やプリント配線用基板として使用されている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a single-sided metal foil-clad laminate with a small amount of warpage. - A laminate made of paper, crow cloth, crow paper, etc. as a base material, which is laminated with multiple resin-impregnated base materials impregnated with a resin liquid and cured, and a metal foil on one or both sides of the laminate. Metal foil-clad laminates made by pasting these together are used as insulating boards and printed wiring boards.

−98136号等参照。Conventionally, these laminates have been manufactured using a batch method in which the base material is impregnated with resin varnish and dried, then the resulting bristle rugs are layered and molded by pressing and heating in a press, but recently, long base materials have been A continuous method has been developed that performs resin impregnation, lamination, curing, etc. while continuously conveying, and is attracting attention. For example, Japanese Patent Application Laid-Open No. 55-4838 by the present applicant. Same 56
See No.-98136, etc.
上記の方法等により製造される片面金属箔張り積層板は
それを構成する材料の熱膨張係数の差や硬化性樹脂の硬
化収縮に伴い反りを生じやすい。A single-sided metal foil-clad laminate manufactured by the above-mentioned method or the like tends to warp due to differences in thermal expansion coefficients of the materials constituting it or due to curing shrinkage of the curable resin.
この反りは通常3本ロールよりなる反り矯正装置を通過
させ、反りと反対方向に積層板をたわまゼることによっ
て矯正することができる。This warp can be corrected by passing the laminate through a warp straightening device, which usually consists of three rolls, and bending the laminate in the opposite direction to the warp.
しかしながら3本ロールを通ず方法によっては積層板全

することは不可能であった。However, although it is possible to correct the curvature of the entire laminate depending on the method of passing it through three rolls, for example, it is difficult to correct the difference in local warpage between the edges and the center in the width direction of the laminate. It was impossible.
本発明はカミる問題を改良し、積層板内の特に幅方向で
の反りのバラツキの少ない片面金属箔張り積層板を連続
的に製造する方法に関する。The present invention relates to a method for continuously manufacturing single-sided metal foil-clad laminates that improves the problem of curling and has less variation in warpage within the laminate, particularly in the width direction.

る。In other words, a plurality of sheet-like base materials are impregnated with a curable resin while being conveyed continuously, the impregnated base materials are laminated, and metal foil is laminated together. After continuous curing, one side is cut to a predetermined size. In the continuous production method of metal foil-clad laminates, the laminate after curing is forcibly deformed in the opposite direction to the warp direction by changing the curvature at the center and edges in the width direction, thereby correcting the warp. This is a continuous manufacturing method for single-sided metal foil-clad laminates.

Vinyl ester resins and epoxy resins are preferred. As the base material, any material commonly used in the production of laminates, such as paper, glass cloth, and glass paper, can be used. As the metal foil, electrolytic copper foil, rolled copper foil, iron foil, aluminum foil, etc. are used, but electrolytic copper foil is most preferred.

ない。The process up to curing of the laminate is described in the above-mentioned Japanese Patent Application Laid-Open No. 55-4.
838. It can be carried out in exactly the same manner as the method described in JP-A-56-98136 and the like. The process of correcting warpage in the present invention may be performed either before or after the length cutting device that cuts the laminate into predetermined dimensions, but it is carried out continuously in the section from the exit of the curing furnace to the length cutting device. is the most efficient, and the amount of warp in the resulting laminate is also small. Further, if necessary, warpage may be corrected at multiple locations.
反りの矯正装置の一例を第1図に示す。An example of a warpage correction device is shown in FIG.
1は下側のバックアンプロール、2は上側から積層板を
バンクアップロールの形状に沿わせるように押しつける
ための押さえロールである。この例では積層板3の上側
に金属箔が貼り合わされており、押さえロール2の接触
部の材質は金属箔よりも軟らかい硬度を有するゴム等を
用いることが、金属箔に傷をつけないために望ましい。Reference numeral 1 denotes a lower back-up roll, and 2 a presser roll for pressing the laminate from above so as to follow the shape of the bank-up roll. In this example, metal foil is bonded to the upper side of the laminate 3, and the contact part of the presser roll 2 should be made of rubber, etc., which has a softer hardness than the metal foil, in order to avoid damaging the metal foil. desirable.
積層板の硬化の過程において、端部の方が中央部に比べ
て金属箔面を凸にした反りがやや大きい傾向があるため
、これを矯正し、幅方向での積層板内の反りのバラツキ
を少なくする目的で、下側のバックアップロールの形状
は両側の径が太くなるような鼓状のロールとしている。During the curing process of the laminate, there is a tendency for the edges to have a slightly larger warp than the center, which is caused by the convex metal foil surface. In order to reduce this, the lower backup roll is shaped like a drum, with diameters increasing on both sides.

反りが元に戻る傾向がある。In addition to the method shown in Figure 1, there is a method of forcibly deforming and correcting warpage by changing the curvature at the edges and the center, for example, as shown in Figure 2, a single piece that is paired with a back unroll is used. The curvature of the laminate can be corrected by using drum-shaped rolls, or by sandwiching the metal foil-clad laminate between a pair of narrow rolls as shown in Figure 3, and using at least two or more sets of rolls to correct the curvature of the laminate. A method of correcting the warpage by changing the warpage, or a method of combining the press roll shown in FIG. 2 and the backup roll shown in FIG. There is a method of omitting a part of the curvature, a method of passing through a slit having a predetermined curvature shape, etc., and any method may be used. Alternatively, a combination thereof may be used. The temperature of the laminate when correcting warpage is 100℃.
C or lower, preferably room temperature to 80C, is effective. When the temperature of the laminate exceeds 100°C, the corrected warpage tends to return to its original state.
