CONDUCTIVE SHEET AND EMBOSSED CARRIER TAPE
An object of the present invention is to provide a conductive sheet and an embossed carrier tape that can reduce detachment of carbon black and prevents deterioration of buckling strength. A conductive sheet for an embossed carrier tape for mounting an electronic component, in which the conductive sheet has a configuration in which a surface layer having conductivity is laminated on at least one surface of a core layer; the core layer and the surface layer each contain a common material constituted of only a combination of three types of polystyrene-based resins of styrene-butadiene copolymer resin, general purpose polystyrene resin, and high impact polystyrene resin; a common material constituting the core layer and a common material constituting the surface layer have the same compounding ratio; and the surface layer is formed by kneading carbon black in the common material.

CARRIER FOR REVERSIBLY IMMOBILIZING ONE OR MORE OBJECTS
A carrier for reversibly immobilizing one or more objects is disclosed. The carrier comprises a frame having a major axis, a top surface, a bottom surface, and one or more openings through the frame along the major axis. The carrier also comprises a film comprising a thermoplastic elastomer material and having a top surface and a bottom surface. The film is attached to the frame based on thermal bonding of the top surface of the film to the bottom surface of the frame, is under tension along the major axis, and is free to flex at the openings. The top surface of the film comprises one or more exposed top surface portions that are accessible through the openings. The exposed top surface portions exhibit a holding force on stainless steel as per ASTM D1000 that is greater than that of the bottom surface of the film.
