Patent ID: 7137188

Claim:
A method of constructing an integrated lead suspension, comprising: providing a lead wiring pad on a flexure section of the suspension and a bonding pad on a slider of a head gimbal section of the suspension; placing a solder ball between the lead wiring pad and the bonding pad, such that the solder ball is melted to solder the lead wiring pad and the bonding pad together; wherein the method of constructing further comprises the steps of: first forming the lead wiring pad having a flat surface; thereafter providing a recessed section into which the solder ball is dropped from the flat surface of the lead wiring pad, using gravitational force, in the vicinity of a center line of the flat surface of the lead wiring pad; and wherein the recessed section is formed by a method selected from the group consisting of bending and die pressing the suspension to form a pair of upward-turned sections that are turned upward from the recessed section, such that one upward-turned section is located on each side of the centerline.
