Part Clamping: Vacuum vs. MechanicalDownload the eBook!
Why is part clamping needed?
• A wire bond is made with ultrasonic vibration (often in combination with applied heat)
- If the part is not held stationary relative to the tool, the bond either cannot be made or is poor quality
- The substrate must be clamped on the tooling so that it does not shift relative to the part being placed, which could cause misalignment and bond failure
