Electronics Industry(Semiconductor and Chip Manufacturing)
In the manufacturing process of semiconductors and chips, the requirements for the production environment are extremely strict. The high temperature of 400℃ can meet the needs of some special processes, such as heat treatment and reflow soldering of chips. The inert atmosphere formed by filling with nitrogen can effectively prevent electronic components from oxidation, corrosion or moisture at high temperatures, and avoid the impact of impurities on chip performance. For example, in the chip packaging process, high temperature can make the packaging material better combined with the chip, and nitrogen protection can ensure that the electrical performance of the chip is not damaged, improving the reliability and stability of the product.
PCB board manufacturing
During the manufacturing process of PCB boards, welding and baking processes are required. The high temperature of 400℃ can accelerate the melting and flow of solder during welding and improve the welding quality. The nitrogen environment can prevent the oxidation of copper lines and ensure the conductivity of the circuit board. Moreover, in the manufacturing of some high-density and high-precision PCB boards, the control requirements for temperature and atmosphere are higher, and the 400℃ nitrogen oven can just meet these needs.
New Energy Battery Industry
Electrode Material Processing
During the preparation process of the electrode materials of new energy batteries, high-temperature treatment is required to improve their crystal structure and electrochemical properties. The temperature of 400℃ can promote the crystallization and reaction of electrode materials, improve the charging and discharging performance and cycle life of batteries. Nitrogen protection can prevent electrode materials from being oxidized at high temperatures, ensuring the purity and performance stability of materials. For example, the electrochemical performance of the positive electrode material of lithium-ion batteries will be significantly improved after being treated in a high-temperature nitrogen environment.
Drying after battery assembly
After the battery is assembled, it needs to be dried to remove the internal moisture to prevent moisture from affecting the performance and safety of the battery. The high temperature of 400℃ can quickly evaporate moisture and improve the drying efficiency. At the same time, the nitrogen environment can prevent the oxidation of metal parts inside the battery and extend the service life of the battery.
Photovoltaic module industry
Sintering of photovoltaic cells
During the production process, photovoltaic cells need to undergo a sintering process to improve the photoelectric conversion efficiency of the battery. The temperature of 400℃ can make the electrode materials such as silver paste on the surface of the cell better bonded with the silicon wafer, reduce the contact resistance, and increase the output power of the battery. Nitrogen protection can prevent the cell from being oxidized at high temperatures, ensuring the performance and stability of the cell1.
Pre-packaging drying of photovoltaic modules
Before packaging, photovoltaic modules need to ensure internal drying to prevent water vapor from damaging the modules. High-temperature drying at 400°C can quickly remove moisture from the module, and the nitrogen environment can prevent oxidation and aging of the materials inside the module, thereby improving the service life and power generation efficiency of photovoltaic modules.
Medical equipment industry
High-temperature sterilization and drying
For some high-temperature resistant medical equipment, such as metal surgical instruments, glassware, etc., a high temperature of 400°C can be effectively sterilized. At the same time, the nitrogen environment can prevent the equipment from rusting and oxidation at high temperatures, ensuring the quality and service life of the equipment. Moreover, in the production process of some medical consumables, such as the molding and drying of polymer materials, a 400°C nitrogen oven can also provide suitable process conditions.
