Brief introduction of ultrasonic soldering iron
Introduction of electric soldering iron
Electric soldering iron is the most commonly used soldering tool. The main purpose is welding machine components and wires. According to the structure, it can be divided into internal heating electric soldering iron and external heating electric soldering iron. According to the function, it can be divided into soldering electric soldering iron and tin suction electric soldering iron. It has the advantages of small size, convenient operation and easy maintenance. However, the soldering tip will generate high temperature during use, which is dangerous, so pay attention to safety during use. The use of flux can help to remove oxides on the metal surface, which is good for soldering and protects the tip of the soldering iron. (Solder: Solder wire with rosin core is generally used for soldering electronic components. This kind of solder wire has a low melting point and contains rosin flux, which is very convenient to use. Flux: The commonly used flux is rosin or rosin. Rosin is dissolved in alcohol).
The external heating electric soldering iron is composed of a soldering iron tip, a soldering iron core, a shell, a wooden handle, a power lead, a plug and other parts. Since the soldering iron tip is installed inside the soldering iron core, it is called an externally heated electric soldering iron.
The internally heated electric soldering iron consists of a handle, a connecting rod, a spring clip, a soldering iron core, and a soldering iron tip. Because the soldering iron core is installed inside the soldering iron tip, it generates heat quickly and has a high heat utilization rate. Therefore, it is called an internally heated electric soldering iron.
Principle of Ultrasonic Soldering Iron
Ultrasonic electric soldering iron is a combination of electronic technology and ultrasonic principles, and ultrasonic is added on the basis of ordinary soldering iron. It is a welding tool that can improve the welding quality of some special materials.
Flange, also called flange flange or flange. Flanges are parts that connect pipes to each other and are used for connection between pipe ends; flanges are also used at the inlet and outlet of equipment to connect between two equipment.
Operation process
Advantages of ultrasonic soldering iron
1. Remove false welding
2. The solder joints in the welding area are smooth and beautiful, and there are no bubbles or false soldering inside the solder joints, which prevents oxidation.
3. Perfect welding of the object to be welded, high solder joint strength, not easy to age, no internal and external pressure stress
4. High success rate of one-time welding
It has the advantages of high stability, fast temperature recovery, no need for flux, no harmful gas, and effective prevention of bubbles and pinholes, thereby improving production efficiency, product quality and reliability.
Ultrasonic soldering iron application
Ultrasonic soldering irons can be used in special industries, such as the welding of solar cell bus bars, high-precision welding of superconducting materials, ceramic parts, and other places where traditional soldering irons cannot be operated.
1. The bus bar welding of thin-film solar cells and silicon body solar cells.
2. Product packaging of high-precision sensor (laser, image, sonar, infrared heat exchanger), triode, amplifier and other electronic control components.
3. High-precision welding of superconducting materials.
4. Glass, ceramics, silicon crystal devices (LED, liquid crystal display, picture tube, chip, etc.) where ordinary electric soldering iron cannot be soldered.
5. Admission test of mass-produced instruments and equipment, scientific experiments, etc.
