Common Problems of Electroless Nickel Plating Bath Replenishment

Now let's interpret electroless plating for usnickelFrequently asked questions about bath supplementation, if you want to know friends, let's take a look at the content of the article below.

1. First take 100 ml of deionized water, then add 10 ml of plating solution, add 10 ml of ammonia water, 0.02 g of purpuric ammonia indicator, and finally titrate with 0.1 mol of EDTA solution to purple as the end point.

2. The amount of nickel sulfate added to the electroless nickel plating solution (g)=(27-2.7 times the EDTA titration number) and then multiplied by the cylinder opening volume L, which is equal to the parameter value that the nickel sulfate needs to be supplemented with ( unit gram).

3. The parameter value of adding sodium acetate is obtained by multiplying the obtained nickel sulfate by 0.74, that is to say, the parameter value of adding sodium acetate. (unit gram) The parameter value of adding additive to electroless nickel plating solution is obtained by using Multiplying nickel sulfate by 0.37 is the value of the supplementary parameter of the additive. (The sum of brightener A and complexing agent B, each takes 1\/2). (unit ml) lactic acid is the supplement of nickel sulfate. Multiply the addend by 0.185 (in ml).

The above is the content of the relevant electroless nickel plating that is explained to us now, and I look forward to providing us with a little help.
