According to the present invention, a plurality of base materials including at least two glass cloths are continuously conveyed in parallel and the base materials are individually impregnated with a curable resin solution, and the impregnated base materials are laminated and united. Then
In a continuous manufacturing method of a glass cloth reinforced electrical laminate, which comprises laminating a cover sheet and / or a metal foil, continuously hardening it, and then cutting the same, using a glass cloth raw material with little bending and using a glass cloth base during transportation. By controlling the tension and meandering correction of the material appropriately and preventing the impregnated resin from being locally unevenly distributed, the glass cloth base material is conveyed while suppressing the bending of the glass cloth base material to 20 mm / m or less. The present invention provides a continuous production method of a glass cloth reinforced electrical laminate.

Preferred Embodiment Here, the warp of the glass cloth means that the intersecting angle of the warp yarn and the weft yarn is deviated from 90 °, and the amount of the warp is defined by how many mm the weft yarn deviates from the orthogonal position on the warp yarn at the maximum. means. Therefore, for example, when the weft thread is linearly displaced, it is the amount of displacement between the ends of the weft thread,
If the weft is bent due to liquid pool, etc.,
It is the distance in the warp direction between the end of the weft thread and the curved apex.

In addition, the twist of the laminated plate according to JIS C 6481.5.4 has a strong correlation with the amount of warp, and the actual quality problem is when the difference between the maximum twist amount and the twist amount in the perpendicular direction is large. Yes, if the difference is small, it is possible to correct the twist by a correction method such as warping, but if the difference is large, it is difficult to correct. Therefore, the twist amount in the present invention is defined as the difference in the warp amount in the diagonal direction.

According to the present invention, in order to suppress the bending of the glass cloth to 20 mm / m or less, it is necessary to select a glass cloth having a small amount of bending itself. Even if such a raw material having a small amount of bending is used, the bending may occur during the transportation, so it is necessary to suppress the amount to 20 mm / m or less. There are several methods.

In the continuous method, the substrate is conveyed by applying tension in the conveying direction. If this tension is small, it is easy to meander, and if it is large, bending is likely to occur. It is necessary to some extent to prevent meandering, but excessive tension should be avoided as it will bend the eyes.

Further, in order to correct the meandering of the base material, it is customary to install one or more EPC devices (edge, position, controller) between the feeding of the base material and the stacking,
If the meandering is abruptly corrected, the glass cloth is likely to be bent, so that the EPC feeding speed is slowed down, the holding angle of the EPC roll is reduced, and the EPC device is installed at two or more places. Rather than making a gradual correction, it suppresses the occurrence of eye bending.

A large amount of the applied resin liquid is locally unevenly distributed, and when a liquid pool is formed, eye bending is likely to occur. Therefore, apply the resin liquid evenly and without excess or deficiency, narrow the pitch between the rolls supported by the base material, give an upward slope to the transfer path of the base material from the coating part to the laminating part, and add excess resin. It is necessary to take measures such as allowing the liquid to flow down.

By using these means in combination, the bending of the glass cloth is 20 mm / m or less, preferably 10 mm / m.
Hereafter, it can be suppressed to 5 mm / m or less, more preferably. If the amount of warp exceeds 20 mm / m, the product will be greatly twisted and difficult to correct later.
