Component Tape Feeder Shear

      Described herein is a method to circumvent seal-tape breakage
while feeding taped SMT components in an automatic component
placement process.

      The component tape consists of a carrier tape, embossed and
perforated to accommodate the component and sprocket drive, and a
seal tape that is thermally bonded to the carrier tape. When the bond
strength exceeds the seal-tape strength, the tape tears, inhibiting
part presentation to the placement tool pick-up head.  When this
repeatedly occurs, manufacturing is severely impacted.

      The device utilized to circumvent this failure is a shear blade
mounted in the feeder mechanism approximately 0.01 inches behind the
seal-tape/carrier tape separation point. When the tear failure occurs
or is imminent, the blade completes the tape separation, thereby
eliminating breakage and manufacturing process interruption.
