Abstract

The invention relates to the technology for electrochemical application of functional platings and may be used in the radioelectronic industry.Summary of the invention consists in that the process includes the electrochemical deposition of coating from electrolyte containing nickel chloride, tin chloride, potassium pyrophosphate and subsequent thermal treatment, the electrolyte additionally containing ammonium tartrate, dimethylaminoborane and thallium nitrate, in the following component ratio, g/l:nickel chloride NiCl2(2H2O 1�0,0...15,0tin chloride SnCl2(6H2O �10,0...12,0potassium pyrophosphate K4P2O7 120,0...140,0ammonium tartrate C2H4(OH)2 (COONH4)2 �5,0...15,0dimethylaminoborane (CH3)2 NBH2 �1,5...2,5thallium nitrate TlNO3 ��0,001...0,010,the deposition is carried out at pH=8,5...10,5, the temperature of 50...70C and the current cathodic density of 0,5...2,0 A/dm2, and the subsequent thermal treatment of the plating at 120...150C during 0,5...1 hour.The result of the invention consists in increasing the electrolyte stability, improving the appearance of the platings and providing a high degree of soldering of the radioelectronic equipment elements with quick solders.
