Ultra thin nickel plated iron foilIt is a high-performance thin film material that has the advantages of good electrical insulation, heat resistance, corrosion resistance, and arc resistance. Therefore, it is widely used in the packaging of electronic devices, chip packaging, and sensor manufacturing. The production process of ultra-thin nickel plated iron foil is to first treat the iron foil, then cover it with a film by nickel plating, and finally perform heat treatment to form the final ultra-thin nickel plated iron foil. Ultra thin nickel plated iron foil has excellent thermal stability, which can effectively resist the effects of high and low temperatures, suppress the deformation and damage of electronic components, and thus improve the reliability of electronic components.
Nickel plating is mainly for wear resistance, corrosion prevention, and rust prevention. It is generally thin in thickness and can be divided into electroplating and chemical processes.
Nickel has good chemical stability in the atmosphere and alkaline solution, is not easily discolored, and is only oxidized at temperatures above 600 ° C. It dissolves slowly in sulfuric acid and hydrochloric acid, but is easily soluble in dilute nitric acid. It is easily passivated in concentrated nitric acid and therefore has good corrosion resistance.
Nickel plating has high hardness, is easy to polish, has high light reflectivity, and can increase aesthetics. Its disadvantage is that it has porosity. To overcome this disadvantage, multi-layer metal coatings can be used, with nickel as the intermediate layer.
Nickel is a cathodic coating on iron and an anodic coating on copper
Application:
It is usually used to protect decorative coatings in order to prevent corrosion and increase aesthetic appeal. Nickel plating on copper products is ideal for corrosion prevention
However, due to the high value of nickel, copper tin alloy is often used instead of nickel plating.
In addition,
Ultra thin nickel plated iron foilIt also has good corrosion resistance, which can effectively prevent corrosion of metal surfaces and significantly improve the service life of electronic components.
In short, ultra-thin nickel plated iron foil is a high-performance thin film material that can effectively resist external electromagnetic waves and interference, thereby protecting internal electronic components from external interference. Its application can significantly improve the reliability and stability of electronic components, making it a very practical technology. Therefore, ultra-thin nickel plated iron foil technology is expected to have greater development and application in the future.
