CM Series (Contaminometer™) Cleanliness Testers Description:

For over 40 years the Benchmark for Ionic Contamination Testing

Commonly referred to "Cleanliness Testing" as 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.

The Contaminometer (CM Series) test systems were originally developed by Protonique, the business of industry guru Brian Ellis. They also featured in the early development programmes of "cleanliness measurement" carried out by the US Department of Defense at China Lake in the 1970s.

Contaminometers are used to measure the amount of ionic contamination, usually referred to as cleanliness level, in accordance with IPC/ANSI-J-STD001 and UK DEF-STD and other international specifications. The instruments are also commonly referred to as ROSE (Resistivity Of Solvent Extracted) or SEC (Solvent Extract Conductivity) testers.

CONTAMINOMETERS from Gen3 Systems come in 4 different models and 4 different tank sizes because when selecting a Test System, it is important to use the smallest possible tank size for the circuit under test.

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.

PC based software is used to produce graphical test data, a pass/fail analysis and automatic hard copy print out using test methods according to the prevailing standards.

CM Features:

  • Unique solid gold measuring cell, ballistic amplifier providing a test accuracy of ±0.005μS/cm
  • Unique CURVE-FITTING Analysis algorithm (Merit of Fit)
  • High-speed testing in 3 minutes
  • Full regeneration in typically < 6 minutes
  • Accurate measurement even when the ratio of board surface area to test solution volume is very large
  • Automatic temperature compensation
  • Measures in accordance with all international and MIL specifi cations old and new
