Problems solved by technology

[0006] In addition, since the general-purpose glass cloth has hollow fibers containing air bubbles, the plating solution, cleaning solution, etching solution, etc. used in the substrate forming process will seep into the air bubbles in the cloth, so that the plating layer cannot be adhered, resulting in damage. The above defects: the occurrence of poor conduction and the reduction of dielectric properties, etc.

Embodiment 1～2、 comparative example 1～7

[0131] (Preparation of quartz glass fiber)

[0132] Glass cloths having a thickness of 0.1 mm used in Examples 1 to 2 and Comparative Examples 1 to 7 were prepared using glasses shown in Table 1 below. Table 1 also describes the types and doses of α-rays, and the ion components of Na, Li, and K. In addition, the quartz glass cloths of Comparative Examples 6 and 7 were prepared by adding an ionic component when producing the quartz glass cloth of Example 1.

Abstract

The present invention is a quartz glass fiber-containing prepreg, which is characterized by including: (A) a quartz glass fiber; and (B) a curable resin composition, wherein at least one condition ofconditions: (1) a dose of alpha-ray contained in the quartz glass fiber is 0.005 c / cm<2>*hr or smaller, and, each of metal ion contents of Na<+>, Li<+> and K<+> is 1 ppm or lower; (2) the quartz glassfiber contains the number of foams of 10 foams / m<2> or smaller a unit area; and (3) the quartz glass fiber-containing prepreg has the common bending stiffness in the range of a thickness of 100 to 200 [mu]m measured by a method described in JIS R 3420:2013 of 500 N*m<2> or larger is satisfied. This provides a quartz glass fiber-containing prepreg that has particularly excellent dielectric characteristics, has excellent dielectric characteristics and the heat resistance, and / or has high handling property because of high bending stiffness characteristics.

Description

technical field [0001] The invention relates to a prepreg containing quartz glass fiber, a film containing quartz glass fiber and a substrate containing quartz glass fiber. Background technique [0002] With the development of digital technology, electronic equipment represented by personal computers and mobile phones has become thinner, lighter, smaller, and more functional. Therefore, for example, printed circuit boards, which are typical components, require high-density packaging and thinner and smaller sizes. In response to this situation, there is a strong demand for improved properties of glass fiber-containing prepregs, glass fiber-containing substrates, and films. [0003] In addition, with the advancement of high-speed and high-frequency computers, mobile devices, and communication infrastructure, etc., there is a demand for low-dielectric substrates and films that have excellent transmission loss, that is, low transmission loss, which is a characteristic required f...
