Ionic contamination testers

DESCRIPTION:

The CT10, CT100 and CT1000 are designed to make simple and accurate ionic contamination test in fully compliance with MILP-28809, MIL-STD- 2000A, EF-STD 10/03, IPC-TR-583, IEC Standards...
These measures are necessary to check the cleanliness of PCBs 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 with leakage currents...).
The ionic contamination test will point out these risks, secure accordingly assembly process and will extend life duration, reliability of end product. Process is at first to clean efficiently the specimen using chemistry 2-Propanol and de-ionised water (75/25 or 50/50) while analyzing continuously contamination development in the cleaning solution running in close loop tubing.

USE CASES

- Case STPI
