Abstract

Disclosed is a wire spool system for a wire bonding apparatus, comprising: a wire reel arranged to receive a wire; a wire guide for feeding a free end of the wire to a bond head of the wire bonding apparatus; and a tensioning mechanism for tensioning the wire to define a wire path between the wire reel and the wire guide. The wire spool system comprises an imaging module comprising a camera having an image sensor. The imaging module also comprises an image processing unit. The camera is positioned to image, by said image sensor, at least a portion of the wire path to generate image data. The image processing unit is configured to process the image data to determine a geometry and/or a change in geometry of the at least a portion of the wire path.
