ABSTRACT:
The invention is a method of determining whether a pick up apparatus has picked up a component in a normal manner. The method includes picking up a component with the apparatus, detecting at least one dimension of a projected image with of the component with an optical detector and determining whether the component has been picked up normally by determining whether the dimension of said projected image, less a correction factor based on the diffraction of light, is within a tolerance range.
