FIELD: ecologically clean technologies in radio engineering, electronic and other industries. SUBSTANCE: solution contains, g/l; nickel sulfate 59-185.5; sodium hypophosphate, 10-20; sodium acetate, 5-8; calcium hypophosphite, 34-102; and succinic acid, 1-3. Amount of nickel sulfate exceeds amount of calcium hypophosphite by 4-11% of stochiometric amount, solution becomes more stable and chemical nickel plating technology becomes simpler and working temperature and medium acidity ranges become wider. EFFECT: improved properties of the solution. 1 ex, 1 tbl
