Agreed! The sprayed flux volume is critical to effective soldering, being able to measure and control it is extremely important. It's almost amazing how many reputable assembly companies do not understand the effect of too much or too little flux and it's effect. The same goes for pre-heat.

On a monthly basis, I'm using a Spray Flux Fixture (made by Vitronics-Soltec) for measuring flux volume sprayed. I (the operators) track both with SPC software. If used and understood, both tools are extremely valuable. Al Kreplick Sr. Mfg. Eng.

I would just like to here from some of the people in this forum on what type of data they are collecting or sampling. Any info is beneficial.
