In the application process of nickel sulfamate additives, the internal stress of the plating layer is a crucial performance indicator, which is not only related to the hardness and ductility of the plating layer, but also directly affects the bonding of the plating layer with the substrate and the overall quality of the plating layer. Among the many influencing factors, the PH value of the plating solution is a key factor that cannot be ignored.
Direct effect of PH on the internal stress of the plated layer
The pH value of the plating solution has a significant effect on the internal stress of the plating layer. When the pH value of the plating solution increases, the local pH value near the cathode will further increase due to the hydrogen precipitation phenomenon, and it is easy to produce nickel hydroxide particles interspersed in the plating layer. The presence of these particles increases the internal stress of the plated layer, which makes the plated layer more prone to cracking and peeling. Therefore, in order to obtain a low-stress plating layer, the pH value of the plating solution must be strictly controlled in the appropriate range, e.g., 3.5-4.5, which is one of the recommended operating conditions for Bigely nickel sulfamate additive Ni-1000.
Why use Bigely nickel sulfamate additives
Bigely nickel sulfamate additive Ni-1000 is widely used in electronic parts, terminals and high-speed plating. By adding Ni-1000 to the plating solution, the internal stress of the plated layer can be reduced and the ductility and bonding strength of the plated layer can be improved, thus ensuring stable and reliable quality of the plated layer.
