Cavity Shear

Nordson DAGE bondtesters provide cavity shear testing (up to 5kg) as an alternative method for applying a load to a solder ball or ball bond. It is particularly useful for applications where the ball bond is surrounded by a thick layer of passivation which prevents the normal positioning of the loadtool for landing, touchdown and shear height control.

The patented Nordson DAGE cavity shear test methodology overcomes passivation interference and removes the maximum amount of material which is difficult to achieve using a traditional chisel style loadtool.  In addition due to the uniform way in which the load is applied, deformation of the ball bond is minimized during the test.
