How to choose the
appropriate
frequency of an ultrasonic
cleaning?
For
cleaning application,
the
frequency
performance of
ultrasonic energy can be
described as,
Low
frequency, the impact
more stronger;
High
frequency, the
penetration ability is
better.
Could use the broom to
do metaphor,
Low
frequency
- like a large and hard
plastic broom, for the
large size garbage clean
up very quickly;
High
frequency -
like a thin and soft
brush, for the small
size of dust clean up
very clean, and will not
wear the surface.
Different
ultrasonic frequency
specifications are like
many sizes of brooms
available for selection.
The following are some
application examples of
different
ultrasonic frequencies,
for reference only.
25KHz or 28KHz, the
metal parts cleaning;
40KHz, the glass
cleaning;
68KHz, the
electroplating of metal
parts cleaning;
133KHz, the
electroplating of quartz
glass cleaning;
300KHz or 1000KHz, the
wafer cleaning, etc. |
