PRODUCTION OF PRINTING SCREEN, SCREEN PRINTING SUBSTRATE, AND SCREEN PRINTING PLATE USING SAID SUBSTRATE AND PRODUCTION OF PRINTED BOARD USING SAID PRINTING PLATE

摘要

PURPOSE: To produce a printing screen being hardly deformed or distorted, a screen printing substrate, and a screen printing plate, and to obtain a printed board using these. ;CONSTITUTION: A printing screen is made of a triaxial weave fabric, in which three yarns 1a, 1b, 1c are crossed with each other at an angle of 120 degrees at their intersections. A screen printing substrate is formed by providing a hot melt resin layer on said printing screen. In the production of a screen printing plate, a texitile printing pattern is formed on said screen printing substrate by the action of a laser. In the production of a printed board, a copper-clad laminate is processed into a printed board using said printing screen, said screen printing substrate, and said screen printing plate.;COPYRIGHT: (C)1993,JPO&Japio
