Abstract

Removing welded outer lead bonds of TAB tape leads to contacts on a substrate. The method includes separating the electrical leads adjacent the weld bonds leaving a remnant, engaging the remnant with a shear tool, and moving the tool and bond relative to each other shearing the remnant. In some cases the tool is ultrasonically vibrated in a direction transversely to the relative movement of the tool and bond.
