Publication number: 20010014705Abstract: Epoxy laminates incorporate up to 20 wt. % talc particles, particularly pure Montana platy talc particles having a maximum particle size of about 40 &mgr;m providing improved drilling performance, reduced dust formation, and improved Z-direction CTE, particularly when the epoxy resin has a Tg of about 150° C. or higher. The talc is selected from those which do not significantly reduce the electrical strength of the laminate relative to those which contain no talc particles. Characteristically, the talcs will have less than 5 wt. % impurities and less than 0.01 wt. % (100 wt.ppm) water extractable anions.Type: ApplicationFiled: December 13, 2000Publication date: August 16, 2001Applicant: Isola Laminate Systems Corp.Inventors: Aroon V. Tungare, Scott H. Richgels, Jeffrey R. Kamala, Peggy M. Conn

Patent number: 6255039Abstract: High density built-up multilayer printed circuit boards are produced by constructing microvias with photoimageable dielectric materials. A photosensitive dielectric composition on a conductive foil is laminated to conductive lines on a core. After imaging the foil and imaging and curing the photosensitive dielectric composition, vias are formed to the conductive lines. Thereafter the conductive lines are connected through the vias to the conductive foil, and then the conductive foil is patterned.Type: GrantFiled: April 3, 1998Date of Patent: July 3, 2001Assignee: Isola Laminate Systems Corp.Inventors: Chengzeng Xu, James T. Yardley, David Haas, Michael Vallance, Jeffrey T. Gotro, Michael A. Petti

Patent number: 6242078Abstract: The present invention is a method and apparatus for providing an electrical substrate. The electrical substrate comprises a dielectric layer having a surface roughness of no greater than 6.0 microns. A first conductive layer is attached to the dielectric layer. In one embodiment, the dielectric layer comprises a laminate that comprises a cloth having a uniform weave and a resin that is consistently impregnated within the uniform weave. A removable layer may be attached to the laminate and removed prior to metallizing of the first conductive layer. Various embodiments are described.Type: GrantFiled: July 28, 1998Date of Patent: June 5, 2001Assignee: Isola Laminate Systems Corp.Inventors: Richard J. Pommer, Jeffrey T. Gotro, Nancy M. W. Androff, Marc D. Hein, Corey J. Zarecki
