What is ultrasonic tinning equipment?

Ultrasonic tin enamel equipment is an advanced metal surface treatment equipment. It uses ultrasonic waves to produce a cavitation effect in molten tin liquid, destroying and removing the oxide layer on the metal surface, so that the tin liquid can adhere to the metal surface more firmly and evenly. , forming a corrosion-resistant tin layer. This equipment does not require the use of flux, can improve the weldability and ductility of metal, and is suitable for the surface treatment needs of metal parts in electronics, electrical appliances, automobiles and other industries.
The composition of ultrasonic tin lining equipment
Ultrasonic tin lining equipment consists of tin pot, electric heating temperature control device and ultrasonic vibration system. A tin pot is a vessel that holds pieces of tin and heats them to melt them into liquid tin. The electric temperature control device is a device that controls the temperature of the tin pot to maintain the best state of the tin liquid. The ultrasonic vibration system is a system that generates and transmits ultrasonic waves and is used to achieve ultrasonic immersion soldering.
The ultrasonic vibration system includes an ultrasonic generator and an ultrasonic tool head. The ultrasonic generator can adjust the power and working mode of ultrasonic waves. The ultrasonic tool head is installed at the bottom of the tin pot and transmits ultrasonic waves into the tin liquid. After the tin liquid melts, turn on the ultrasonic wave, and a cavitation effect will occur in the tin liquid, which will eliminate the oxide layer on the metal surface, allowing the tin liquid to wet the metal surface and form a uniform tin layer on it. By immersing the metal in tin liquid, ultrasonic immersion tin soldering can be completed to achieve tin plating on the metal surface.

The exterior of the ultrasonic tinning equipment is wrapped in a stainless steel shell, which is anti-corrosion and high temperature resistant. It can also avoid the risk of metal dust coming into contact with the ultrasonic transducer, causing a short circuit or damaging the transducer.

Ultrasonic tin lining is based on the principle of cavitation
Ultrasonic dip welding is a special ultrasonic welding method that utilizes the cavitation effect of ultrasonic waves. The ultrasonic cavitation effect means that the tiny bubble nuclei in the liquid vibrate under the action of ultrasonic waves. When the sound pressure reaches a certain value, the bubbles will expand rapidly and then suddenly close. When the bubbles close, a shock wave will be generated. This expansion, closing, and oscillation and a series of dynamic processes. The cavitation effect can produce physical effects such as local high temperature and high pressure, shock waves, and micro jets, which can produce strong impact and peeling effects on liquid and solid surfaces.

Ultrasonic immersion soldering uses the shock waves and micro-jet generated by the ultrasonic cavitation effect in the tin liquid to destroy and remove the oxide layer on the metal surface, so that the tin liquid can wet the metal surface and form a uniform tin layer on the metal surface. . The advantage of ultrasonic immersion tin soldering is that it can be performed at room temperature, without the need to add flux or cleaning agents, saving energy and materials, reducing environmental pollution, and improving product quality and reliability.

No flux required
Ultrasonic tin plating and ultrasonic immersion tin soldering are flux-less welding processes that use ultrasonic energy to connect solder (such as tin) with materials such as copper, aluminum, and difficult-to-solder metals without the need for chemicals. This process can weld sensitive components that cannot be welded by traditional methods, and can also save costs, improve efficiency, and protect the environment.

Product advantages
Green and environmentally friendly: No need to use flux, no harmful gases or waste water, no pollution to the environment or harm to human health.

Achieve perfect welding: no tiny bubbles will be generated inside the solder, which will not cause welding quality problems such as cracks. There will be no defects in welded joints caused by corrosion of flux. It allows solder to penetrate into tiny gaps, making the welded joint strong and reliable.

Save production costs and improve production efficiency: You can use low-priced aluminum wires instead of expensive copper wires to save costs. No pretreatment or flux-related processes are required, simplifying the welding process and improving production efficiency.

Support the development of new materials and new products: It can successfully weld difficult-to-weld materials such as copper and aluminum, which is helpful for the development of new materials. It is suitable for solar cell glass, semiconductors, ceramic heaters and other products, and is helpful for the development of new products.
