DEVICE AND METHOD OF CHECKING CHIP MOUNTING DEVICE CASSETTE

摘要

PURPOSE:To provide a method and a device of checking the deviation of a cassette in suction point due to deformation or abrasion, where a master tape corespondent to a component enveloping tape is mounted in a chip mounting device cassette in place of a component enveloping tape. CONSTITUTION:A master tape 1 where component position detecting holes 3 are provided corresponding to the component position of a component enveloping tape, an optical sensor 7 provided at a component pickup station, and a comparison section 9 which checks a difference between the image-processed data of the component position detecting holes 3 and hole position data which serve as reference data are provided.
