SME-500S is a tester specially designed for testing the ionic contamination content on the surface of PCB\PCBA.
According to the method of ionic contamination degree test defined in IPC-TM-650, the test process includes 3 processes: solvent regeneration, ion contamination solvent extraction and ion contamination degree measurement.
SME-500S adopts a high-purity, high-capacity ion exchange device. Before each test, the solvent is regenerated through the ion exchange device according to the setting value to ensure that the ion content in the solvent meets the test requirements before each test.

1. Using high-precision data collection and detecting measurement system, no solvent polarization phenomenon, to ensure the accuracy of the test.
2. Automatic calibration function, no need for complicated calculations.
3. Special regeneration device, fast regeneration and long service life.
4. Automatically adjust the liquid level according to the size of the PCBA/PCB, both large and small boards can be tested.
5. The size of the test tank can be customized,
6. Fully enclosed test environment to reduce the influence of CO2 on the test results.
7. Immersion spray wash PCBA/PCB to ensure complete extraction of ionic contamination.
8. The operating software is simple and intuitive. The testing process is fully automatic.
9. Fully compatible with international standards MIL-P-28809, MIL-STD-2000A, DEF-STD-10/03, etc.
