Abstract
A carrier tape which includes a punched tape with a plurality of aperture cavities, and a backing tape having a thin flexible gel material between a pair of strips of parallel pressure sensitive adhesive material. The flexible gel material covers all of the aperture cavities of the punched tape, so that singulated die and other components with a single flat surface can be placed on the surface of the flexible gel layer to hold the die or other component precisely in place, even during handling or shipping. The gel layer has high resistance to shear forces (movements in X, Y and theta) yet minor resistance to peel forces (removal in the Z-axis). The die is retained within an aperture cavity and it is adhered to the thin flexible gel layer such that the small component is unable to move in the X, Y or theta directions. The gel layer holds the die in place securely while the carrier tape is moving during processing and prevents fallout or dislocation of the die during high speed automated processing.
