Semiconductor manufacturing involves a large number of process steps that etch silicon wafers and deposit thin films. Between the steps, the silicon wafers have to be cleaned to remove traces of chemicals and particles in preparation for the subsequent step. Cleaning is usually done with powerful chemicals such as acids and peroxides that remove undesirable […]

Parts with hard surfaces such as those made from steel or brass are easy to clean with ultrasonic cleaners and low frequencies can clean these parts very quickly. For aluminum parts, getting rapid and effective cleaning without damaging the parts is more difficult. Aluminum is a softer metal and surfaces can suffer pitting in ultrasonic […]

In industrial ultrasonic cleaning systems, a generator produces the electric high-frequency signal and a transducer converts the signal into physical sound waves in the cleaning solution. Depending on the application, ultrasonic cleaning transducers can handle different frequencies and deliver enough power to fill the cleaning tank with ultrasonic waves. For existing tanks, moveable immersible transducers […]

1. When Should I Use an Ultrasonic Cleaner? You should use an ultrasonic cleaner when you want quick and complete cleaning action without the use of harsh chemicals or mechanical scrubbing. To get the best possible performance, it is important to choose the right type of ultrasonic cleaner. Key cleaner characteristics include the frequency, power, […]

Disk drive components such as the aluminum disk platter blanks and the metal read/write heads are manufactured in standard industrial facilities. The processes for their fabrication include stamping, machining, punching, polishing and molding using industrial chemicals for cooling, lubrication and as abrasives. Although most of these chemicals are removed in the final stages of manufacturing, […]

Ultrasonic cleaners quickly remove contamination from part surfaces, but using the right frequency is important. If the ultrasonic frequency of the cleaning system is too high, cleaning could be less effective and take longer. If it is too low, delicate parts could be damaged. Ultrasonic cleaning systems are extremely versatile and can excel at most […]

Ultrasonic generators produce the high-frequency electrical signal that powers the ultrasonic transducers immersed in the cleaning solution. The transducers are passive in the sense that they merely convert the electrical signal into sound waves. The generator handles all the control functions and is responsible for determining the frequencies used, the power output and the frequency […]

Machined parts come out of production contaminated with a variety of substances. If they have been machined using lubricants, traces of these may remain on the part. The parts may pick up dirt from the shop environment and machining sometimes leaves particles on the machined surfaces. Such contamination is especially harmful if the machined part […]

While selecting the right operating frequency for industrial ultrasonic cleaners is important, the equipment size and options are critical for obtaining excellent cleaning performance. Depending on the cleaning application, either a flexible system or a system designed for one particular task may be best, and selecting the corresponding options will influence how the system can […]

Ultrasonic cleaning is an excellent solution to many cleaning applications. The ultrasonic process removes contaminants from a variety of parts and works without strong, aggressive chemicals. It is compact, needing only a tank slightly larger than the parts to be cleaned, and it works more rapidly than other cleaning methods. Ultrasonic cleaning is completely safe […]
