Software tools are available for a very high-resolution camera module that provides measurements of balls and wedges. Reportedly measures 25 µm gold thin-wire wedge sizes with a standard deviation of 1 µm. Inspects qualitative characteristics of wire bonds; balls and wedges statistical evaluation and trend analysis of critical geometric dimensions can be performed. For gold wire bonds with diameters less than 25 µm, the VHR module's illumination enhances geometric features. Resolution of approximately 3 µm per pixel produces standard deviations in wedge widths of 1 µm.
