Common Problems of Electroless Nickel Plating Bath Replenishment

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

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

2. The amount of nickel sulfate added to the electroless nickel plating solution (grams)=(27-2.7 times the EDTA titration number) and then multiplied by the cylinder opening volume L, the equivalent parameter value is the parameter value to be supplemented by nickel sulfate (in grams).

3. The parameter value of adding sodium acetate is obtained by multiplying the obtained nickel sulfate by 0.74, which is the parameter value of adding sodium acetate. Multiplying the amount of nickel sulfate by 0.37 is the supplementary parameter value of the additive. (The total of brightener A and complexing agent B, take half each). (unit milliliters) Lactic acid is the supplementation of nickel sulfate. Multiply the number by 0.185 (in milliliters).
