Acid bright tin plating is an important process widely used in the manufacture of electronic, electrical and communication equipment. However, in the actual production process, we often encounter the phenomenon of whitening of plating, which not only affects the aesthetics, but also may adversely affect the functionality. So, what are the reasons for the whitening of the plating layer and how to solve it?
Semi-bright nickel plating is a very common type of nickel coating in the plating industry, which is intermediate between bright nickel and non-glossy (matte or dull nickel), and is intended to provide a surface coating that meets certain mechanical and industrial performance requirements while also having a certain aesthetic appeal. Typical characteristics of semi-bright nickel include a more uniformly smooth surface and a moderately light-reflective gloss, but not as highly reflective and mirror-like as bright nickel.
Bright nickel plating is an important surface treatment process, widely used in electronics, electrical appliances, automotive parts and other fields. The stability of bright nickel plating solution is the key to ensure the quality of plating. However, in practice, bright nickel plating solution often appears unstable phenomenon, resulting in poor plating quality, and even shorten the service life. In this article, we will analyze the reasons for the instability of bright nickel plating solutions from several main angles, and introduce how to use Bigely bright nickel plating brightener Ni-301 to cope with these problems.
In the copper-nickel-chromium plating process, bright acid copper plating plays an important role, and if the quality of the copper plating layer is not up to standard, it will often have a certain impact on the subsequent plating. Therefore, it is necessary to study the causes and solutions of streaks on bright acid copper plating. In this issue, we will first talk about the influence and removal of organic impurities and oil impurities.
Irregular biting or leakage of aluminum workpieces after micro-etching treatment, as well as the phenomenon of poor bonding after plating, are important problems that plague many plating masters. These problems directly affect the surface quality of the workpiece and plating effect, the reason is mainly due to the surface of the workpiece on the oil and oil film cleaning is not complete.
In the electroplating process, degreasing is of great importance as a key pretreatment process. However, many electroplating factories often have to face a troublesome problem when electrolytic degreasing: frequent smoke and irritating odor during operation. These phenomena not only bring health hazards to the operators, but also seriously affect the environmental quality of the workshop. In this article, we will discuss the causes and solutions of this problem in depth, and provide suitable improvement measures for electroplating plant owners.
