Why Do Ionic Testing ?

The fabrication and assembly of printed circuit boards (pcbs) includes many processes that introduce corrosive ionic materials to the pcb. There are many sources of these ionic contaminants, but most are attributed to chemical etchants and cleaners, plating solutions and solder flux. Ionic contamination can cause corrosion and dendrite growth…

What is the ROSE Test?

The Resistivity Of Solvent Extract (ROSE) test is a test for the presence and average concentration of soluble ionic contaminants. The process uses an extracting “Test Solvent” of 75 percent by volume of ACS reagent grade IsoPropyl alcohol (IPA) and 25% by volume of De-Ionized water (D-H2O). The alcohol is…

Test Solvent Quality

The concentration of IPA in the Test Solvent will influence the test results. The Test Solventshould be 75 % IPA, +/- 3%. Because IPA will evaporate quicker than H2O, the concentrationof IPA will tend to decrease with time. This concentration should be checked, and if necessaryadjusted, periodically. Non-ionic contaminates such…
