Ionic contamination tester pcb
WebIonic contamination testing is required as ionic residues remaining on both the PCB manufacturing process and the soldering process may affect the reliability of a finished assembly. A Contaminometer measures ionic contamination by essentially immersing a sample in a test solution of propanol and de-ionized water to dissolve the contaminants. WebIonic contaminants are remains of flux that are left behind during the assembly process. Ionic compounds are held together by electrostatic forces and the compound itself has a …
