The short life cycle of electroless nickel plating solutions is due to the multiple challenges and constraints they face in plating solutions.
The most important components in a electroless nickel plating solution include a nickel source, a reducing agent, a pH adjuster, and various ligands and stabilizers. As the reaction proceeds, the depletion of the major plating solution components results in changes in deposition rates and a reduction in the quality of the plated layer. For example, phosphorus levels increase with time, which alters the chemistry of the bath and can cause slower deposition rates and less uniform plating quality.
In addition, due to the autocatalytic nature of the deposition process, by-products such as organic decompositions and slag may be formed in the plating solution, which can be adsorbed to the surface of the workpiece and affect the uniformity of deposition.
The stability of the plating solution is another key factor limiting cycle time. When the stability of the bath is poor, some of its components may undergo destabilizing decomposition, especially at higher temperatures or incorrect pH.
Stabilizers and buffers are added to extend the service life of the bath, but long-term use can cause these additives to fail. In addition, impurities brought in by the workpiece will gradually accumulate in the plating solution, further affecting the performance of the plating solution.
Therefore, the interaction of several factors in the electroless nickel plating solution leads to a reduction in the performance of the solution (in which the synergistic effect of additives is more important), thus shortening the service life.
In order to maintain the performance of the plating solution and extend its service life, we need to use Bigely electroless nickel concentrate (the ratio is reasonable, can play a good synergistic effect), only need to be analyzed periodically, according to the instructions of the proportion to replenish the corresponding concentrate components can be used for normal use of 10-12 cycles.
