Although commonly referred to "Cleanliness Testing"
it is in fact a measurement of ionic contamination.
This test method has, for over 40 years, been acknowledged
as an important Quality Assurance and Process Control
tool in the manufacture of electronic circuit boards,
components and assemblies.
IPC-J-STD001 requires that assemblies be cleaned to
a value of <1.5µg/cm2 of NaCl equivalence.
The CM Series utilise a solid gold measuring cell, ballistic
amplifier and a vigorous pumping system to achieve superior
measurement accuracy of <0.005mS/cm even at very
low conductivity values. The CM Systems have been designed
to avoid polarisation effects between electrodes as
might occur when using DC test currents.
CM11 and CM12 are the smallest and most economic test
system of this type in the world.
CM60 is a floor-standing system that includes our unique
Volumetric Measurement Cell (VMC) that automatically
calculates the surface area to be tested by the volume
of test solution that is displaced when the item is
put into the test tank. This allows for a far higher
level of precision and provides for more quantitative
test data than other methods.
