The Cu bump shear machine used was a Nordson Dage 4000. The shear height is 15µm from the bottom of the Cu bump. The shear speed is 300µm/s. The tip has a flat end. The typical images after bump shear are shown in Figure 5.
WebSep 1, 2014 · The bump is mechanically weakened which results in a changed breakage mode while an electrical contact is present. The standard shear test by JEDEC is not able to detect such an application relevant failure mode.
