Everyone know that iron can not get wet,it is easy to rust. According to the facts, it is. Most of the corrosion of metal materials occurs in the atmospheric environment, the atmosphere contains oxygen, humidity, temperature changes and pollutants and other corrosion components and corrosion factors.
Salt fog corrosion is one of the most common and destructive atmospheric corrosion. Salt spray test is an accelerated corrosion resistance evaluation method for artificial atmosphere. The corrosion resistance of the products was tested after the surface treatment of various materials, including conformal coating, electroplating, inorganic and organic coating, anodizing anti-rust oil and so on. All widely used in the making of PCBA.
