40k ultrasonic soldering iron equipment

Product Description

Ultrasonic soldering iron is also called ultrasonic tin coating machine and ultrasonic soldering machine. It can use the cavitation of ultrasonic waves to braze metal and non-metallic materials without flux. The biggest difference with ordinary soldering iron is that for materials that are difficult to obtain tin, ultrasonic soldering iron can directly braze materials such as glass, ceramics, titanium alloys, stainless steel, molybdenum alloys, etc. without the need to metallize glass ceramics.

Device Overview

An ultrasonic soldering iron, also known as an ultrasonic tin applicator or ultrasonic soldering machine, utilizes the cavitation effect of ultrasound to bond metals and non-metals without the need for flux. The key distinction from conventional soldering irons lies in its capability to directly solder materials that are difficult to tin, such as glass, ceramics, titanium alloys, stainless steel, and molybdenum alloys, without requiring metallization of the materials—a feature that significantly simplifies the process and reduces costs. Ultrasonic soldering equipment is considered a more environmentally friendly welding solution. Compared to traditional soldering irons, it generates substantial heat during operation; combined with the high-frequency oscillations of ultrasound, this approach minimizes interference from oxide films on the workpiece surface and eliminates the bubble formation issues associated with conventional welding methods.

Operational principle

During ultrasonic tin welding, heat from a separate energy source melts the solder before applying vibrational energy. The molten solder then serves as the acoustic transmission medium for ultrasonic vibrations. When high-frequency vibration energy is applied to the molten solder, controlled acoustic cavitation occurs at the tip of the welding tool, breaking down and dispersing surface oxides. The collapse of these microcavities cleans all surfaces, allowing the liquid solder to wet and bond pure metals.

How to Select a Model?

Differences from 60k ultrasonic soldering irons:

1. Amplitude and power: According to ultrasonic principles, higher frequencies correspond to smaller amplitudes. The 40k ultrasonic soldering iron exhibits greater amplitude than the 60k model. Typically, the power output of a 40k ultrasonic soldering iron ranges from 9–30 W, whereas that of a 60k model is generally 5–15 W, indicating a relatively higher power level for the 40k model.

2. Welding performance: The 60 kHz ultrasonic soldering iron operates at a higher frequency, delivering more concentrated energy and superior welding precision, making it suitable for delicate components. The 40 kHz soldering iron features greater amplitude and power, generating relatively more heat during welding; it may yield better results when working with thicker materials or those with excellent thermal conductivity.

3. Application scenarios: The 40 kHz ultrasonic soldering iron is commonly used in pre-treatment processes for silicon wafers or the semiconductor industry, and is also suitable for welding thin aluminum products as well as small, thin aluminum-magnesium alloy materials. The 60 kHz model is primarily employed in post-processing stages for semiconductor materials or extremely thin magnesium alloys, making it particularly suitable for welding micro components that require exceptional precision.

4. Mold dimensions: The mold size of ultrasonic soldering irons is typically inversely proportional to the frequency; a 40 kHz model requires a larger mold than a 60 kHz one.
