Automotive electronic plasma surface treatment technology is not only a "pretreatment process", but also closely related to the subsequent process。
The automotive electronics industry has higher and higher requirements for process safety, reliability and stability, and new processes and new materials are constantly emerging, so the dispensing, coating, welding and other processes in the production process will become more and more complex.
Due to the presence of organic dirt and metal oxides on the surface of the product, it will lead to various problems such as insufficient adhesion between the medium, unreliable conductivity, insufficient glue flow, difficult coating, insufficient welding strength, etc., and plasma surface treatment is often used to solve the above process pain points.
Process characteristics
The application principle of plasma surface treatment involves ionizing oxygen or hydrogen gas using radio frequency power to form oxygen ions and hydrogen ions. These ions then chemically react with organic contaminants or metal oxides on the product surface, forming gaseous carbon dioxide and water, thereby removing contaminants and activating the product surface. Plasma surface treatment is typically used to remove organic contaminants from non-metal product surfaces, metal oxides from metal surfaces, and to activate product surfaces. The application of plasma technology demands high standards.
Key points of plasma surface treatment process include:
1. Multiple chemical processes effectively remove organic contaminants and metal oxides from product surfaces, activating the product surface (e.g., WCA<10° for optical glass/lenses, WCA<20° for LEDs/PCB substrates).
2. 100% safe for products, without ion bombardment, low temperature, low pressure, ESD-free, no arc, no splashing, no water ripples, no UV damage.
3. Batch processing in-line ensures production efficiency, can be processed in atmospheric conditions, and is easy to maintain.
4. No dust particle contamination on product surfaces.
5. Do not cause damage or roughness changes to sensitive product surfaces.
6. Different platforms can be chosen for different product applications to ensure high efficiency and flexibility.
7. Compatible with production of different sizes of products and rapid switching to ensure compatibility.
Plasma surface treatment technology is applied in industries such as semiconductors, automotive electronics, consumer electronics, and LED manufacturing. Innovative plasma technology offers significant opportunities to replace traditional plasma technologies. Equipment capacity and stability are crucial for production enterprises. With years of experience in these industries, Axxon has developed mature and stable high-speed, high-precision motion platforms, which can be flexibly matched with different platforms and plasma heads, and equipped
