Abstract
An adhesive reactive to ultraviolet rays is applied to an actuator mounting portion of a suspension. An electrical conducting material is applied to a conductor and the like of the actuator mounting portion. When the adhesive is irradiated with ultraviolet rays, the viscosity of the adhesive is increased. A piezoelectric element is placed on the adhesive the viscosity of which is increased. Thereafter, the adhesive and the electrical conducting material are heated, whereby the adhesive and the electrical conducting material are cured.
Claims8
A manufacturing method of a disk-drive suspension including actuator mounting portions on which piezoelectric elements are to be mounted comprising:
- applying an adhesive reactive to ultraviolet rays to the actuator mounting portion;
- irradiating the adhesive applied to the actuator mounting portion with ultraviolet rays to thereby increase the viscosity of the adhesive;
- arranging the piezoelectric element on the adhesive the viscosity of which is increased;
- heating the actuator mounting portion on which the piezoelectric element is arranged;
- and
- curing the adhesive by the heating to thereby fix the piezoelectric element to the actuator mounting portion.
A manufacturing apparatus of a disk-drive suspension including actuator mounting portions on which piezoelectric elements are to be mounted comprising:
- a transport shuttle which holds the disk-drive suspension;
- a drive mechanism which moves the transport shuttle;
- an adhesive feeding device which applies an adhesive reactive to ultraviolet rays to the actuator mounting portion;
- a light-irradiation device which irradiates the applied adhesive with ultraviolet rays to thereby increase the viscosity of the adhesive;
- an element feeding device which arranges the piezoelectric element on the adhesive the viscosity of which is increased;
- and
- a heating device which heats the actuator mounting portion on which the piezoelectric element is arranged to thereby cure the adhesive.
