Gold Stud Bumping

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.

Ball Bumping at our Facility

At the Advanced Packaging Facility we can create gold bumps on the die bond pads, with the bump's diameter down to 60μm(approx.), pad pitch at 100μm.
