Ion chromatography technique leads to cleaner PCBs
PCB cleanliness can be evaluated in accordance with the latest industry standards using a variety of test techniques. In Zestron's Analytical Centre one of the comprehensive methods applied is ion chromotography. This highly sensitive analytical method provides a detailed report of anions, cations and weak organic acids on PCBAs according to IPC-T-650 2.3 28A.o
It enables critical substance such as bromide or chloride and their amount to be determined.
Compared to simpler measuring methods such as Contaminometer or Omegameter, where only the whole ion content as equivalent to sodium chloride is built, the ion chromatography provides a quantitative and qualitative measurement of single ions.
Potential failures such leakage currents, electrochemical migration or corrosion of cupper contacts can be assessed.
The ion chromatography is suitable for both, the evidence of cleanliness after soldering according to guideline and to qualify surfaces after cleaning respectively before coating or bond processes.
