The base sheet can exhibit excellent performance in respect of peeling resistance, soldering heat resistance, dimensional stability and solvent resistance as well as workability into a printed circuit board only when each of the layers (a), (b) and (c) has a specified thickness in a narrow range of 10-30 &mgr;m, 5-15 &mgr;m and 5-15 &mgr;m, respectively.Type: GrantFiled: July 2, 2001Date of Patent: September 16, 2003Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Masahiro Yuyama, Hitoshi Arai, Yoshitsugu Eguchi

Patent number: 6613438Abstract: The invention relates to a one-component epoxy resin adhesive which is elasticated with silicone rubber and whose open joint time is adaptable to whichever production process it is being used in by the concentration of UV initiator and/or the duration and/or intensity of UV activation and which is therefore particularly suitable for automatable manufacturing processes, since the workpieces after initial fixing require no additional mounts even during thermal aftercuring. This adhesive is preferentially suitable for the extensive adhesive bonding of permanent magnets, such as in the assembly of a permasyn motor, for example.Type: GrantFiled: July 26, 2001Date of Patent: September 2, 2003Assignee: Siemens AktiengesellschaftInventors: Peter Hein, Winfried Plundrich, Ralf Wilcke, Ernst Wipfelder

Publication number: 20030118835Abstract: An underfill material is presented that may be used between an electrical component and a substrate. The underfill material may be a cured epoxy resin composition comprising a liquid or semisolid epoxy resin and a polyfunctional anhydride polymer and/or oligomer curing agent. The use of anhydride polymers and/or oligomers decrease the volatilization of the composition, thereby reducing the porosity of the underfill material. By changing substituents of the anhydride polymer and/or oligomer, the underfill material may be designed to modify viscosity, decrease moisture adsorption, volatilization and modulus, improve mechanical properties, and enhance adhesion.Type: ApplicationFiled: December 21, 2001Publication date: June 26, 2003Inventors: Saikumar Jayaraman, Rahul Manepalli
