Abstract

SMD technology in PWB assembly requires the use of dedicated robots (pick-and-place) which feed discrete components from reeled carrier tapes. A heat-sealed tape is used to hold the components in the tape pockets until the moment of application. If the tape adhesion is above or below specified strength, a machine stall oc- curs. These stoppages severely impact production through-put.

TAPE ADHESION PEEL STRENGTH TESTER

by George Louis Pappas

   SMD technology in PWB assembly requires the use of dedicated robots (pick-and-place) which feed discrete components from reeled carrier tapes. A heat-sealed tape is used to hold the components in the tape pockets until the moment of application. If the tape adhesion is above or below specified strength, a machine stall oc- curs. These stoppages severely impact production through-put.

   An analysis was made of the automated pick-and-place function and stoppages due to improperly sealed tape were found to cost well over ten percent of machine running time. Datawas collected on the peel strength of all suppliers' seal tapes and few were found to fall within the range of the industry's established standards. The equipment used to measure adhesive strength in this study was far too expensive and complex to be used in operations involving direct labor. A device was needed that was easy enough to operate that it could be used by both incoming inspection personnel and direct labor monitoring materials on production lines. The tester also had to be sufficiently inexpensive that small suppliers could afford to reproduce it at their own facility thus permitting correlation of tape testing throughout the industry.

The Tape Adhesion Peel Strength Tester offers a simply operated, compact and inexpensive means of testing seal tape adhesion on reeled discrete compon...
