Can anyone make sense of the claim that N-hexane dries faster and therefore suppliers using it can clean more screens per unit time and thereby save money? That seems ridiculous on the face of it since it's hard to imagine a task easier to do in parallel than wait for screens to dry. Heck, imagine it took 24 hours for screens to dry after being cleaned with alcohol - you'd just make that cleaning the last step on the line, stack the product into your staging trays with the screen still damp, let them dry overnight, resume the process from there the next day. Sure, it takes longer before the first piece comes off the line, but that's in the noise - after that you're producing units at the same rate with a one-day delay as you'd be producing with a one-minute delay. No?
