The short answer is you really want to make sure you get the rinse water in the components in the vented package and then back out. Common techniques beyond just the inline or the batch washer or the sprays is to repurpose your old ROSE test or megameter machine where you immerse in the IPA water solution and submerge it and then allow that to penetrate in the component package and come back out. Another thing that we really recommend is a bake out cycle depending on the temperature that’s allowed for the parts. Sometimes a 4 to 8 hour bake out cycle will deactivate any amines or other residues that might be left in that package.
