Claims
- 1. A method for manufacturing a magnetic head suspension assembly comprising the steps of:forming a plurality of flexure, pieces coupled with each other and lying flat over their combined surfaces, each of said flexure pieces being provided with a conductive connection pattern; mounting, head IC chips on respective ones of the substantially flat flexure pieces, said mounting being executed before fixing of said flexure pieces to load beams; and separating said flexure pieces with the head IC chips into individual pieces.
- 2. The method as claimed in claim 1, wherein said method further comprises a step of checking electrical characteristics of said mounted head IC chips, said check being executed before fixing of said flexure pieces to the load beams.
- 3. The method as claimed in claim 1, wherein said method further comprises a step of mounting sliders with magnetic head elements on the separated flexure pieces.
- 4. The method as claimed in claim 1, wherein said head IC chip mounting step comprises a step of mounting the head IC chips on the respective flexure pieces by flip chip bonding process.

- 6. The method as claimed in claim 3, wherein each of said flexure pieces has a tongue portion for fixing the slider, and wherein said method further comprises a step of bending the tongue portions of the respective flexure pieces so as to adjust static attitude of the sliders to be attached, said tongue portion bending step being executed before said head IC chips are mounted.
- 7. The method as claimed in claim 3, wherein each of said flexure pieces has a tongue portion for fixing the slider, and wherein said method further comprises a step of bending the tongue portions of the respective flexure pieces so as to adjust static attitude of the sliders to be attached, said tongue portion bending step being executed after said head IC chips are mounted but before said coupled flexure pieces are separated into individual pieces.
- 8. The method as claimed in claim 3, wherein each of said flexure pieces has a tongue portion for fixing the slider, and wherein said method further comprises a step of bending the tongue portions of the respective flexure pieces so as to adjust static attitude of the sliders to be attached, said tongue portion bending step being executed after said coupled flexure pieces are separated into individual pieces.
- 9. The method as claimed in claim 1, wherein said method further comprises a step of fixing a load beam to each of the separated flexure piece.
- 10. The method as claimed in claim 9, wherein said fixing step is executed after said head IC chips are mounted but before said coupled flexure pieces are separated into individual pieces.
- 11. The method as claimed in claim 9, wherein said fixing step is executed after said coupled flexure pieces are separated into individual pieces.
- 12. The method as claimed in claim 1, wherein said forming step comprises a step of forming the plurality of flexure pieces coupled with each other from a flat sheet material.
- 13. The method as claimed in claim 1, wherein said forming step comprises a step of forming the plurality of flexure pieces coupled with each other from a rolled hoop material.
- 14. The method as claimed in claim 3, wherein said mounting step comprises a step of mounting sliders with magnetoresistive type read out magnetic head elements on the respective flexure pieces.
- 15. A method for manufacturing a magnetic head suspension assembly comprising the steps of:forming a plurality of flexure-load beam pieces coupled with each other and lying flat over their combined surfaces, each of said flexure-load beam pieces-being-provided with a conductive connection pattern; mounting head IC chips on respective ones of the substantially flat flexure-load beam pieces, said mounting being executed before said flexure-load beam pieces are bent; and separating said flexure-load beam pieces with the head IC chips into individual pieces.
- 16. The method as claimed in claim 15, wherein said method further comprises a step of checking electrical characteristics of said mounted head IC chips, said check being executed before said flexure-load beam pieces are bent.
- 17. The method as claimed in claim 15, wherein said method further comprises a step of mounting sliders with magnetic head elements on the separated flexure-load beam pieces.
- 18. The method as claimed in claim 15, wherein said head IC chip mounting step comprises a step of mounting the head IC chips on the respective flexure-load beam pieces by flip chip bonding process.
- 19. The method as claimed in claim 15, wherein said head IC chip mounting step comprises a step of mounting the head IC chips on the respective flexure-load beam pieces by ultrasonic bonding process.
- 20. The method as claimed in claim 17, wherein each of said flexure-load beam pieces has a tongue portion for fixing the slider, and wherein said method further comprises a step of bending the tongue portions of the respective flexure-load beam pieces so as to adjust static attitude of the sliders to be attached, said tongue portion bending step being executed before said head IC chips are mounted.
- 21. The method as claimed in claim 17, wherein each of said flexure-load beam pieces has a tongue portion for fixing the slider, and wherein said method further comprises a step of bending the tongue portions of the respective flexure-load beam pieces so as to adjust static attitude of the sliders to be attached, said tongue portion bending step being executed after said head IC chips are mounted but before said coupled flexure-load beam pieces are separated into individual pieces.
- 22. The method as claimed in claim 17, wherein each of said flexure-load beam pieces has a tongue portion for fixing the slider, and wherein said method further comprises a step of bending the tongue portions of the respective flexure-load beam pieces so as to adjust static attitude of the sliders to be attached, said tongue portion bending step being executed after said coupled flexure-load beam pieces are separated into individual pieces.
- 23. The method as claimed in claim 15, wherein said method further comprises a step of bending each of the flexure-load beam pieces.
- 24. The method as claimed in claim 23, wherein said bending step is executed after said head IC chips are mounted but before said coupled flexure-load beam pieces are separated into individual pieces.
- 25. The method as claimed in claim 23, wherein said bending step is executed after said coupled flexure-load beam pieces are separated into individual pieces.
- 26. The method as claimed in claim 15, wherein said forming step comprises a step of forming the plurality of flexure-load beam pieces coupled with each other from a flat sheet material.
- 27. The method as claimed in claim 15, wherein said forming step comprises a step of forming the plurality of flexure-load beam pieces coupled with each other from a rolled hoop material.
- 28. The method as claimed in claim 17, wherein said mounting step comprises a step of mounting sliders with magnetoresistive type read out magnetic head elements on the respective flexure-load beam pieces.
