Corrosion, characterized by the deterioration of materials or their properties due to environmental factors, is predominantly influenced by atmospheric conditions. The atmosphere contains corrosive elements such as oxygen, humidity, temperature fluctuations, and pollutants, making it conducive to corrosion.

One widely adopted method for testing corrosion resistance is the salt spray corrosion test, which simulates chloride-rich environments akin to those found in oceanic and saline-alkali regions. This testing method aims to evaluate a product's ability to withstand corrosion under adverse conditions encountered during normal usage.

The salt spray test is categorized into two types: natural environment exposure and accelerated simulated salt spray environment testing. The latter employs specialized chambers to create accelerated corrosion conditions, significantly expediting the corrosion process compared to natural exposure tests.

Salt fog simulation tests include neutral salt fog test (NSS), acetate fog test, accelerated acetate fog test (CASS), and variable salt fog test. Other problemsEach test method offers unique advantages and is tailored to specific corrosion assessment needs.

Our salt spray testing adheres to the GJB548B standard, method 1009, ensuring accuracy and reliability. By subjecting products to controlled salt spray environments, we assess their resistance to corrosion, a critical aspect of product durability and reliability.

In conclusion, as the demand for integrated circuit metal packages grows, comprehensive environmental adaptability assessments, including salt spray corrosion testing, become essential. Addressing corrosion challenges through innovative techniques like heat treatment, high-temperature sealing processes, and electroplating is crucial to enhancing the corrosion resistance of metal packaging and meeting customer requirements for reliable products.
