ABSTRACT:
A method for making a flexible carrier tape for storage and delivery of electronic components by an advancement mechanism is disclosed. The tape includes a strip portion having a top surface, a bottom surface opposite the top surface, and a device for engagingly receiving the advancement mechanism; and a plurality of aligned pockets for carrying the electronic components. The pockets are spaced along the strip portion and opening through the top surface. The device for engagingly receiving the advancement mechanism includes a plurality of hollow protuberances that are spaced equally along the strip portion, open through the strip portion, and extend outwardly from the strip portion. The protuberances are adapted to receive the advancement mechanism within the hollow portion. The method includes simultaneously thermoforming the pockets and the protuberances to provide excellent registration therebetween. Another method includes cutting the protuberances to form through holes for engagingly receiving the advancement mechanism.
