The electronics manufacturing industry is an industry which cover a wide range of fields, encompassing the design, production, and assembly of electronic components, semiconductors, electronic devices, and electronic systems. This industry strives to produce a diverse range of electronic products such as computers, mobile phones, televisions, semiconductor chips, electronic components, communication devices and so on. Electronics manufacturing involves advanced process technologies, which aims at creating products with exceptional performance, superior quality, and high reliability to meet the ongoing demands of the global market. Also, it serves as a significant driver of technological innovation. Within electronics manufacturing, the application of nitrogen sealing technology is extensive, with some common applications outlined below:
Welding and Brazing
In the manufacturing and assembly of electronic components, welding and brazing are common processes. Using nitrogen for these processes reduces the presence of oxygen, prevents oxidation reactions, and enhances the quality and stability of connections. This is crucial for producing high-quality electronic components.
Vacuum Packaging
When manufacturing integrated circuits (IC) and other electronic components, they are typically encapsulated in a vacuum or controlled atmosphere. Nitrogen can be used to create a high-purity atmosphere. This ensures no impurities enter during the packaging process, therefore maintaining the components' performance and reliability.
Silicon Wafer Manufacturing
In the semiconductor industry, the manufacture of silicon wafers is critical. Nitrogen is utilized for annealing and other process steps to improve wafer quality, reduce flaws and enhance the performance of electronic devices.
Electronic Device Assembly
During the assembly and testing of electronic equipment, nitrogen can be employed to create a sterile environment, preventing contamination from dust, impurities, and microorganisms. This is vital for manufacturing high-demand electronic devices.
Electronic Components Packaging
In the packaging process of electronic components, nitrogen is typically used to fill the atmosphere within the packaging material, which can reduce the presence of oxygen, prevent product oxidation, maintain product performance and extend its lifespan.
In the field of electronics manufacturing, it is crucial to strictly control the purity and usage of nitrogen during the nitrogen sealing process. Typically, the nitrogen used requires an extremely high purity level, exceeding 99.999%. The usage of nitrogen needs to be adjusted based on specific application scenarios and process requirements. The primary objective is to maintain a low-oxygen environment to prevent oxidation reactions. Therefore, it’s necessary to appropriately set the nitrogen usage according to the specific needs of each stage and different equipment on the production line, which to ensure the high-quality production of electronic components.
