What is an Ultrasonic Tinning Machine

1. Basic Principles of Ultrasonic Tinning

Ultrasonic tinning machines practice ultrasonic waves to molten tin, producing high-frequency vibrations exceeding 20,000 instances per 2dand inducing a cavitation effect. Once the metallic workpiece to be tinned or soldered is immersed in the molten tin, the oxide layer on the workpiece's floor is stripped away, and air in the interstitial areas is released, permitting the molten tin to adhere greater evenly and firmly to the workpiece's surface.

The tinning technique eliminates the want for flux, enhancing the metal's solderability and ductility.Tinned workpieces only need to be immersed directly in the tin bath for 3-10 seconds.

This process is commonly used for surface treatment and soldering of metal parts in the electronics, electrical, automotive, and new energy industries, such as tinning or soldering silver, copper, nickel, and aluminum wiring harnesses, tabs, and sheet materials.

2. Ultrasonic Tinning Machine Structure

The ultrasonic tinning machine primarily consists of the main unit (ultrasonic vibration system, tin bath, electric heating temperature control device), ultrasonic generator, foot switch, and other components. It is connected to a 220V 50Hz household power supply.

3. Application Features

Many metal materials undergoing tinning often develop an oxide film on their surfaces during storage, particularly on aluminum. This film significantly interferes with soldering or tinning. Traditional tinning processes require pre-treatment to remove the oxide layer and use flux, increasing processing costs and compromising quality assurance. FUNSONIC has integrated ultrasonic expertise with advanced technology to develop its own ultrasonic tinning machine.

Advantages of Ultrasonic Tinning Machines

Environmentally friendly soldering solution: Soldering without flux effectively avoids the generation of harmful gases. Eliminates the need for pre-cleaning the material surface, eliminating the need for post-process wastewater disposal.

Achieving perfect soldering: Using flux during soldering can create tiny pores within the solder. If the process isn't strictly controlled, this can lead to cracking, peeling, cold joints, and burnout during use. However, ultrasonic tinning eliminates flux. The vibration power lets in the solder to penetrate even the smallest gaps, casting off tiny bubbles and pores inside the solder and reachinga strong bond between the solder and the cloth being soldered. Avoids the corrosive consequences of a number fluxes, which can have an effect on weld nice and minimize provider life. 

Reduce manufacturing prices and enhance efficiency: Overcome the present day concern of welding aluminum. Replacing luxurious copper with aluminum can appreciably minimize fabric costs. By getting rid of the want for flux, the soldering manner is simplified, enhancing manufacturing effectivity and labor costs.

Supporting the Development of New Materials and Products: Successfully welds difficult-to-weld substances such as glass, ceramics, and aluminum, contributing to the improvement of new materials. Suitable for photo voltaic mobile glass, semiconductors, and ceramic heaters, it helps composite welding of twin substances(aluminum-copper, copper-glass, aluminum-glass, and aluminum-ceramic), facilitating new product development.
