Screen Printing Equipment Application in New Energy Automobile Industry

With the vigorous development of the new energy automobile industry, screen printing equipment is increasingly used in this field. New energy vehicles not only require efficient batteries and advanced drive systems, but also require precise and stable printing on various components to meet the requirements for electrical connection, sealing protection and aesthetics. This article will explore the application and importance of screen printing equipment in the new energy automobile industry.

One of the core components of new energy vehicles is the SiC power module, which is widely used in electric drive electronic control systems to increase cruising range and achieve lightweight and efficient power electronic drive systems. In the production and preparation process of SiC power modules, high-precision screen printing technology is required for metallization, wafer glass slurry coating and packaging. Especially for the coating of wafer glass slurry, screen printing technology can ensure that after wafer cutting, a sealed glass protective layer can be formed around the chip, thereby improving the reliability and stability of the module.

In addition to SiC power modules, new energy vehicles also use a large number of ceramic sensors, such as air conditioning pressure and temperature composite sensors, vacuum pressure sensors, etc., for pressure measurement and monitoring of refrigerant, oil, air conditioning, and brakes. In the preparation process of ceramic sensors, the printing of electrode layers, resistive layers and insulating protective layers all rely on screen printing technology. Due to the need for repeated printing, the registration accuracy of printing is extremely high. Therefore, it is necessary to use CCD automatic registration printing equipment to ensure high-precision printing effects.
In addition, AMB ceramic copper clad laminate is the best packaging material for SiC chips, and its screen printing process is equally important. During the printing process, active solder is used to form a soldering layer so that the copper foil layer can be firmly soldered to both sides of the ceramic substrate. If the printed film thickness is uneven, vacuum sintering conditions cannot be achieved after welding, which will seriously affect the reliability of the ceramic copper-clad laminate. Therefore, it is crucial to use high-precision screen printing equipment to ensure printing accuracy and stability.

Screen printing equipment also plays an important role in the appearance and interior of new energy vehicles. In the automobile manufacturing industry, the latest screen printing technology is used for marking automobile exterior parts and printing decorative parts, etc., improving the aesthetics and personalization of automobiles. For example, in the printing process of new energy vehicle body logos and interior decoration parts, the use of high-definition and high-efficiency screen printing technology can ensure the quality and production efficiency of the printed matter.
With the continuous expansion of the new energy vehicle market and the development of technology, the requirements for screen printing equipment are becoming higher and higher. On the one hand, the printing accuracy and stability of the equipment need to be improved to meet the high printing quality requirements of core components of new energy vehicles; on the other hand, the production efficiency and intelligence level of the equipment need to be improved to adapt to the rapid development of the new energy vehicle industry. needs.
When selecting screen printing equipment, companies should consider factors such as the printing accuracy, stability, production efficiency, and intelligence level of the equipment. For example, choosing a high-precision screen printing machine equipped with a CCD alignment vision system can achieve high-precision printing effects; choosing an intelligent screen printing machine with functions such as remote data debugging and intelligent 'cloud' online management of production data can achieve Improve production efficiency and intelligence level.
In short, screen printing equipment plays an irreplaceable role in the new energy automobile industry. With the continuous development of the new energy automobile industry, the application prospects of screen printing equipment will be broader. Enterprises should increase investment in research and development of screen printing technology, continuously improve the printing accuracy, stability and intelligence level of equipment, and make greater contributions to promoting the sustainable development of the new energy automobile industry.
