Abstract
Approaches for helping to decrease the amount of inactive gas necessary for reflow to interconnect connection terminals of a head slider and a suspension. Inactive gas is blown from a nozzle of a reflow apparatus toward interconnection joints of a head slider and a suspension. The head slider is bonded onto a gimbal tongue. The nozzle comprises a duct through which the inactive gas passes and a porous member fitted in an ejection outlet of the tube. Placing the porous member close to the head slider achieves effective reduction of oxygen concentration around solder balls.
