CT-100 Contamination Tester

Ionic Contamination Tester

CT-100

The CT100 is designed to make simple and accurate ionic contamination test on big boards (up to 100×150 mm) in fully compliance with MIL-P-28809, MIL-STD-2000A, DEF-STD 10/03, IPC-TR-583, IEC Standards.

We can now offer here at Coventry a convenient ionic test facility. Please contact Elaine in the first instance by e-mail – elaine@blundell.co.uk

Ionic Contamination Tester

These measures are necessary to check the cleanliness of boards and assemblies after cleaning, or in case of new solder process parameters (no clean process, conformal coating, lead free alloy with new activator), for quality control and approval.

  • In humid atmosphere, the ionic contamination is transformed in electrolyte, catching moving ions which can create failures on electronic assemblies (dendrites, bad insulation).
  • The ionic contamination test will point out these risks, qualify assembly process and will extend product life and reliability.
  • Process is at first to clean efficiently the specimen using chemistry 2-Propanol and de-ionised water (75/25 or 50/50) while analysing continuously contamination development in the cleaning solution running in close loop tubing.
  • Measurements are driven by PC. The operator registers the sample dimension and dips it the tank.
  • The test is fully automatic and contamination results are given vs time.
  • The chemistry is regenerated after each test by filtration.
  • Test chemistry circulation is obtained using a free maintenance pump and a set of valve providing the possibility to switch from regeneration to test circuit.
  • Very sensitive conductivity cell (0,0001 μS/cm) with integrated temperature probe can detect very low contaminant even on very small samples.
  • Sophisticated software offers the possibility to record and compare results with International Standards.
