  • COMPONENT CARRIER TAPE WITH UV RADIATION CURABLE ADHESIVE
    Publication number: 20170162418
    Abstract: A carrier tape for transporting a plurality of components includes a flexible substrate extending along a longitudinal axis of the carrier tape, a plurality of pockets formed in the substrate and spaced apart along the longitudinal axis of the carrier tape, and an adhesive layer. Each pocket includes a bottom wall and a side wall extending from the bottom wall to a top surface of the flexible substrate. The adhesive layer is disposed on the bottom wall of each pocket in the plurality of pockets, such that when a component is placed in a pocket in the plurality of pockets, the adhesive layer in the pocket permanently bonds to the component, and such that when the adhesive is exposed to UV radiation the adhesive bond strength is sufficiently reduced so that the component can be removed from the pocket.
