At present, Nittobo is one of the few companies worldwide that has the coherent facilities from fiber manufacture, to glass cloth processing and the research of composite materials, and has a presence in Japan as the top manufacturer, ultra-thin glass fabric yarn
Nowadays, for promoting to higher speed and frequency in the area of computer, mobile phone, and telecommunication infrastructure etc., low dielectric constant and dissipation factor base materials for PWB will be required for next generation materials. Nittobo have proprietary developed low dielectric constant and dissipation fiber glass fabric using NE-glass yarn in replacement using E-glass yarn.
E-Glass 6.6 0.0012
NE-Glass 4.6 0.0007
For applying T-glass yarn which has low-thermal expansion and high modulus elongation property, excellent dimensional stability and higher stiffness will be able to materialize.
Heat expansion coefficient
（×10-6/°C） Modulus of elongation （GPa）
E-Glass 5.5 72.8
T-Glass 2.8 84.3
To respond HDI and high-tech PWB trend, thinner glass fabrics are required. Nittobo’s ultra thin fabric have not only thin cloth but also advantage for lazar or mechanical micro-via property, dimensional stability, and smoother surface.
