摘要:
Embodiments of the invention relate to making reconnection when a soldered connection fails in a head/slider used in a magnetic disk drive. In one embodiment, a solder mass deposited on a slider pad of a head/slider is separated from a lead pad and a solder ball connection is yet to be made between the slider pad and the lead pad. A shaping tip is heated to a temperature near a melting point of a solder. The shaping tip is moved in parallel with a surface of the slider pad toward the side of the lead pad to soften the solder mass. The solder mass is thereafter irradiated with a laser beam so as to form a solder fillet, thereby making a soldered connection between the lead pad and the slider pad.

摘要:
An integrated lead suspension includes a solder ball that is placed between a lead wiring pad provided on a flexure of the suspension, and a bonding pad provided on a slider of a head gimbal section. The lead wiring pad and bonding pad are soldered by melting the solder ball. As a result, there is provided a recessed section into which a solder ball is placed by way of surface raised sections, using gravitational force, in the vicinity of the center line of the surface of the lead wiring pad. In this way the position of the solder ball is not displaced from the center line when a bonding pad and lead wiring pad are connected by means of a solder ball.
