In the high-speed tin plating process with methanesulfonic acid, burnishing of the plated layer is a common problem, which not only affects the aesthetics of the plated layer, but also may lead to a deterioration of the performance of the plated layer. As a R&D and sales engineer for continuous bright tin plating additives, I will discuss in depth the causes and solutions of layer burnout, with special reference to the advantages of Bigely continuous bright tin plating additive Sn-839 in solving this problem.
Bigely high phosphorus electroless nickel additive Ni-811 is a product with good corrosion resistance, neutral salt spray test in more than 168 hours, and resistance to nitric acid test 5min basically does not change color. So, how is its corrosion resistance so good?
In the field of electroplating, black zinc passivator is widely used to enhance the corrosion resistance of zinc plating. Salt spray testing is one of the most important methods to measure the corrosion resistance of a coating. In this article, we will discuss in detail several key factors affecting the salt spray capability when using black zinc passivators, with special reference to why Bigely black zinc passivator BZ-216 performs so well in the salt spray test.
In the electroplating industry, tin plating of the surface of copper rows is a common process used to enhance the corrosion and oxidation resistance of copper rows. However, when using tin plating brightener, white haze sometimes appears on the surface of copper rows, which not only affects the aesthetics of the plated layer, but also may affect the physical and chemical properties of the plated layer. As a R&D and sales engineer of tin plating brightener, I will analyze the causes of this phenomenon in detail and introduce why the use of Bigely tin plating brightener Sn-807 can effectively reduce the failure of white haze of tin plating layer.
With the development of technology, semi-bright nickel plating additives are gradually used in nickel plating processes in various fields, such as the surface nickel plating of electronic components, tube holders and substrates. The performance requirements for semi-bright nickel layers are getting higher and higher, including internal stress, ductility, uniformity, solderability and corrosion resistance.
In the nickel plating process, white spots on the plated layer is a relatively common problem, which not only affects the aesthetics of the plated layer, but also may reduce its corrosion resistance and overall quality. As a R&D and sales engineer for nickel plating brighteners, I will delve into the causes of this phenomenon and introduce why Bigely nickel plating brightener Ni-301 can solve this problem.
