Abstract
1,175,282. Etching. FERRANTI Ltd. 8 July, 1968 [8 Aug., 1967], No. 36259/67. Heading B6J. [Also in Division H1] A multiple-layer printed circuit comprising alternate layers of printed-circuit board and epoxy resin-impregrated glass fibre sheets is etched in a solution of sulphuric acid in water to remove excess epoxy resin from around holes drilled through the circuit, and then immersed in a solution of a cationic surface-active agent in a suitable solvent. The surface active agent may be a quaternary ammonium salt, e.g. cetyl pyridinium bromide, tetradecyl pyredinium bromide or cetyl trimethyl ammonium bromide. The solvent may be water or trichloroethylene.
