Ultrasonic PCB Cleaning

Ultrasonic cleaning machines use high-frequencies to cause cavitation; the violent implosion of billions of minute bubbles in the cleaning solution contained in an ultrasonic cleaner tank. The bubbles are created by transducers bonded to the bottom of the tank and excited to ultrasonic frequencies by generators. The implosion of these bubbles blasts away contaminants on the surface of parts being cleaned.

Ultrasonic can be defined as sound waves that have frequencies above the upper limit of the normal range of human hearing, which is about 20 kilohertz (20 kHz or 20,000 cycles per second). While that is true, ultrasonic cleaners when operating can be heard due to the action created by what we call ultrasonic cavitation.

Why Need PCB Ultrasonic Cleaner?

The ultrasonic cleaning process can reach the most difficult, hard to reach places underneath high density components on most any parts of a circuit board. This is not the case for SMD devices that have small gaps that are smaller than the surface tension coefficient of the cleaning fluid. However, the process is fast and there are numerous high-capacity machines available to address high-volume cleaning needs.

An ultrasonic cleaner that absolutely removes all traces of flux residue off of my PCBs. flux residue has a negative impact on signal integrity. Cleaning with flux remover, isopropyl alcohol and tooth brush improved the SI but I can still see under microscope that there are still traces of flux residue between vital IC pins. As tested USB 3.0 protocol analyzer showed packet error count go down from 1000 to 100 after the manual cleaning, that is why PCB ultrasonic cleaner is needed.


PCB Ultrasonic Cleaners

Cavitation is not a gentle process. It has been calculated that temperatures in excess of 10,000°F and pressures in excess of 10,000 PSI are generated at the implosion sites of cavitation bubbles.

Measured in cycles per second, ultrasonic cleaners can produce from 25 kHz to 100+ kHz. Lower frequencies create larger cavitation bubbles compared to higher frequencies. Larger bubbles implode more vigorously and are used, for example, to remove gross contaminants from fabricated metal components. Higher frequencies create smaller bubbles that clean more gently but are better able to penetrate cracks, crevices and blind holes. The higher frequencies are used for cleaning highly polished or delicate surfaces.
