The pH value of Bigely neutral tin plating process is nearly neutral, which is suitable for the plating of materials susceptible to acid, alkali influence or corrosion, such as special glass, ceramic materials as the substrate of the component solderable ends, leads. So, how should we maintain the plating solution in daily production?
When methanesulfonic acid tin plating additive is used, the acidity of the plating solution is relatively low, and the corrosion is relatively small. In the use of methylsulfonic acid tin plating additives, we can understand the advantages and disadvantages of additives through performance tests. The following takes the methylsulfonic acid tin plating additive Sn-819 from Bigely Technology as an example to conduct a performance test:
For the surface treatment workshop, the qualified and stable composition of the plating bath is the prerequisite guarantee of the surface treatment quality of the workpiece. The quality of electroplating can be guaranteed by managing the hard chromium bath well. Liquid composition information is the basis of liquid management, which can be used to effectively maintain and adjust the liquid, so that the components of the liquid have been stable and meet the requirements, laying the foundation for the stable surface treatment quality of the workpiece. The information of tank composition is obtained by chemical analysis, which is often called tank analysis.
In the pre-treatment stage of the plating process, conventional pickling processes (hydrochloric acid, etc.) are usually used to remove oxidized layers and rust from the surface of the workpiece. However, this process can lead to hydrogen embrittlement of the plated layer, which significantly affects the mechanical properties and service life of the plated product. Hydrogen embrittlement is a phenomenon in which the ductility and toughness of a material are significantly reduced in the presence of hydrogen, leading to an increase in its brittleness and susceptibility to fracture during use.
Zinc alloy die casting is easy to blister, which is a problem for many electroplating factories, because it is related to the straight-through rate of electroplating products, and will affect whether die-casting factory customers will continue to choose them. Therefore, it is very urgent to solve this problem. In this article, we will analyze the importance of pre-treatment wax and oil removal process for improving the binding force of zinc alloy coating.
In zinc-nickel alloy plating and passivation treatment, yellowing phenomenon often occurs at the corners and holes, which seriously affects the overall aesthetic and protective performance. In this regard, the application of Bigely Zn-323 zinc-nickel alloy trivalent chromium blue zinc passivator effectively solves these problems. Today's article will help you analyze the advantages of Zn-323 and its merits in practical applications.
