となっていた。Conventionally, resin is supplied in a mixing tank by adding a solvent while stirring with measuring with a viscosity meter, adjusting the amount of solvent input and controlling the viscosity, then supplying the resin varnish to the impregnation tank, or directly Although the resin varnish is supplied to the material, it was inevitable that air bubbles were mixed in the resin varnish and uneven viscosity was generated in this method. In recent laminated boards and printed wiring boards, there is a strong demand for a resin-impregnated base material that does not have built-in bubbles or resin unevenness, because it is extremely disliked by the decrease in reliability of electric circuits due to built-in bubbles and resin amount variations. For this reason, it is necessary that the resin varnish supplied to the resin-impregnated base material long-length base material does not contain air bubbles or viscosity unevenness.

Always use, evaporate, replenish the amount of solvent that scatters, and when the viscosity of the resin varnish increases due to external conditions such as changes in the ambient temperature on the discontinuous supply line and changes in the line speed during the resin impregnation process, etc. A constant amount of solvent is supplied only during the time of one circulation in the circulation line.

Discontinuous solvent supply line 6
In this case, the discharge amount adjusting valve 3'is equipped with an automatic valve device 8 for supplying a constant amount of the solvent for a certain amount of time, the viscosity of the resin varnish increasing due to an external condition, so that the resin varnish viscosity of the resin varnish circulation supply line is constantly maintained. It has become stable. Therefore, since the stirrer is not used at all, it is possible to obtain a resin-impregnated base material having a uniform impregnation state without containing bubbles. Incidentally, in the resin supply device of the present invention, it is preferable to control the entire temperature in terms of viscosity control, a solvent tank, a continuous constant amount supply line,
The temperature of each of the discontinuous supply line and the resin varnish circulation supply line may be individually adjusted, or the whole may be arranged in the temperature adjustment chamber.
