An ultrasonic tank is a tank that has sound waves going through a bath. When these sound
waves run into an object (part), it forms bubbles that attach to the surface and pull off material
(dirt) and clean the object (part).

These sounds waves come in different sizes from large to small waves. Some parts will not come
clean with large sound waves and need smaller sound waves. We measure both large and small
sound waves to make sure that your tank has the correct soundwave size to clean your parts.
We use this information to certify your tank.

The image to the right is an ultrasonic tank with our probe that measures it's sound waves.

Is it a good wave or a bad wave?

              Good Wave                                Bad Wave

The bad wave tells us that there is something wrong with the tank..

Are There Many Cleaning Bubbles or Only a Few

                                                                Many Bubbles                                  Few Bubbles

The Video shows a concentrated bunch of soundwaves in 2 thousands of of a second. Due to the high concentration in an extremely short period of time, it is called a Burst. This Burst creates millions of cleaning bubbles.
The Pictures above shows a good cleaning signal and a poor cleaning signal

Is the Power of The Wave the Right One?

              Strong at 40kHz                        Weak at 40kHz

Is the Power the Same Throughout the Tank?

Consistent throughout the tank           Inconsistent throughout the tank

Ultrasonic Tank Certification Procedure

Our Certification Procedure is now used to validate many of the
major companies in the Silicon Vallley ultrasonic
cleaning tanks used in clean lines.

1.0   Objective
1.1   To validate the power distribution of an Ultrasonic Tank to meet Certification Standards.
2.0   Instruments used for Certification
2.1   TM Associates L-2001 Ultrasonic Probe
2.2   TiePie software
2.3   Watt Meter
2.4   Meter to check capacitance and resistance
3.0   Bath Preparation
3.1   Empty the bath and refill within 1% accuracy.
3.2   Degass the bath at 10 minute intervals until complete
3.3   Check Transducer Capacitance and direct resistance of the transducers
3.4   Prepare the Bath for the Hess Method
3.5   Measure the rise in the Bath's Temperature over time.
3.6   Hess Method
4.0   Tests to be run
4.1   Sine Wave Test at 40, 80, 120 kHz
4.2   Burst Test at 40, 80, 120 kHz
4.3   Spectrum Test at 40, 80, 120 kHz
4.4   Transient Test at 40. 80, 120 kHz

If we certify your tank you will get a full page report-
and a certification label like the one below to put on your tank.

Passing Tests Results for Sine Wave 40/80/120 kHz tanks
Note: Illustrates a consistant sine wave and measures actual frequency
40 kHz            80 kHz             120 kHz
Passing Tests Results for Burst Test 40/80/120 kHz tanks
Note: Shows a strong burst pattern at 1 ms with millions of cleaning bubbles.
40 kHz            80 kHz             120 kHz
Passing Tests Results for the Spectrum 40/80/120 kHz tanks

Note: The tall spikes show full power of each 40/80/120 kHz respectively
40 kHz            80 kHz             120 kHz
Passing Tests Results for Multi-power positions of 40/80/120 kHz tanks
Note: This shows consistent power of multiple areas of the tank and defines which areas are optimal for cleaning or chemical mixing
40 kHz            80 kHz             120 kHz
These show consistent power in all areas of the tank, front back, and middle
