Abstract
The utility model discloses a large size stabilized fiberglass cloth, which is woven by warp and weft. The fiberglass cloth is characterized in that a plain weave structure is interleaved by the warp and the weft, each bundle of warp is composed of 800 to 850 monofilaments, the diameter of each monofilament is 6 to 6.5 micron, each bundle of weft is composed of 800 to 850 monofilaments, the diameter of each monofilament is 6 to 6.5 micron. The utility model makes the distribution of glass fiber uniform through changing the distribution form of yarn bundle and the plain weave structure interleaved by the warp and the weft, the permeability of epoxy resin can be increased, thereby each direction distribution of material in the whole plate is improved, the dimensional stability of the base plate and the quality reliability of micro holes are increased.
Description
Technical field
The utility model relates to a kind of electronic-grade glass fiber cloth, is specially a kind of electronic-grade glass fiber cloth that is applicable to high dimensional stability copper-clad plate.
Background technology
In the multilayer printed circuit board production technology, need earlier internal layer to be carried out, be bonded to a plate with prepreg hot repressing then, become multilayer printed circuit board behind boring, hole metallization, the system outer graphics.After often occurring internal layer in the actual production and having made, outer and internal layer hole position misalignment, the high meticulous printed circuit board little to the aperture, that conductor width is little causes can't connect and form waste product easily.Three kinds of raw material of printed circuit board: epoxy resin, electronics glass cloth and Copper Foil, thermal expansion character between the material differs greatly, therefore be difficult to accomplish do not have change in size fully, but the variation that as far as possible reduces substrate size of starting with from every side is still a very big problem.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of high size to stabilize glass fabric, by changing the distribution form of yarn bundle, the plain weave structure that longitude and latitude interweaves, make being evenly distributed of glass fibre, the impregnability of epoxy resin is improved, thus improved material in the whole sheet material each to distribution, improved the DIMENSIONAL STABILITY and the micro through hole reliability of substrate.
The utility model is achieved through the following technical solutions, high size of the present utility model is stabilized glass fabric, form by warp thread and weft yarn braiding, it is characterized in that, longitude and latitude is woven into plain weave structure, and every bundle warp thread is made up of 800-850 root monofilament, every filament diameter 6-6.5 micron, every bundle weft yarn is made up of 800-850 root monofilament, every filament diameter 6-6.5 micron.
Wherein, preferred described every bundle warp thread is made up of 800 monofilament, 6 microns of every filament diameters.
Wherein, preferred described every bundle weft yarn is made up of 800 monofilament, 6 microns of every filament diameters.
The utility model all obtains to improve in order to the every rerum natura of tellite (heat resistance, anti-ion transport, insulating reliability etc.) of producing through this structural change, and especially dimensional stability can improve more than 10%.
Description of drawings
Fig. 1 is a section structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment has provided detailed embodiment being to implement under the prerequisite with technical solutions of the utility model, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, a kind of high size is stabilized glass fabric, is formed by warp thread 1 and weft yarn 2 braidings, longitude and latitude is woven into plain weave structure, and every bundle warp thread 1 is made up of 800 monofilament, 6 microns of every filament diameters, every bundle weft yarn 2 is made up of 800 monofilament, 6 microns of every filament diameters.The weaving process of glass cloth is constant, warp thread 1 and weft yarn 2 use the monofilament of this particular number and diameter, to change the composition form of electronics glass cloth inside, after the diameter of the intrafascicular monofilament of yarn is reduced into 6 microns from 9 microns of prior art, the surface area of yarn bundle increases, it is better to contain behind the resin pickup uniformity of tellite, thereby has promoted dimensional stability.
