Abstract

PURPOSE:To obtain the long bandlike base impregnated with resin without the air residual in the base by a method in which the temperature of said base is kept at higher temperature than that of resin varnish, and then the base is impregnated with resin varnish. CONSTITUTION:A long bandlike base is kept at higher temperature than that of resin varnish by 5-50 deg.C. When the temperature difference is less than 5 deg.C, the impregnation property is not improved, and when it exceeds 50 deg.C, the viscosity-unevenness of the resin varnish occurs. The heating of the long bandlike base is achieved by the conduction heating due to the contact with a heating roll, the base heating due to the blowing of hot blast or the base heating due to a dryer, etc.. The long bandlike base to be used is the woven cloth, the unwoven cloth or the mat composed of the inorganic fiber such as glass and asbestos, the organic synthetic fiber such as polyester, polyamide, polyaramide polyvinyl alcohol, polyaryl, etc., or the natural fiber such as cotton cloth. The base may be also made of paper, etc.. As the resin varnish, phenol resin, unsaturated polyester resin, fluorinated resin, etc., are used as single material, modified material or mixture. As impregnating means, dipping, spraying, coating, transferring, flow casting, etc., are used.

Conventionally, varnish impregnation of laminated boards and printed wiring board substrates has been carried out by dividing the impregnation process into primary and secondary stages in a layered manner as described in Japanese Patent Publication No. 52-45359 and Japanese Patent Publication No. 54-22471.
By primary impregnation with a low viscosity resin varnish, the air contained in the base material can be easily discharged to the outside of the base material, resulting in a resin-impregnated base material with 9 air content, which improves moldability and drillability. We are trying to obtain laminates and printed halves with good workability, but with glass cloth substrates, the disadvantage is that the resin varnish does not penetrate sufficiently between the intersections of the kasuri threads and weft threads of the glass cloth, and between the filaments that make up the gauze threads and weft threads. was there.

In the present invention, the temperature of the strip-like base material is 55% lower than the resin varnish temperature.
Because the method of impregnating the base material with resin varnish at a high temperature of ~50°C, it is possible to reduce the viscosity of the resin varnish at the interface where it contacts the glass cloth base material. Since the varnish can be permeated into the resin-impregnated base material, a resin-impregnated base material with no residual air inside the base material can be obtained.The present invention will be described in detail below.
