<P>PROBLEM TO BE SOLVED: To reproducibly fix a holding tool to a horn when the holding tool is exchanged. <P>SOLUTION: An insertion hole 511 is formed at the other end side of the horn 51 with an ultrasonic vibrator fixed at one end concerning an electronic component mounting device. An annular tool fixing member 54 formed of a shape-memory alloy is arranged inside the insertion hole 511, to which the holding tool 53 is fitted by pressure. The abutments 543a, 543b of the tool fixing member 54 are abutted onto the inner side surface 512 of the insertion hole 511 by a shape restoring action with heat so as to fix the holding tool 53 to the horn 51. Consequently, the holding tool 53 is reproducibly fixed to the horn 51 in exchanging the tool 53. Thus, high quality joint is stably performed by fixedly keeping the vibration characteristic of the electronic component. <P>COPYRIGHT: (C)2007,JPO&INPIT |
