What are the factors affecting the cleaning effect of sonic cleaner?


In general, ultrasonic cleaning effects with ultrasonic cleaning machines (such as power, frequency, temperature, pressure). There is also related to the selection of ultrasonic cleaning time and cleaning liquid.  The cleaning effect of sonic cleaner will be different if you use a different frequency.

For example, you use a cleaning agent, sulfuric acid, and water for sonic cleaner before the epitaxial growth of the silicon wafer. The sonic cleaner can achieve a better cleaning effect when the ultrasonic power is higher than 250W.

1. Cleaning Time of sonic cleaner

The time setting of cleaning will be different depending on the different components and products. Set the appropriate time is conducive to saving time and achieving the best cleaning effect (general set time is 10-20 min),

If the time is too short, the workpiece cannot be cleaned. Time excessively causes cavitation spots on the surface of the cleaning sample. This will affect the surface finish.

2. Cleaning temperature of sonic cleaner

Since each device is different in its physical characteristics of each device. So we should select different cleaning temperatures during cleaning, such as oil, usually more than 50 ° C. Aluminum parts, generally choose about 40 ° C. If the temperature is too high, the oxide spot will be formed. The generally selected 15 ° C below the burr is suitable.

Blue Whale Ultrasonic cleaning equipment has a heating automatic thermostatic system, 20-80 adjustable. It can be freely set to ensure that different products are not damaged at a fixed temperature.

3. The frequency of sonic cleaner

Ultrasonic frequencies are typically between 25kHz to 130kHz. When using water or an agent of sonic cleaner, physical cleaning force caused by holes is obviously advantageous to low frequency, generally from 15-30 kHz. It can clean the part of the gap, slit, and deep well. Better use high frequency (generally 40kHz), or even hundreds of kHz. 400kHz is more appropriate when cleaning the clock parts.

4. Ultrasonic power of the sonic cleaner

The ultrasonic power of a standard sonic cleaner range from 100W to 3600W. High-power products are mostly used in the cleaning of general objects such as hardware, mechanical and other industries or severe pollution.

5. Cleaning agent of sonic cleaner

Select the correct cleaning solution to help the parts clean. Conventional cleaning solution (medium) is a water-based solution, alcohol, gasoline, and other organic solutions. The current ultrasound cleaning agent is a mixture of various detergents, wetting agents, and other reactive components.
