Abstract:
PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive that realizes both of contradictory properties of enhanced pressure-sensitive adhesive force and ready peelability, suppresses scattering of electronic components on dicing and exhibits large effects for suppressing static electricity when an electronic component is picked up, a pressure-sensitive adhesive sheet obtained using the same and a manufacturing method of electronic components using the pressure-sensitive adhesive sheet. SOLUTION: The pressure-sensitive adhesive comprises an elastomer having a halogen-containing monomer unit and a heat-polymerizable compound. The pressure-sensitive adhesive sheet is obtained using the same. The manufacturing method of the electronic component comprises using the pressure-sensitive adhesive sheet. The pressure-sensitive adhesive and the pressure-sensitive adhesive sheet are suitably employed for a pressure-sensitive adhesive sheet for fixing electronic components that is pasted on the back surface of an electronic component aggregate when a plurality of electronic component aggregates formed on a plate-like substrate is divided into a separate electronic component by dicing.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a thick graphite sheet by laminating multiple graphite sheets while maintaining thermal conductivity and flexibility. SOLUTION: There is provided a thick laminated graphite sheet having good flexibility and small thermal resistance by painting a resin solution on a surface of a graphite sheet and bonding two or more graphite sheets.
Abstract:
PROBLEM TO BE SOLVED: To provide a solder paste in which the organic halide compound to be blended to improve the solder wettability is sufficiently decomposed under the reflow condition without generating any ionic halogen, the performance as the solder paste is kept, and further the solder wettability is kept in a excellent condition, and the reliability of the product is excellent for a long time even without any cleaning. SOLUTION: In the solder paste in which the organic halide compound is blended as the activator, the flux in which 0.005-2.0wt.% polymer containing at least one of polyethylene glycol, poly-N-vinyl acetamide and poly-acrylic acid having the complex forming ability to the metal is added to the total weight of the flux, is blended.
Abstract:
Vinyl chloride-grafted ethylene copolymer superior in adhesiveness both to metals, glasses or polar high molecular materials such as polyamides and to non-rigid vinyl chloride resins is provided in which backbone polymer is copolymer of ethylene, ester of monohydric alcohol of 1 - 8 carbon atoms with acrylic acid or methacrylic acid and maleic anhydride and pendant or grafting polymer is vinyl chloride polymer. This copolymer is produced by graft-polymerization of vinyl chloride onto the ethylene-acrylic or methacrylic ester-maleic anhydride copolymer.
