Cleanliness Testing/ Ionic Contamination Testing - CM Series

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.
