Can Water Be Used to Clean Anything that Solvents Can Clean ?
What you are really asking is about the versatility of the two types of cleaning systems. In general, solvent systems will be more versatile than aqueous cleaning systems. Let’s look at the options: • Effectiveness: Many common types of contamination are not soluble in water, so no amount of water, pressure and heat can remove them. However, since Vertrel® is much, much heavier than water it can remove sold contamination even if it cannot dissolve it: it simply “floats” the dust and grit off the surface, just as a ship floats on the ocean. Solder balls are easily cleaned in solvents. The platters inside disk drives must be perfectly clean; solvent systems easily remove the tiny particles of dust and dirt which accumulate on those surfaces during manufacturing. Seminconductor makers also use solvents to clean wafers at different times in their processes. • Size & Spacing: The problem here is surface tension. Because the surface tension of water is high, aqueous solvents typically have d
