Filed: 1973-08-07
Abstract: 1404697 Printed circuits SIEMENS AG 7 Aug 1973 [11 Oct 1972] 37362/73 Heading H1R [Also in Division B6] A method of producing an electrical conductor path in a predetermined pattern on a ceramic substrate comprises producing the pattern in intaglio or relief on the surface of an unfired ceramic substrate by embossing, subsequently firing the substrate, and metallizing the raised or recessed parts forming the pattern either before, during or after firing. The recessed parts may be filled before or after firing with a pasty metal dispersion which is then sintered, any metal present on the raised parts being removed by an abrasive process such as sandblasting or grinding. Alternatively the entire surface may be coated with a thin metal film by applying a liquid metal dispersion by vapour deposition, atomization or spraying, the raised parts of the film are coated with lacquer resistant to electrolytic baths, and the exposed metal reinforced by electrolysis, the lacquer then being removed and the film removed from the raised parts by etching or sand-blasting. The resistant lacquer may be replaced by a solder stop lacquer and the exposed metal reinforced by coating with tin. If a refractory metal dispersion, e.g. molybdenum, uranium or platinum, is used for the film, the conductor paths can be produced in the form of metals having a high melting point, after the film on the raised parts has been removed, and sintering can be carried out simultaneously with firing. If the pattern is produced in relief, metallization can be carried out by rolling a metal dispersion, or by covering the recessed areas with a protective lacquer and then metallizing by vapour deposition or atomization, which may be followed by electrolytic reinforcement.
