A method and apparatus for facilitating validation of component feeder
exchanges in pick and place machines are provided. A pre-exchange image
of a component from a feeder is acquired and compared with an image a
component from the exchanged feeder placed after the feeder exchange. A
comparison of the pre-exchange image with the post-exchange image
facilitates simple and quick feeder exchange validation. Aspects of the
present invention are practicable with different types of pick and place
machines, and are able to advantageously use sensors and/or technician
supplied information to generate automatic indications of feeder exchange
validity.
