Wire Bonding
Gold Stud Bumping
The gold ball bumping process creates conductive gold balls or stud bumps on the die bond pads. Gold stud bumping is a process used with die attach methods including flip chip bonding. The ball size depends on bonding wire size, the length of the tail (the wire used to make the ball) and the electronic flame off (EFO) power used to create the ball.
