LOW DIELECTRIC CONSTANT LOW DIELECTRIC DISSIPATION FACTOR GLASS FIBER

摘要

PROBLEM TO BE SOLVED: To provide a glass fiber for a printed wiring board which is free from the occurrence of work defects in the work of component holes even when UV-YAG third higher harmonic laser of 355 nm wavelength is used. SOLUTION: The low dielectric constant low dielectric dissipation factor glass fiber is composed of glass having a dielectric constant of≤5.0 at 1 MHz and≤10% light transmittance at 0.5 mm thickness and 355 nm wavelength.
