[0008] 1. Formula: nickel sulfate 22g / L, sodium hypophosphite 25g / L, sodium acetate 12g / L, malic acid 6g / L, acetic acid 8ml / L, lactic acid 10ml / L, bismuth sulfate 4 mg / L, celandine Amino acid 1 mg / L, o-phenanthroline 2 mg / L, sodium dodecylsulfonate 1 mg / L, copper sulfate 1 mg / L, pH 4.5, loading 0.72, plating temperature 80°C, The plating time was 10 minutes.
[0009] 2. Preparation of plating solution
[0010] (1) Weigh out the calculated amount of various drugs according to the volume of the plating solution;
[0011] (2) Ionized water or distilled water completely dissolves solid medicines and dilutes viscous liquid medicines into dilute solutions.
[0012] Nickel Italian sulfate is mixed and dissolved with sodium acetate, malic acid, acetic acid, and lactic acid first, and then mixed with sodium hypophosphite; and the amount of operating water is controlled at about 3 / 4 of the volume of the configured solution and cannot exceed the specified volume.
[0013] (3) Adjust t...
