Shandong ultrasonic cleaning machine for circuit board parts cleaning

Washing is a labor closely related to people's practical life, and humans have been engaged in this labor since ancient times. Due to the simplicity of traditional cleaning operations or simply being a process attached to the production process, it has not received widespread attention. Entering the 21st century, people's lives have shifted from the stage of basic needs to the era of comfort. The increasing demand for cleaning products has accelerated the pace of new product development; At the same time, the rapid development of the manufacturing industry has also promoted the rapid progress of enterprises such as cleaning equipment and cleaning agents. The huge market demand in both civilian and industrial cleaning fields has created a new future for China's cleaning industry.
Scope of Application
The cleaning involved in the industrial production labor process belongs to the category of industrial cleaning. Food industry. Textile industry. Paper industry. Printing industry. Petroleum processing industry. Transportation industry, power industry, metal processing industry, machinery industry, automobile manufacturing, instrumentation, electronics industry, postal and telecommunications, household appliances, medical instruments. Optical products, military equipment, aerospace, atomic energy industry, etc. are widely used in cleaning technology.

1. JTONE seriesIt is strictly prohibited to turn on the ultrasonic cell grinder when the amplitude lever is not inserted into the liquid (empty load), otherwise it will damage the transducer or ultrasonic generator.
2. The amount of cell fragmentation, duration, and power output for various types of cells need to be determined by users through further exploration and selection based on different types of cells. This instrument has a high output power. If using a amplitude lever with a diameter of 2, 3, or 6, the power should be reduced to avoid overloading and breakage of the amplitude lever. (Ф2、Ф3<300W，Ф6<700W)
3. Use of amplitude lever selection switch
The variable amplitude pole selection switch is used to match the frequency and impedance of different specifications of variable amplitude poles and generators. If the frequency of the transducer component is different from the impedance of the generator, ultrasonic waves cannot work. When using JY series new instruments or equipping new amplitude rods, the selection switch should be turned to the corresponding position. When the amplitude rod wears out, the switch can be turned until the ultrasonic work is normal. At this time, the gear may not correspond to the specifications of the amplitude rod.
4. The value displayed on the power meter is related to the voltage, the depth of the amplitude rod inserted into the liquid surface, and the concentration and consistency of the crushed sample. When the voltage is below 220V and the amplitude rod is inserted deeper into the liquid surface and the load concentration is higher, the displayed value may be slightly smaller, and vice versa (this data is a simulated parameter, and the size of the displayed value does not affect the actual power of ultrasonic emission).
5. This machine does not require preheating and should be properly grounded for use.
6. During ultrasonic fragmentation, due to the cavitation effect of ultrasound in the liquid, the temperature of the liquid will quickly rise. Users should pay more attention to the temperature of various samples. It is recommended to use short-term (no more than 5 seconds each time) multiple crushing, while also adding ice bath cooling or selecting our company's low-temperature cycle

Technical Specifications:

Ju Tong Electronic Analysis: The power transistor on the motherboard may experience a short circuit due to long-term uninterrupted use of the machine.

Suggestion for testing: When the power transistor is connected to the motherboard, use a multimeter to measure the resistance of the pins on both sides of the power transistor. Under normal conditions, it should be around 22 Ω. After removing the power transistor (disconnected from the motherboard), measure that there should be no connection between its pins.

4Cleaning Method
Industrial cleaning can generally be classified into the following three ways:
According to different requirements for cleaning accuracy, it is mainly divided into three categories: general industrial cleaning, precision industrial cleaning, and ultra precision industrial cleaning.
General industrial cleaning includes cleaning the surfaces of vehicles, ships, and airplanes, which can only remove relatively coarse dirt;
Precision industrial cleaning includes cleaning during the processing and production of various products, cleaning the surfaces of various materials and equipment, etc., characterized by the ability to remove tiny dirt particles;
Ultra precision cleaning includes ultra precision cleaning of mechanical parts, electronic components, optical components, etc. in precision industrial production processes, with the aim of removing extremely small dirt particles.
2. According to different cleaning methods, it can also be divided into physical cleaning and chemical cleaning: using the principles of mechanics, acoustics, optics, electricity, and thermodynamics, relying on the action of external energy, such as mechanical friction, ultrasonic waves, etc. The method of removing surface dirt from objects using ultraviolet radiation, steam, etc. is called physical cleaning; The method of using chemicals or other solvents to remove dirt from the surface of an object through the action of chemical reactions is called chemical cleaning. For example, various inorganic or organic acids are used to remove rust and scale on the surface of an object, oxidants are used to remove color spots on the surface of an object, and fungicides are used. Disinfectants kill microorganisms and remove mold spots. Both physical and chemical cleaning have their own advantages and disadvantages, but they also have good complementarity. In practical applications, the two are usually combined to achieve better cleaning results.
3. According to the different cleaning media, it can be divided into wet cleaning and dry cleaning: cleaning in liquid media is generally called wet cleaning, and cleaning in gas media is called dry cleaning. Traditional cleaning methods are mostly wet cleaning, while the more easily understood dry cleaning is vacuum cleaner. However, in recent years, dry cleaning has developed rapidly, such as laser cleaning, ultraviolet cleaning, plasma cleaning, dry ice cleaning, etc. The field of precision and cutting-edge industrial technology has experienced rapid development.
