ROSE test
From Wikipedia, the free encyclopedia
The resistivity of solvent extract (ROSE) test is a test for the presence and average concentration of soluble ionic contaminants, for example on a printed circuit board (PCB).[1][2][3][4] It was developed in the early 1970s.[5] Some manufacturers use it as part of Six Sigma processes.[3]
Some modern fluxes have low solubility in traditional ROSE solvents such as water and isopropyl alcohol, and therefore require the use of different solvents.[6][7]
