Currently used to connect to ceramic and metal mechanical connection methods mainly include bolted and heat, but the two methods have significant limitations. Compared with the above two methods, the junction of welding high strength, high temperature resistant, and can guarantee a certain air tightness, and the geometric shape and size fittings requirement is not high, a wider range of application. Therefore, a metal ceramic welding method has become the focus of the study hotspot.
Ultrasonic soldering iron first by heating up and under the influence of ultrasonic wave to achieve low temperature melting welding layer to form a liquid state, ultrasonic wave propagation in the liquid, the ultrasonic field produce cavitation effect, mechanical effect and thermal effect, promote chemical reaction usually difficult to achieve, summed up by ultrasonic wave function and mutual influence of middle layer to improve the wettability on the surface of the metal in the ceramic, at the same time, the tremendous power of ultrasonic wave to eliminate the residual stress of welded joint.
Ultrasonic soldering iron is considered to be more environmentally friendly compared to traditional electric iron welding equipment in terms of equipment. Ultrasonic soldering iron device generates a lot of heat during welding and ultrasonic unique combination of high-frequency oscillations, it can be treated to eliminate the influence of the welding surface of the oxide film, and completely eliminate the air bubbles generated during the welding of the traditional.

]]>And with a light blue metal indium is silvery white, quality of a material is very soft, can use nail notch. Indium plasticity, ductility, can be pressed. Metal indium is mainly used in the manufacture of low metal, bearing metal, semiconductor, electric light source such as raw materials.
Ultrasonic soldering iron welding is a new type connection under the action of heat and ultrasonic methods, can be realized in the atmosphere and lower temperature of glass and metal connected directly, without intermediate transition layer material, welding temperature is lower than the softening point, the welding deformation is small, high precision, good sealing, etc. Suitable for electronics, electrical appliances and micro mechanical product assembly and connection, such as electric vacuum device, electronic sensor, fuel cells, etc., in the field of glass, or ceramic and metal even has a broad application and development prospect.
CHEERSONIC developed ultrasonic soldering iron equipment, because of its low temperature welding, high strength combined point advantage in the field of lead-free soldering play a huge advantage.

]]>Tin is a malleable, ductile and highly crystalline silvery-white metal. When a bar of tin is bent, a crackling sound known as the tin cry can be heard due to the twinning of the crystals.In modern times, tin is used in many alloys, most notably tin/lead soft solders, which are typically 60% or more tin. Another large application for tin is corrosion-resistant tin plating of steel.
Ultrasonic soldering machine is a new ultrasonic bonding tool, ultrasonic vibration by soldering the solder surface of the article and firmly bonded, is widely used in glass, ceramics, crystal silicon devices (the LED, LCD, etc.), the accuracy of the welding of a superconducting material, packaging, and other electronic products between weld metal and nonmetal. No need to use when using flux (ultrasonic vibration of the tool head and the surface to remove any dirt or oxide layer), comprising: a high stability back to temperature quickly, without flux, does not produce harmful gases, effectively prevent the generation of bubbles and pinholes etc., to improve production efficiency, product quality and reliability.
CHEERSONIC developed ultrasonic soldering machine Features: ultrasonic removal of solder and the solder surface oil and base metal oxide to protect the metal surface to achieve the perfect cleanliness; increase the welding area, reducing the surface tension of the material to be welded; without any flux, does not appear harmful gases, welding protection of personal health workers; post-weld-free cleaning, eliminating the use of flux after soldering, electrical insulation performance degradation and short-circuit problems: internal pads without bubbles and pinholes generation, removal weld, false welding, improve the welding quality, guarantee yields and reduce welding time, improve work efficiency; pads smooth appearance, high joint strength, not aging, no external pressure stress, to prevent oxidation of the surface once again occurred during welding.

]]>PCB, also known as printed circuit board, is an important electronic components, electronic components to support the body, is the carrier of electronic electrical connection. Since it is made of electronic printing, therefore is called "printed circuit board.
Ultrasonic soldering systems offer the advantage of the fluxless soldering of many metals in common use as well as previously difficult to solder materials such as aluminium, ceramics, glass and silicon’s used in microelectronic applications. The unit consists of the soldering iron itself, which is rated at 80W and can reach temperatures of up to 450°C, and is fitted with interchangeable screw in copper bits. The ultrasonic transducer is built into the soldering iron handle and the need to prevent this unit being overheated necessitates the continuous use of a cooling air supply.
Ultrasonic soldering iron is an intermediate layer to melt by the heat of welding materials, and polyethylene solution through ultrasonic cavitation bubbles generated in the liquid, forming a void-free seamless or welded. Ultrasonic welding does not require high temperature electric iron can be based on ultrasonic welding at a low temperature, low temperature welding stress relaxation in favor of leaving the stress decreases, to avoid weld cracking phenomenon.
