Zusammenfassung:The invention relates to a plating procedure for electrical contacts with silver based soldering alloy. In order to apply the procedure, the contacts bases are cleaned mechanically, degreased and pickled, then put on 0.1...0.3 mm thin plates of degreased soldering alloy in graphite trays. The trays with the contacts are charged in a furnace with reducing atmosphere at the melting temperature of the alloy, then discharged from the furnace to the ambient temperature. The plating of the electrical contacts by this procedure eliminates the pressing in double layer of the contacts and allows for the perfect welding, in arc, of the contacts on their support, thus reducing the consumption of precious metals.
