The present invention provides a production method of an anisotropic conductive film, which method includes the steps of (a) winding an insulated wire around a core member to form one roll of a winding layer, this insulated wire including a metal conductor wire and a coating layer made from an insulating resin, this coating layer being formed on the wire, placing an insulating resin film on the obtained winding layer, and repeating the winding and the placing to give a laminate alternately having the winding layer having a single row of insulated wires and an insulating resin layer made from the insulating resin film, (b) partially or entirely melting at least one of the coating layer and the insulating resin layer to integrate the winding layer and the insulating resin layer, and (c) slicing the laminate along a plane forming an angle with the insulated wire in a desired film thickness.
摘要:
A sealing label for sealing semiconductor element comprises a metal foil substrate or a heat-resisting organic film substrate having formed thereon a sealing material component layer for sealing a semiconductor element, wherein the sealing material component layer is convexly formed such that the layer has a thick flat portion at the central portion of the substrate as compared with the peripheral portion of the substrate. The use of the sealing label in molding a semiconductor device can provide a semiconductor device having a high quality without substantially having voids in the sealing resin.

There is disclosed a heat-sensitive transfer recording medium comprising a support and, provided thereon, a colorant-containing layer for heat-sensitive transfer, wherein said colorant-containing layer contains a silicone wax as a heat-fusible material which is solid or semi-solid at ambient temperature or room temperature.The recording medium according to the present invention is capable of printing at low energy and with high transfer sensitivity.
摘要:
There is disclosed a thermal transfer recording medium which comprises a support, a coloring agent layer containing a heat fusible substance formed on one surface of said support and a backing layer on the other surface of said support, wherein said backing layer contains a resin selected from urethane resins or vinyl chloride resins and a higher fatty acid which is solid or meta-solid at room temperature.The thermal transfer recording medium of this invention can suppress effectively generation of the sticking phenomenon, and has no deleterious effect on the thermal head without either contamination or abrasion of the thermal head.
摘要:
A photosensitive silver halide emulsion comprising photosensitive silver halide grains which essentially consists of monodisperse globular-shaped grains. The grains may be prepared by adding a silver halide solvent to a silver halide emulsion containing monodisperse silver halide grains of regular crystal habit at a time between the complete formation of the monodisperse silver halide grains of regular crystal habit and before commencement of chemical sensitization.
