Abstract

An apparatus for determining an orientation of a die mounted on a tape includes an imaging device, a light source and a conveying mechanism. The die is at least partially translucent and includes at least one orientation feature indicative of the orientation of the die. In use, the conveying mechanism conveys the tape to position the die at an inspection position between the imaging device and the light source. The light source projects light to the imaging device and the imaging device captures an image. The projected light from the light source passing through the die is obstructed by the at least one orientation feature of the die to cause the captured image to include an image of the at least one orientation feature, whereby the orientation of the die may be determined.
