2. Description of the Related Art As a printed circuit board, a non-woven glass fabric is used as an intermediate layer base material, a woven glass fabric is used as a surface layer base material, and a composite laminated board impregnated with an epoxy resin and heat-pressed is formed.
Conventionally, a prepreg obtained by impregnating a glass nonwoven fabric with a resin for an intermediate layer and dried and a prepreg obtained by impregnating a glass woven fabric with an epoxy resin and dried are individually manufactured, and then they are stacked and heated and pressed to be manufactured. However, in order to individually manufacture the prepreg, each coating device and an operator are required, and a step of stacking a plurality of them is also required. Further, since the varnish having a large amount of solvent is dried to convert the resin to the B stage, a large amount of volatile solvent is discharged to the atmosphere, and a large amount of energy is consumed, which is not preferable because it has a high environmental load.

In order to solve these problems, a batch coating method has recently been proposed. That is, in the production of a composite laminate, first, a glass woven cloth is coated with an epoxy resin varnish having a small amount of solvent, then a glass nonwoven fabric is laid on the epoxy resin coated surface, and further, an intermediate layer having a small amount of solvent is formed on the glass nonwoven fabric. In this method, a layer resin is applied and dried by heating to prepare a prepreg, and finally two prepregs are stacked with the glass nonwoven fabric surface inside and heated and pressed to produce a laminated plate. However, these methods also require a step of superimposing two prepregs before heat and pressure molding.

The present invention has a step of applying the epoxy resin (a) to one surface of the glass woven cloth. Examples of the epoxy resin (a) used in the present invention include bisphenol type epoxy resin and novolac type epoxy resin. Among these, bisphenol A type epoxy resin is preferable. This can improve the adhesion to the copper foil.
Also, the cost can be reduced. The epoxy resin (a)
Is not particularly limited, but is preferably applied as a varnish. This improves the impregnation property into the glass woven fabric. The varnish is not particularly limited, but the resin solid content is preferably 35 to 85% by weight of the entire varnish, and particularly 40
˜70 wt% is preferred. If the resin solid content is less than the lower limit, the amount of impregnation into the glass woven fabric may decrease,
If it exceeds the upper limit, the viscosity may be too high and the impregnating property may be lowered. Further, as the glass woven fabric used in the present invention, a general one can be used.

The epoxy resin (a) is not particularly limited, but is 50 to 150 per 100 parts by weight of the glass woven fabric.
It is preferable to apply by weight, and particularly preferably 60 to 130 parts by weight. When the coating amount is less than the lower limit value, the adhesion with the intermediate layer epoxy resin (b) or the glass nonwoven fabric may be reduced. When the amount exceeds the upper limit, the resin content becomes excessive, and the heat characteristics of the laminate may deteriorate. The epoxy resin (a) can be applied by, for example, a comma roll coater, a knife coater, a die coater, a reverse coater or the like. Of these, a comma roll coater and a knife coater are preferable.

In the present invention, after the above step, there is a step of applying the intermediate layer epoxy resin (b) to the glass nonwoven fabric. Thereby, the productivity can be improved as compared with the case where the glass woven fabric and the glass nonwoven fabric are separately impregnated with the epoxy resin. Examples of the intermediate layer epoxy resin (b) used in the present invention include bisphenol type epoxy resin and novolac type epoxy resin. The intermediate layer epoxy resin is not particularly limited, but is 80 to 150 relative to 100 parts by weight of the epoxy resin (including a curing agent).
It is preferred to include parts by weight of filler, especially 90-14
0 parts by weight is preferred. This can reduce the coefficient of thermal expansion. Furthermore, dimensional stability can be improved.
