What is Ribbon Bonding?
Understanding Ribbon Bonding Process
Ribbon bonding comprises through a flat metal ribbon as a connecting medium between semiconductor contraptions and substrates. Unlike common twine bonds which hire spherical wires, ribbon bonds are routinely thicker and wider. This layout permits for more suitable latest-wearing competencies and increased thermal dissipation.
The ribbon bonding job entails a couple of very important steps:
Preparation: The surfaces to be bonded are cleaned to do away with any contaminants which could impression bond pleasant. Placement: The ribbon is positioned on the detailed pad or surface on the chip or substrate. Bonding: Using either ultrasonic or thermosonic techniques, heat and tension are utilized to create a sturdy bond between the ribbon and the surface. Inspection: Post-bonding inspection ensures that the bonds meet high quality necessities without defects.Types of Ribbon Bonding Techniques
Different recommendations will probably be employed all over the ribbon bonding job:
- Ultrasonic Ribbon Bonding: Utilizes excessive-frequency sound waves to generate warmth at the bond interface. Thermosonic Ribbon Bonding: Combines ultrasonic strength with thermal vigor for enhanced bond potential.
Both tools exhibit pleasing advantages relying on fabric properties and application standards.
The Role of Ribbon Bonding in Power Modules
