Bigely trivalent chromium galvanized black passivation solution BZ-216 is a black passivate designed for pickled zinc deposits in the galvanizing process. It produces a dense, homogeneous and highly corrosion resistant black passivate film on the galvanized surface, which enhances the decorative and protective properties of the coating.
In the electronic soldering industry of integrated circuits, a layer of solderable tin plating is usually plated on the component pins to improve the soldering performance of electronic devices, and the current application of solderable tin plating layer is necessary and irreplaceable. However, in practice, the solderability of the plating is prone to failure.
Some customers inquire that the brightness of the plated layer of Bigely Sn-807 tin plating brightener is really that good, this article will introduce it.
In the chromium plating process, the size of the current is one of the most important parameters in determining the quality of the plated layer. The size of the current affects the deposition rate, deposition uniformity, gloss, hardness and adhesion of the coating in many ways.
Localized blistering of the plating is a common quality problem in the production of barrel nickel plating of iron parts, and the following are some of the common causes that may lead to such failures:
The use of Cu-510, a dye-based acid copper brightener, is not only widespread but also of particular importance in the electroplating process. Cu-510 is an important additive to improve the quality of copper sulfate plating. In the following, we will introduce the mechanism of action of Bigely Cu-510 dye-based acid copper brightener and its advantages in electroplating production.
