CN201220995Y - Electronic grade glass fibre flat fabric - Google Patents

Abstract

The utility model discloses an electronic-grade glass fiber flat cloth which is woven by warp yarns and weft yarns. The electronic-grade glass fiber flat cloth is characterized in that the width of each warp yarn is 350 to 400 micrometers, each weft yarn is formed by 200 pieces of single fibers, and the diameter of each single fiber is 5 um. The electronic-grade glass fiber flat cloth has the advantages that the yarn bunch is loose, the structure is even, and compared with the common cloth, the wettability of the resin to the flat cloth and the laminating workability of the copper-clad plate and the laminated board are all enhanced, and the performance of the produced basal plate is greatly enhanced; the yarn bunch is widened, the gap between the yarn bunches becomes small and is even zero, the thickness is thinned, and the evenness of the electronic-grade glass fiber flat cloth is enhanced, and the immersion speed for the resin is increased by one time; and the electronic-grade glass fiber flat cloth is suitable for the copper-clad plate with high precision, evenness and performance.

Description

The flat cloth of electronic-grade glass

Technical field

The utility model relates to the flat cloth of a kind of electronic-grade glass.

Background technology

Along with electronic product develops to light, thin, short and small direction, substrate also is required to develop to the direction of densification, frivolous multiple stratification and reliability, and so also the performance to electronics glass cloth has proposed requirements at the higher level: slimming, homogenising, resin wettability faster.Employed in the market electronics glass cloth (especially 1080 models), not carrying out flattening handles, substrate with such cloth production, various aspects of performance is not the most desirable, also more and more can not adapt to copper-clad plate manufacturer's requirement, especially to uniformity and the very high product of appearance requirement.

The utility model content

The utility model provides a kind of electronic-grade glass flat cloth according to deficiency of the prior art.

For achieving the above object, the utility model is achieved through the following technical solutions:

The flat cloth of a kind of electronic-grade glass, form by warp thread and weft yarn braiding, it is characterized in that, every bundle warp width 350-400 micron, every bundle warp thread is made up of 200 monofilament, and every filament diameter is 5um, every bundle weft width 350-400 micron, every bundle weft yarn is made up of 200 monofilament, and every filament diameter is 5um.

Wherein, 370 microns of preferred every bundle warp widths, 370 microns of every bundle weft width.

The flat cloth of electronic-grade glass in the utility model, make the yarn bundle become loose, structure becomes evenly, compares with using common cloth, resin all is improved to the lamination process of wettability, copper-clad plate and the laminated board of flat cloth, and the substrate of making has very big lifting on performance.Yarn Shu Biankuan, yarn interfascicular space diminishes almost and to disappear, the thickness attenuation, the uniformity of the flat cloth of electronics glass improves, and the infiltration speed of resin is doubled.Be applicable to high accuracy, high even, high performance copper clad laminate.

Description of drawings

Fig. 1 is the electronics glass cloth section structure schematic diagram in the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

As shown in Figure 1, the flat cloth of a kind of electronic-grade glass, form by warp thread 1 and weft yarn 2 braidings, 370 microns of every bundle warp widths, every bundle warp thread is made up of 200 monofilament, and every filament diameter is 5um, 370 microns of every bundle weft width, every bundle weft yarn is made up of 200 monofilament, and every filament diameter is 5um.

The foregoing description only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substantial equivalence means that it may occur to persons skilled in the art that are all in the utility model claim scope.

Claims (2)
