することにある。As described in the conventional technology, when the inner layer steel foil of a multilayer wiring board is treated with chlorite), the acid resistance and adhesion of the copper foil decreases, and when the inner layer copper foil is treated with 11 um persulfate, the copper foil loses its acid resistance and adhesion. There was a problem in that the soldering heat resistance and adhesiveness of the copper foil deteriorated. Furthermore, epoxy resin multilayer wiring boards generally have a problem of poor smear resistance. The present invention has been made in view of the above-mentioned problems in the conventional technology, and its purpose is to improve the acid resistance, adhesion, and solder heat resistance of the inner layer steel foil, and to improve the acid resistance, adhesion, and solder heat resistance of the inner layer steel foil, which has been previously used in epoxy resin multilayer wiring boards. Another object of the present invention is to provide a method for manufacturing a multilayer wiring board with improved smear resistance.

The method for dipping a multilayer wiring board is described above, which is characterized by coating with a synthetic resin of 0.5 Wit% (hereinafter referred to as "Ton") and then integrating it with the outer layer material through a resin-impregnated base material. The present invention has been achieved and will now be described in detail.

。In the present invention, copper foil is treated with a mixed solution of 11 um persulfuric acid and sodium hydroxide, and treatment solutions other than the mixed solution do not roughen the treated surface or make it too coarse. It is impossible to improve acid resistance, connectivity, and soldering heat resistance. There are no particular limitations on the concentration of the mixed solution, treatment temperature, treatment time, etc. Next, the treated surface of the inner copper foil is covered with a synthetic resin such as a chlorine-containing bolt O~o, OS4 7 enol resin, epoxy resin, unsaturated Bo-11 ester resin, Bo-11 imide resin, fluorinated resin, etc. .

The required number of sheets is made by impregnating and drying base materials such as marito, net, cheesecloth, and paper so that the amount of resin after drying is 40 to 60%. It is something to intervene. The chlorine content of the resin impregnated base material is also 0 to 0. It is more preferable to set it to os%. Outer layer materials include copper foil, aluminum foil, and aluminum foil.
A metal foil such as Kel foil or a 4-layer gold-clad laminate on one side is used. The laminating and integrating means may be any suitable laminating means such as a press, roll, double belt, etc., and is not particularly limited.
