МИ 1222.9

TirasLam MI 1222.9

TirasLam MI 1222.9 (type FR-4), is made on the basis of glass fabric and two-functional brominated epoxide resins. Special additive attaches a material ability to block UV-radiation and to radiate in visible range of a spectrum.

Application

МИ 1222.9 has a series of essential advantages before usual materials such as FR-4: UV blocking provides absence of the double image at production of printed-circuit-boards, and the luminescence allows to carry out the operative control of a surface and interior layers of printed-circuit-boards, and also quality of printed-circuit pattern with high contrast.
