The present invention features a method and apparatus wherein a component
in a component placement machine is rejected during the placement cycle
and subsequently retained in a component rejection station. A component
is imaged and the image processed using an automated vision system. The
image processing determines whether the component is placeable based upon
a comparison of the component image to preprogrammed mechanical
parameters for the component. A non-placeable component is rejected into
a reject station with means to retain the component. Because a component
can not escape the reject station, there is no degradation of the
placement machine performance.
