FIELD: ceramic industry.SUBSTANCE: invention relates to production of LTCC (Low Temperature Cofired Ceramics) thick-film multilayer switching boards and may be used during forming a pattern of functional layers on raw ceramic substrate. Raw ceramic substrate surface is coated with a solid layer of conducting or resistive paste and dried and then dried paste in spacing places of the pattern of board layer is removed with the help of laser beam which is moved along the surface of ceramic substrate by program in accordance with the topological pattern. Laser radiation power is selected so as to remove only applied paste and not to deform the substrate from crude LTCC ceramics.EFFECT: technical result is increased efficiency and accuracy of making LTCC boards, as well as shorter process cycle and lower cost of LTCC boards making.3 cl, 1 dwg |
