Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
The K&S 4524 D is a gold ball bonder. K&S is the maker of the 4524 D. The 4524 D is a machine used for gold ball bonding.[1]
How it works
General reference — not yet source-verifiedA gold ball bonder forms a free-air ball at the end of a gold wire by melting the wire tip. The ball is placed on a heated bond pad under pressure and ultrasonic vibration. The bond is thermosonic because it combines heat, pressure, and ultrasonic energy.
The capillary tool guides the gold wire and shapes the ball onto the bond pad. The wire is then routed in a loop to the package lead, where the bond is completed and the wire is separated. An electronic flame-off device melts the wire tip to form the next free-air ball.
Where it fits in the process flow
General reference — not yet source-verifiedWire bonding is carried out in the packaging stage of semiconductor manufacturing. A gold ball bonder connects die bond pads to leadframes or substrates after wafer fabrication and dicing. The bonded assembly then proceeds to encapsulation and further package finishing steps.
Applications
General reference — not yet source-verifiedGold ball bonding is used in the assembly of integrated circuits, discrete semiconductors, and other microelectronic components. The process is suited to packages that require fine-pitch connections and high reliability.
