Cleanliness Testing

CM+ Series Ionic Contamination Test System

The Gen3 Systems CM+ Series, Award-Winning, Ionic Contamination Test System is the Industry’s first combined ROSE and PICT Ionic Contamination Tester.

downlode-broucherCommonly referred to as “Cleanliness Testing”, the Contaminometer is the most advanced system developed to measure ionic contamination. This test method, for more than 40 years, has been recognized as an important Quality Assurance and Process Control tool in the manufacturing of electronic components and Printed Circuit Boards (PCB) and Assemblies (PCBA).

International Standard IPC J-STD-001 traditionally states that assemblies shall meet a cleanliness value of <1.5µg/cm2 of NaCl equivalence.  Gen3 Systems, and this newest CM+ design, is directly connected to the introduction of the new process control metric referred to as: Process Ionic Contamination Testing (PICT). The new CM+ Series has the capability to measure the amount of Ionic Contamination in accordance with all current test methods, commonly referred to as ROSE (Resistivity of Solvent Extract) testing, as well as the new PICT test.

The system has also been designed to avoid polarization effects between electrodes, as may occur when utilizing DC test currents.  The Gen3 Systems Contaminometer series is available in five (5) different models and five (5) tank sizes.  To optimize accuracy and performance, it is important to use the smallest possible tank size for the PCB/PCBA under test.

All the test selection ranges incorporate a solid gold test-cell, ballistic amplifiers and dynamic pump systems to ensure precision measurements, uniform even at low conductivity values. The system’s PC-based software produces graphical test data, Pass/Fail Analysis as well as hard copy reporting using test methods in accordance with industry standards
