脂ワニスが充分浸透しない欠点があった。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.

It is a combination base material etc. Resin varnishes include phenolic resin, cresol resin, epoxy resin, unsaturated polyester resin, melamine resin, polyimide, polybutadiene, polyamide, polyamideimide, polysulfone, polyphenylene sulfide, polyphenylene oxy V1 polybutylene V phthalate polyether ether ketone, Fluorinated resins, etc. alone, modified products, mixtures, etc. are used, and if necessary, a solvent such as water, methyl alcohol, acetone, cyclohexanone, styrene monomer, etc. is added to adjust the viscosity.Long strip-shaped base material The temperature needs to be 5 to 50 degrees Celsius higher than the resin varnish temperature.In other words, impregnating properties will not improve if it is not dropped at 5 degrees Celsius, and if it exceeds 50 degrees Celsius, viscosity unevenness will occur in the resin varnish. Heating of the long strip-shaped base material can be carried out by heat transfer heating by contact with a heating roll, heating the base material by heating the base material by blowing hot air, and heating the base material by a dryer, and is not particularly limited. .
