VIRTUAL: Copper and Gold Wire Bonding (3/16/2021 – 3/18/2021)
Instructor: Lee Levine
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 the dominant material in use, but in 2015 copper and palladium coated copper wire captured 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 more challenging.
With the high productivity and growth rate of wire bonding, it is one of the most reliable manufacturing processes. Achieving high yields requires rigorous attention to details and excellent statistical process control. Wire bonding high-volume lead-frames often generates defect rates below 10ppm, this presents a significant barrier to entry for any process competitor, but copper is meeting the challenge in high-volume manufacturing.

This course is intended for wire bond process engineers, technicians, quality control engineers and managers.
