ンケ樹脂表面に形成する。Conventional-2 printed wiring boards are made by forming a synthetic resin layer on a substrate such as paper-phenol resin, paper-epoxy resin, or iron plate by dipping the substrate in a resin liquid or applying powdered resin. This resin is then cured. Then, in order to roughen the surface of the cured resin, it is immersed in an aqueous solution of chromic acid and sulfuric acid. After the surface has been roughened, metal plating is applied by electroplating or chemical coating to form a predetermined pattern on the resin surface.

Immerse in acid solution. The temperature of this liquid during immersion is 50~
The temperature is 40°C and the immersion time is 10-15 minutes. Next, the substrate was taken out from the etching solution, washed with water, and treated with sodium monochromate 20'/1 and fluoroboric acid 240f.
Sodium chromate powder, consisting of t/, is immersed in an aqueous solution of boronic acid. The liquid temperature at this time was 40℃, Mani! The time is 15-20 minutes. After performing these roughening treatments, electroless copper plating is applied to the substrate to form a predetermined circuit.

酸系水溶液のみの場合のほぼ2倍以上の密着力である。It can be finely etched with a sodium chromate-7-fluoroboric acid aqueous solution. For this reason, the metal plating formed after this has many surfaces that are in contact with the synthetic resin unevenly (as a result, the metal plating on the synthetic resin layer has almost twice the adhesion strength of the conventional chromic acid-sulfuric acid-based aqueous solution only). be.
