Ultrasonic Tinning Machine (Immersion Welding Equipment)
The ultrasonic tinning machine (immersion type) provides an environmentally friendly soldering solution that does not use flux, and fundamentally avoids various problems of conventional flux soldering, thereby providing stable and reliable soldering.
Introduce :
When a large area of coating is required, immersion welding is undoubtedly an ideal choice. On the one hand, ultrasonic immersion welding equipment transfers heat into the solder tank through the working head of the heating device, causing the solder to melt and form a liquid state. On the other hand, the high-frequency vibration energy of ultrasound enters the liquid solder, which will cause cavitation on the surface of the welded part to be welded, directly causing the oxide film on its surface to fall off, providing a perfect surface for welding and achieving the goal of welding without using flux.
Principle :
Ultrasonic immersion welding is a process that utilizes the cavitation effect generated by ultrasonic waves in molten tin solution to strip and remove the oxide layer on the surface of the metal immersed in the tin solution, which is then carried away by the sound wave flow, making the tin solution adhere more firmly and uniformly to the clean metal surface.
Advantage :
1. Green and environmentally friendly soldering (indium) solution
a. It will not emit any harmful chemicals to the environment and human health, and does not require soldering flux or soldering flux cleaning process.
b. When soldering (indium), no flux is used, no harmful gases are emitted, no industrial wastewater is generated, and there is no water pollution or air pollution.
2. Achieve perfect soldering (indium)
a. When soldering (indium), if flux is used, tiny bubbles will be generated inside the solder (indium), which can lead to quality problems such as cracks over time. However, ultrasonic soldering (indium) does not use flux for soldering, and the vibration energy allows the solder to penetrate very small gaps without generating tiny bubbles inside the solder (indium), thus achieving perfect soldering (sealing).
b. Helpless soldering flux welding will not cause defects in the welded joint due to strong corrosion of the flux.
C. By using ultrasonic vibration to allow solder to penetrate into small gaps, the welded joint is firm and reliable.
3. Save production costs and improve production efficiency
a. Using aluminum wire instead of expensive copper wire can greatly save costs (saving 80%).
b. Due to the absence of soldering flux, there is no need for pre-treatment or flux related processes, which can save equipment and production costs, simplify soldering processes, and improve production efficiency.
4. Support the development of new materials and products
a. Successfully welding materials such as glass, ceramics, aluminum, and non-metallic materials that are difficult to weld using traditional welding methods can contribute to the development of new materials.
b. Suitable for solar cell glass, semiconductor, and ceramic heaters, easy to weld for dual materials (aluminum copper, copper glass, aluminum glass, aluminum ceramic), and helpful for the development of new products.
Precautions :
The surface cleanliness of welded parts has a significant impact on welding performance. It is recommended to clean the welding surface with acetone before welding to achieve better welding results.
