What factors interfere with electroless nickel rate

Electroless platingnickelThe process technology is widely used in the field of metal manufacturing due to its excellent metal surface processing technology. The rate of chemical nickel has a great influence on the high efficiency of product production. So what factors will interfere with the rate of chemical nickel? Let's take a look.

1. Temperature. Increasing the temperature of the plating solution will accelerate the nickel plating rate, but the reliability of the plating solution will decrease and the service life will be shortened. At the same time, the volatilization rate of ammonia is accelerated, which increases the stimulus to the actual operation, and the pH value in the plating solution decreases rapidly. Adjust often.

2. Concentration value. Under the standard that the pH value of the alkaline nickel plating solution is relatively stable, the nickel ion concentration of electroless nickel is basically irrelevant, but mainly depends on the concentration value of hypophosphite. When the hypophosphite increases double , the nickel plating rate is also doubled.

3, pH value. The nickel plating rate increases with the increase of pH value, but the pH value should not be too high, otherwise the reliability of the plating solution will be reduced.

4. Load capacity. Similar to electroless copper plating, if the load is too much, the nickel plating rate decreases rapidly. If the load is too low, the nickel plating rate is too fast, and the reliability of the nickel plating solution decreases.
