Patent number: 7213739Abstract: The invention is directed to a fluxing curative for curing an underfill that comprises an epoxy resin and for fluxing a solder during a solder assembly of an electronic component to an electronic device substrate and a method for producing the fluxing curative. Specifically, the fluxing curative comprises a salt that is a reaction product of an imidazole component and a carboxylic acid component having at least 10 carbon atoms per molecule. Additionally, the invention is directed to an underfill solution comprising the fluxing curative and a method of attaching an integrated circuit device using the underfill solution.Type: GrantFiled: April 2, 2004Date of Patent: May 8, 2007Assignee: Fry's Metals, Inc.Inventors: Mark Wilson, James M. Hurley

Patent number: 7202304Abstract: 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: GrantFiled: March 8, 2006Date of Patent: April 10, 2007Assignee: Intel CorporationInventors: Saikumar Jayaraman, Rahul Manepalli
