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 daily basis, I'm using a Wave Solder Optimizer (made by Technology
Information Corporation) for measuring preheat and wave dynamics (height,
width, parallelism).

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.

Subject:  [TN] SPC @ WAVE SOLDER


In regards to SPC at wavesolder. 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. Thanks.
