Understanding the Wire Bonding Process

PDC Instructor: Lee Levine, Process Solutions Consulting

Tuesday, February 9 - preceding the Workshop/Sessions
Additional registration fee from Workshop Registration

Course Description: Wire Bonding is a welding process that is the dominant chip interconnection method. More than 15 trillion wires are bonded annually. In the past gold wire was predominant but this year copper and palladium coated copper wire will capture more than 51% of the total market. Copper provides benefits in cost, improved conductivity, stiffness and reliability. However, it is significantly harder than gold and achieving a robust, reliable process is a challenge. Wire bonding high-volume lead-frame often experiences defect rates below 10ppm, this presents a significant barrier to entry for any process competitor but copper is meeting the challenge.

The flexibility, reliability and yield of wire bonding make it a process worthy of careful study. Today’s wire bonding equipment is capable of producing 24 wires/second (48 welds) with bond placement accuracy of ±2.0µm. During the descent of the tool the bond head has an acceleration of >300g. Achieving highly repeatable bonds with the stated bond placement accuracy and yet accelerating at 300g requires exceptional engineering design. As a result the wire bonder has evolved into one of the worlds most advanced machines. It requires high speed pattern recognition, ultra-light (for speed and acceleration), stiff (for accuracy and repeatability) sub-assemblies (imagine trying to achieve the same speed and accuracy with a graphite fishing rod), and state-of-the-art control systems.

PDC Coffee Break: 10:00 am - 10:15 am
