Abstract: A pre-patterned circuit board device-attach transfer tape is described which allows a one step mounting of adhesive patterns on a circuit board in the desired configuration for later mounting of surface mounted devices (e.g., semiconductor dies) thereon. The tape product contains the adhesive pattern in a mirror image to that desired on the exposed surface of the circuit board. The product of the present invention is utilized by bringing the tape product into contact with the circuit board so that the adhesive on the carrier film bonds to the desired surface of the circuit board thereby bringing the adhesive patterns into the desired configuration desired on the circuit board. The use of pressure and, possibly, heat preferentially bonds the adhesive to the circuit board and allows for later stripping of the support film from the support film/adhesive/circuit board composite.

Abstract: A roll of composite tape composed of an adhesive tape and a strippable backing tape is paid out, and the adhesive tape and the strippable tape are separated. A circular hole of predetermined diameter is punched through the strippable tape, and the strippable tape and the adhesive tape are brought back together again such that a circular portion of the adhesive face of the adhesive tape remains exposed through the circular hole punched in the strippable tape.

Abstract: A cigarette carton structure having a releasable adhesive seal to permit reopening of a temporarily sealed carton without damage to the carton. The seal includes a release coating on one of two carton surfaces to be adhesively joined. One of the surfaces may be a top flap and the other surface may be a closure flap. An adhesive is placed on the release coating, and the two surfaces are joined. The release coating may be a weakly cohesive material such as a metallic ink printed on the carton surface so that when the surfaces are separated, the release coating separates without damaging the carton. Alternatively the release surface can be a layer of material that adheres poorly to the adhesive, so that the adhesive readily separates from the release layer. In either case the initial temporary bonding must be sufficiently strong to allow handling, packing and unpacking of the cartons without premature opening.
