Title:
ロール状長尺ガラスクロス、プリプレグ、及びプリント配線板
Document Type and Number:
Japanese Patent JP7317519
Kind Code:
B2
Abstract:
To provide a roll-shaped long glass in which the heat resistance is high when it is combined with the low dielectric resin to use, the distortion of the knitted structure, such as wrinkle and the like, is suppressed, and the variation of the size change is less when it is arranged to be the printed wiring board, and a prepreg as used with the glass cloth and a printed wiring board.SOLUTION: The roll-shaped long glass cloth is constituted of the glass fiber comprising the plurality of glass filaments, as the warp and the weft, and is that the glass cloth as surface treated with the surface treating agent is wound to the core tube, and the thickness of the glass cloth is 8 micrometers or more and 100 micrometers or less, the ratio between the thickness and the gap width of the warp (thickness/gap of warp) is 0.18 or more and 2.0 or less, the roll density (kg/m) of the roll-shaped long glass cloth is 1.02 folds or more and 1.25 folds or less of the sheet density (kg/m) of the glass cloth, and the surface treating agent is the silane coupling agent having unsaturated double bond.SELECTED DRAWING: Figure 1
