Abstract: A carrier tape for electronic or electrical devices which contains a support film containing pockets and, within each of the pockets, a fastening layer having a fixed portion which is attached to the floor of the pocket and a release portion which is composed of a flexible polymeric film, preferably a soft elastomer film, and which can be deformed away from the floor without detaching the fixed portion from the floor. The devices are placed on the release portions of the fastening member.

Abstract: A carrier tape for electronic or electrical devices which contains a pocketless support film, a fastening layer on the support film, and a deformable cover film separably attached to the fastening layer. The devices are sandwiched between the fastening layer and the cover film, which deforms to provide an enclosure for the devices.

Abstract: Method and apparatus for handling semiconductor chips and the like are disclosed which include the use of a flat flexible film which is attached to the face of a base member. The face of the base member is formed with recesses covered by the flat flexible film. Chips are loaded onto the flat flexible film in good surface contact therewith whereby they are securely held in position by interfacial, adhesive, or other forces between the chips and film. To facilitate removal of chips from the film, the recesses are connected to a vaccuum source, drawing portions of the flexible film into said recesses and providing the film with a texturized, or undulating, surface. The area of contact between the chips and film is thereby reduced which, in turn, results in a reduction in the force by which the chips are attached to the film, thereby enabling removal of the chips by conventional techniques.

Abstract: Method for handling semiconductor chips and the like objects are disclosed which include the use of a flat flexible film that is supported on a flat porous texturized fabric sheet such as a woven or knit fabric having spaced fiber crossovers. Objects, are supported on the flat flexible film in intimate surface contact therewith for securely holding the same in position by interfacial forces therebetween. Adhesive may be included for increasing the interfacial force. To facilitate removal of objects from the film, the fabric is connected to a vacuum source for drawing portions of the flexible film over and between crossovers in the fabric whereby portions of the flexible sheet are withdrawn from the objects. The contact area and interfacial forces between the flexible sheet and objects is thereby reduced to enable removal of the objects from the sheet using conventional object handling techniques.
