Cleaning system is used to clean particles and contaminants in the manufacturing process of precision equipment, semiconductors, displays, and other products. If cleaning equipment is not used properly, defective products and yields may occur frequently.
There are a wide variety of cleaning methods, including ultrasonic, spray, brush, dry, and solvent cleaning.
Cleaning systems are used in a wide variety of applications, especially in the manufacturing process of precision products.
In selecting cleaning systems, it is necessary to consider the size of the contamination and the object to be cleaned, the cleaning time, and the cleaning accuracy. Taking these factors into consideration, the cleaning method, the cleaning agent to be used, and the drying method must be selected. The following are examples of cleaning equipment use.
The following explains the principles of ultrasonic, spray, brush, dry, and solvent cleaning systems, which are the most common types.
Ultrasonic cleaning equipment cleans by placing the object to be cleaned in a solvent and vibrating the inside of the solvent with ultrasonic waves. The magnitude and frequency of the vibration must be selected according to the object to be cleaned.
Spray washers clean objects by spraying gas or liquid from a nozzle. Handheld type cleaning equipment is also available, so it can be used even for large objects to be cleaned.
Brush cleaning equipment uses brushes to remove contaminants and then rinses them away with a solution or spray cleaning. Because it uses brushes as a physical method of cleaning, it can clean difficult-to-remove contaminants.
Dry washing equipment irradiates UV light to the object to be cleaned to generate ozone and active oxygen, which react with the contaminant to remove it. They are mainly used at semiconductor and display manufacturing sites.
Solvent cleaning equipment uses the dissolving power of solvents to dissolve and remove contaminants. Care must be taken because extremely hazardous solvents are used in some cases.
