The jumper conductor includes a branch-side metal portion, a pad-side metal portion, and a bridge portion. The bridge portion is formed between the branch-side metal portion and the pad-side metal portion. The branch-side metal portion electrically conducts to connecting terminals of the first branch conductors via branch-side connecting members. The pad-side metal portion electrically conducts to an electrode pad via a pad-side connecting member. The bridge portion includes a crossover portion which crosses over a third conductor member.

Abstract: A cutting jig is used in a method of reworking a head suspension which removes a slider from the head suspension by pressing a blade from a first side toward a second side in a longitudinal direction of the slider to solder ball bonding, stopping the second side of the slider in the longitudinal direction with a holding mechanism, and forcing the blade to bite and cut the solder ball bonding to remove the slider from the flexure. The cutting jig includes a cutting mechanism configured to press a blade to the bonding material from the first side toward the second side in the longitudinal direction of the slider, and a holding mechanism stopping the second side of the slider in the longitudinal direction when the blade is pressed to the bonding material.
