Wire Bonding Theory and DOE (Design Of Experiments)

(1 DAY)


This course is intended for those interested in understanding the basic theory of wirebonding from a materials and process perspective.  The instructor will explain the underlying material science behind forming a wirebond interconnect and walk through several “real world” DOEs to show how wirebond schedule settings can be optimized by running carefully controlled experiments. These important skills will enable engineers to return to their workplace and improve wirebond yield and reliability in the customer applications.


Course Outline


The Wire Bond Process:
    Thermosonic gold ball bonding
    Wedge and ribbon bonding
