Precision ionic contamination measurement systems — Ionograph BT, Ionograph SMD V, and Omegameter — for PCBs, bare boards, and assembled electronics conforming to IPC and MIL-STD standards.
Ionic contamination on PCBs can cause electrochemical migration, corrosion, and premature field failures. Measuring cleanliness after soldering, cleaning, and rework is critical for aerospace, defense, automotive, and high-reliability electronics per IPC-7711, J-STD-001, and MIL-STD-2000A.
Batch ionic contamination tester for PCBs & bare boards
The Ionograph BT measures the total ionic contamination of PCBs and assemblies by extracting ionic residues in a closed-loop IPA/DI water solvent bath. The conductivity change is measured and converted to NaCl equivalent (μg/cm² NaCl eq.) for pass/fail determination against IPC and MIL-STD limits.
Localised ionic contamination tester for SMD assemblies & fine-pitch components
The Ionograph SMD V uses a localised extraction chamber (omega cell) pressed directly onto the PCB surface to test specific areas — ideal for SMD assemblies, BGAs, fine-pitch ICs and areas under shields. Eliminates the need for full-board submersion, saving solvent costs and enabling targeted testing.
Resistance-based ionic contamination monitoring system
The Omegameter measures ionic contamination by monitoring the electrical resistance of the IPA/DI extraction solution. As ionic residues dissolve, solution resistance drops — the system converts this to an equivalent NaCl concentration for quick, reliable cleanliness verification of production boards.
