The electro-conductive support bodies 10 and 11 include an urethane resin which contains an electro-conductive filler, making the rate of content of the electro-conductive filler 75-85 wt %.
