What is Ribbon Bonding?
Understanding Ribbon Bonding Process
Ribbon bonding comprises utilizing a flat metallic ribbon as a connecting medium between semiconductor devices and substrates. Unlike traditional wire bonds which employ around wires, ribbon bonds are characteristically thicker and wider. This design enables for more suitable current-wearing advantage and more suitable thermal dissipation.
The ribbon bonding task consists of countless extreme steps:
Preparation: The surfaces to be bonded are wiped clean to eliminate any contaminants which can have an effect on bond nice. Placement: The ribbon is located at the precise pad or surface at the chip or substrate. Bonding: Using either ultrasonic or thermosonic systems, heat and tension are carried out to create a robust bond among the ribbon and the floor. Inspection: Post-bonding inspection ensures that the bonds meet first-rate necessities with out defects.Types of Ribbon Bonding Techniques
Different ways can also be employed in the course of the ribbon bonding process:
- Ultrasonic Ribbon Bonding: Utilizes excessive-frequency sound waves to generate heat on the bond interface. Thermosonic Ribbon Bonding: Combines ultrasonic energy with thermal electricity for more advantageous bond potential.
Both processes show off distinguished merits relying on drapery homes and application requisites.
