Abstract
An apparatus and a method for detecting a tension abnormality in a dicing tape, to quantitively determine whether or not tension of the dicing tape is appropriate and accurately detected. A tension abnormality detecting apparatusincludes an air micrometerthat measures, displacement of a dicing tape DT occurring when air is blown to a measurement point P to which a workpiece W is not affixed. A determination unitdetermines the tension of the dicing tape DT is appropriate when the tension of the dicing tape DT at the measurement point P belongs in a previously set proper range and determines that the tension of the dicing tape DT is abnormal when the tension of the dicing tape DT at the measurement point P does not belong in the proper range.
