  • LOW DIELECTRIC GLASS FIBER
    Publication number: 20110042129
    Abstract: A glass fiber having a low dielectric constant and low dielectric loss tangent consists essentially of by weight, as a glass composition, 52 to 60% of SiO2, 11 to 16% of Al2O3, 20 to 30% of B2O3, and 4 to 8% of CaO, and substantially no MgO, substantially no Li2O, substantially no Na2O, substantially no K2O, and substantially no Ti2O. The glass fiber also may contain up to 2% F2 by weight. The glass fiber is ideal for use as reinforcement for printed wiring boards, and has excellent dielectric properties at frequencies of about 18 GHz or higher.
    Type: Application
    Filed: October 26, 2007
    Publication date: February 24, 2011
    Applicant: AGY HOLDING CORP.
