Description

(54) PHYSICAL SILVER APPLICANT

The invention relates to physical silver products and can find a change in the manufacture of photo masks (electronic industry), including photo masks of printed circuit boards (radio industry), nets, scales, the world of optical instrument limbs and other parts of optical instrumentation and, finally, in such The fields of technology, where the need arises for the selective (selective) W1I non-selective (non-selective) deposition of the noble metal (silver) on the surface of the dielectric. The weight of silver kyL is a physical developer, including silver nitrate, citric acid, metol, a surface active substance (surfactant), for example, dodeclamine acetic acid (ormoc- 12U), and water 1.
