Should I use coherent or fan style nozzles or does it matter?
I think it depends. If you have a rotating type spray system, you will want to use the fan type nozzles. If you have a set basket that you’re spraying and sitting vertically, I think you could use a coherent jet. To give you impingement at the board level, I think coherent jets do best cleaning because they are a lot higher pressure and do a better job of cutting a river or channel, or underneath your components. It just really depends on what your system is. Fans for the most part are rotating and if you have vertical sprays, a combination of both will do an excellent job.
