Ultrasonic applicable industries

Medical industry: cleaning, disinfection, sterilization of medical equipment, cleaning of laboratory utensils, etc.

Semiconductor industry: high cleanliness cleaning of semiconductor wafers.

Optical industry: degreasing and sweat removal of optical devices.

Petroleum industry: cleaning and dredging of metal filters, cleaning of containers and exchangers, etc.

Electronics industry: The electronics industry is the earliest and most popular industry for cleaning applications.

Electronic parts such as semiconductor tube housing, IC housing, crystal housing, relay housing, electronic tube housing, etc.; electronic components such as IC chips, resistors, crystals, semiconductors, original film circuits, etc. The base of electronic components is made of semiconductor material and encapsulated in a metal or plastic housing. Before packaging, not only the housing must be cleaned, but also the base must be cleaned.

The flux used for PCB component welding is divided into three types: water-soluble, rosin and no-clean. The first two are the most used ones. Most use ultrasonic cleaning (and many of them use alcohol scrubbing). In principle, the no-clean type should No cleaning, but most manufacturers still need cleaning even if they use no-clean flux soldering components. In particular, high-density PCB and high-density IC pins are not cleaned, which will inevitably cause dust to be adsorbed between high-density circuits and IC pins. Once the environmental humidity is high, short circuits between high-density wires and pins are prone to failures. , And once the environment is dry, the short-circuit fault disappears by itself, and this type of fault is not easy to find. Therefore, electronic complete machine factories all over the world insist on cleaning PCB boards.

In the production of connectors, connectors, adapters and other devices, they must also be cleaned before electroplating and assembly, otherwise the dust and oil adsorbed on these assembled parts will inevitably affect their conductivity and insulation performance, especially some complex multi-core This is especially true for connectors.

Cleaning of electronic materials after processing and molding: Electronic materials such as wafers, silicon wafers, and piezoelectric ceramics are products supplied to component manufacturers, and their products must be cleaned before they leave the factory.

Electromechanical industry: In the electromechanical industry, from mechanical parts to mechanical parts, from electrical parts to electrical parts, there are cleaning requirements, such as gears, crankshafts and even gearboxes, as well as mechanical and electrical components on electrical parts, as well as some precision Mechanical parts and electrical parts need to be cleaned. Most companies use traditional cleaning methods, such as immersion cleaning and spray cleaning. This cleaning method is not only labor intensive, but also easy to cause environmental pollution and waste of water resources. Some companies use ultrasonic cleaning in technological transformation to eliminate the drawbacks of traditional cleaning, especially some mechanical parts with complex shapes.

Pharmaceutical industry: Ultrasonic cleaning technology has been used by many pharmaceutical companies, especially for the cleaning of vials, oral liquid bottles, ampoules, and large infusion bottles, as well as the cleaning of butyl rubber stoppers and natural rubber stoppers. For bottle cleaning, ultrasonic cleaning technology is used to replace the original brush machine, which is achieved through the processes of inverting water injection, ultrasonic cleaning, internal and external flushing, air drying, and overturning.

Light and textile industry: light industry, such as compressors in air conditioners, refrigerators, refrigerators; watch parts, watch components, etc.; textile industry, such as precision textile equipment, spinnerets, etc.; jewelry industry, such as gold and silver jewelry, jewelry, jade, etc. , All need to be cleaned. Some parts, components and components, such as compressors, spinnerets, etc., have complicated shapes, or blind holes or micro holes, which can only be cleaned by ultrasonic. Some large-scale production plants even use ultrasonic chain or lift-type complete sets. equipment.

Surface treatment industry: Surface treatment is an integral part of the light industry, including mechanical parts electroplating, metal and non-metal cabinet coating, optical glass or lens coating, etc. The use of ultrasonic cleaning technology for cleaning before and after electroplating or coating has become one of the This new typical process, especially some multi-core sockets in electronic products, must be electroplated due to quality requirements. After electroplating, the quality requires that the multi-cores must be insulated. Often, the multi-cores are not insulated after electroplating, and acetone is used. After immersion and cleaning with alcohol and other methods, the resistance value is infinite, but it does not meet the quality requirements. Ultrasonic cleaning is used and after drying, it fully meets the quality requirements. Direct introduction of ultrasonic waves into electroplating can also improve the uniformity of the plating solution and the density of the plating layer.

Railway depot repair field: The "Three-machine Maintenance Regulations" of the Ministry of Railways of China and some depot repair technical regulations of the railway system all involve cleaning. Ultrasonic cleaning is more common in railway systems, but it is a brand-new topic for the non-dismantling and imperial cleaning of large equipment such as train air conditioning units, diesel engine units, and locomotive radiators. It is the first case in China to use ultrasonic cleaning equipment to clean train air conditioners without dismantling the depot of passenger cars. The reduction of labor intensity, the improvement of cleaning quality, the reduction of environmental protection costs, the improvement of civilized production, and the improvement of on-site management have all created a new situation, but the level of popularization is very low.

Process application before electroplating and spraying: product spraying pretreatment process, the general traditional process uses acid to treat the workpiece, which causes serious environmental pollution and poor working environment. At the same time, the residual acid after pickling and rust removal of complex parts is difficult Rinse well. After the workpiece is sprayed, the time is not long, and rust appears along the gap, which damages the surface of the coating, and seriously affects the appearance and internal quality of the product. After the ultrasonic cleaning technology is applied to the pre-treatment of coating, not only can the dirt on the surface of the object and the gap be quickly peeled off, but also the sprayed layer of the painted part is firm and will not return rust.

Using the cavitation effect produced by ultrasonic waves in the liquid, the oil stains on the surface of the workpiece can be cleaned, and with an appropriate cleaning agent, the surface of the workpiece can be quickly treated with high cleanliness.

The electroplating process has high requirements for the surface cleanliness of the workpiece, and the ultrasonic cleaning technology is an ideal technology that can meet this requirement. Ultrasonic cleaning technology can replace solvents to clean oil stains; it can replace electrolytic oil; it can replace strong acid etching to remove rust and scale on the surface of carbon steel and low-alloy steel.

Others: liquid defoaming (removing dissolved air) in photosensitive material manufacturing, papermaking, and certain food fields.
