Ionic Contamination Test System – Omegameter SMD 650

About the Ionic Contamination Test System – Omegameter SMD 650

From SCS, the name synonymous with automated ROSE (Resistivity of Solvent Extract) testing systems, comes the SCS Omegameter — an industry standard for accurate, efficient and practical quality Omegameter test systems from Specialty Coating Systems (SCS) are the industry standard for determining ionic contamination on printed circuit boards and assemblies using static test methodology. In fact, SCS' name is synonymous with automated ROSE (Resistivity of Solvent Extract) testing systems, which enable manufacturers to test for contamination, as defined by IPC-TM-650 (Test Method 2.3.25), for the purpose of process control.

The Omegameter SMD 650 utilizes the static extraction method to measure resistivity change when a substrate is submerged in ultra-pure test solution. The amount of change in resistivity indicates the level of contamination, which is often the result of residues from upstream manufacturing processes.

The Omegameter SMD 650 offers manufacturers the ability to test components non-destructively with a heated or non-heated test solution. IPC-TM-650 describes the benefit of a heated solution to "accelerate and improve the efficiency of extraction of ionic material from poorly accessible regions, such as under surface mounted components." In addition to increasing efficiency, a heated system also ensures temperature consistency of the test solution, whereas solution temperature in an unheated system can vary due to environmental conditions and the natural warming of test solution during recirculation. Variation in temperature yields less reliable results.

The software-controlled Omegameter SMD 650 provides unlimited storage of test profiles, which can be customized for easy identification by operators. Additionally, the software stores test results that can later be viewed, sorted, filtered, printed as full-size PDF files and/or exported into a spreadsheet for further analysis. Operator-specific privileges may be established through the use of password-protected user accounts.

The first static test system on the market, the SCS Omegameter has a long history of being an accurate, effective and practical quality assurance tool. The Omegameter SMD 650 continues this strong product legacy as the most trusted name in the industry.
