【発明の詳細な説明】
本発明は、エアージエツト方式の織機により織
られたガラスクロスを基材として用いた銅張積層
板の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a copper-clad laminate using glass cloth woven by an air jet type loom as a base material.
一般にガラスエポキシ銅張積層板のようなガラ
ス基材銅張積層板においては、補強用の繊維質基
材として従来からエアージエツト方式の織機によ
り製造されたガラスクロスが使用されている。 Generally, in glass-based copper-clad laminates such as glass-epoxy copper-clad laminates, glass cloth manufactured by an air jet type loom has been conventionally used as a reinforcing fibrous base material.
このエアージエツト方式の織機および織り方
は、緯糸を一方向から、経糸の上および下を交互
に通し、一本ごとに、端部をそろえて切断するも
のであり、緯糸を経糸の上および下を通しながら
往復させてゆく通常のシヤトル方式の織り方に比
べ、生産能率が高く織り上がつた製品によごれや
欠陥が少ないという利点をもつている。 In this air jet type loom and weaving method, the weft threads are passed from one direction alternately above and below the warp threads, and each thread is cut with the ends aligned. Compared to the normal shuttle method of weaving, which involves weaving back and forth while threading, it has the advantage of higher production efficiency and fewer stains and defects in the finished product.
しかしながらこのようなエアージエツト方式で
製造されたガラスクロスは、図面に示すように、
多数の経糸１と直角に交叉しこれらを織り上げて
ゆく緯糸２の両端部３が切断端となるためフエザ
ー状のエツジを形成し、そのためこれを用いて銅
張積層板を製造する際作業性が極めて悪いという
欠点があつた。 However, as shown in the drawing, glass cloth manufactured using such an air jet method has the following characteristics:
Both ends 3 of the weft 2, which intersects a large number of warps 1 at right angles and weaves them together, become cut ends, forming feather-like edges, which improves workability when manufacturing copper-clad laminates using these. It had a very bad flaw.

装置にひつかかつたり、プリプレグの積重がしに
くい、或いはこの端縁部が折れたりしやすいとい
う欠点があつた。 In other words, to manufacture copper-clad laminates, glass cloth is impregnated with resin varnish and dried, semi-cured prepreg and copper foil are layered together and integrated by heating and pressure forming. Excessive resin varnish adheres to the edges, forming feather-like edges on the prepreg, which can get caught in automated conveyor rolls and other devices, making it difficult to stack the prepregs. Another disadvantage is that the edge portions are prone to breakage.
本発明はこのような欠点を解消するためになさ

この部分の樹脂量を減少させることを特徴とする
銅張積層板の製造方法に関する。 The present invention was made to eliminate such drawbacks, and after impregnating the prepreg with resin varnish, a predetermined amount of solvent is dropped onto the feather edge portion of the prepreg.
The present invention relates to a method for manufacturing a copper-clad laminate, which is characterized by reducing the amount of resin in this portion.

が適している。 In the present invention, as the resin varnish to be impregnated into the glass cloth, any resin varnish that is generally used for impregnation, including phenolic resin varnish and epoxy resin varnish, can be used, but in particular, epoxy resin varnish can be used. Varnish is suitable.
またこれらの樹脂ワニスの粘度は含浸の作業性

〜40センチポイズの範囲とする。 In addition, the viscosity of these resin varnishes is preferably 5 to 100 centipoise from the viewpoint of impregnation workability, etc.

ｍ未満では滴下の効果があまりなく、反対に0.1
c.c.／１ｍを越える場合には、エツジ部より内側の
樹脂濃度も低くなつてしまい、安定した特性の積
層板が得にくいためである。 In the present invention, an organic solvent such as acetone, methyl ethyl ketone, or methyl cellosolp is continuously applied to the feather edge portion of an undried prepreg obtained by impregnating glass cloth with such a resin varnish at a rate of 0.01 to 0.1 cc per 1 m of one side. The amount of resin that is impregnated and adhered to this area is reduced. The reason for setting the preferable dropping amount of the solvent in this range is that the solvent amount is 0.01cc/1.
If it is less than 0.1 m, the effect of dropping is not so great.
This is because if it exceeds cc/1m, the resin concentration inside the edge portion also decreases, making it difficult to obtain a laminate with stable characteristics.

Mold and integrate for 60-120 minutes.
