Coming technology

Conventionally, the following method has been known as a method for producing such a conductive circuit *. In other words, metal skins such as gold, brass, stripes, moths, ¾ / kel, palladium, etc., gold skins such as indium oxide, indium oxide, antimony oxide, etc. are deposited by vacuum evaporation, spay. * To be formed on the entire surface of glass substrate, plastic base plate, etc. by tarring method or printing method A mask is formed on the surface of the conductive circuit by a photoresist or screen printing method, and then an unnecessary gold or leather oxide or a metal oxide skin by a dry etching method. after removal of the minute, more before 12 masking eyebrows have ^ O connexion desired electrical «resistance circuit in removing *扳a method for manufacturing there ¾ _beta

However, such a method requires many steps such as masking eyebrow formation, etching, masking employment removal, and the like, and is extremely highly collective.

As a method of digging the dots during the beautic method, it is disclosed in Japan S, Machikai Sho 56- 1 3 7 89, Ko-Tokusho 581 1 1 3 3 7 6 Kogo, etc. A broken method has been proposed. All of the methods of :: are printed on the substrate, ift are removed by erosion, and the ink containing the conductive agent of the 35 conductive chine is printed on the new surface. After eating the unnecessary 15 minutes of the lead, it removes the ink component containing the SITiSW food, thereby producing a new color that has a new conductive circuit.

According to this method, formation of a masking layer and removal of masking debris are performed. This process has a great effect in that there is no need for a process, and there is a small number of drug-making processes. However, although this method has a good effect in that the number of working steps is small, it is unreasonably improper for Sosei Roh. This is because, in any of the above-mentioned methods, the caustic agent to be used is usually in a liquid state. After printing the ink containing the food, the caustic agent is used as it is, that is, on the JR. The printed ink must be transferred to the next type, Etchinge S, the process of removing foreign substances without causing any contact with other parts. Therefore, printing is performed while rapidly winding up the substrate. the it is not possible that the line now _β
