Abstract
A machine for separating a sheet of brittle material, for example a semiconductor wafer, into a plurality of pellets is disclosed. The pellets are defined by a plurality of intersecting scribed lines on the sheet. The machine includes a member for applying a shear force to an edge of the sheet whereby the maximum bending moment is applied at a preselected scribe line. The machine is particularly applicable for use with those semiconductor wafers which have a solder coating on both sides.
