Title:
COMPOSITE WOVEN FABRIC AND PRINTED WIRING BOARD
Document Type and Number:
WIPO Patent Application WO/2008/059741
Kind Code:
A1
Abstract:
Disclosed is a printed wiring board which attains aims of printed wiring boards
required for realizing high-speed, high-frequency semiconductor devices,
namely a printed wiring board having low dielectric constant, low dielectric
loss tangent and low linear expansion coefficient. Also disclosed is a composite
woven fabric suitably used as a base for such a printed wiring board. Specifically
disclosed is a composite woven fabric containing a quartz glass fiber and a polyolefin
fiber, wherein the ratio of the quartz glass fiber in the composite woven fabric
is set at not less than 10% by volume but not more than 90% by volume. It is preferable
that the quartz glass fiber has a filament diameter of not less than 3 μm
but not more than 16 μm, and the composite woven fabric has a thickness of
not more than 200 μm.
