Passivation shear

The passivation layer shear test methodology is applicable when the passivation layer is too thick for a cavity shear test to be effective and overcomes passivation layer interference.

The Nordson DAGE bondtester removes the passivation layer using a software controlled loadtool technique allowing the shear tool to engage the ball bond and apply the maximum load. A software routine combined with a specialized design loadtool cuts away the passivation and then allows for intelligent loadtool landing, stepback and shear.
