Why Not Other Methods?

Traditional methods of wave solder process control focus on the wrong parameters and are inadequate for measuring the data points that are most important to your board quality.

Older methods like thermal profilers, dip testers and glass plates cannot produce reliable measurements, true repeatability or real optimization of the key wave soldering process parameters. They do not effectively or accurately measure the most critical parameters for wave solder excellence: Dwell time, immersion depth and board-to-wave parallelism.  Regardless of any adaptations or add-ons, they do not measure temperatures in a manner that is both convenient, accurate and suited for the wave soldering process.  They do not give any gauge of fluxer performance.  They do not measure the essential immersion depth data point that most affects board quality.

To the extent they are used for these parameters, measurements are highly subjective and broad, depend on theoretical wave models, make unsuitable use of temperature movements or are dependent on human reflex and visual observation.  This specifically applies to thermal profilers that have been adapted in an attempt to use thermocouples and hypothetical wave shapes for estimating how your boards may go through your solder waves.  The result, regardless of your actual defect rate, is exaggerated production costs, impaired assembly quality and staff frustration.

You know this to be true if you have been doing “all the right things” yet still suffer from defects and inconsistent board quality and all the aggravation that comes with it.  In fact, nearly all of our customers already own a thermal profiler or glass plate, or both, when they decide to invest in the Wave Optimizer.

Further, the Wave Optimizer’s easy user interface is one of a kind and widely acclaimed, designed for daily, hassle free use by your entire wave soldering team.

The Wave Optimizer’s precise and true data enables you to identify the exact optimal parameters for any PCB assembly.  Correlation of Wave Optimizer data with your board quality will clearly show which combination of dwell time, immersion depth and contact length produces the lowest defect rate for each PCB assembly you wave solder.

Because the Wave Optimizer produces electronically documented measurements, you will have a consistency and resolution in your process previously unattainable.  This means a fast and significant reduction in your defects and daily operating costs.

“I have worked with wave solder machines for years and can honestly say that this was the most informative and thorough class that I have attended on this subject.

– Dale Shedd, Process Engineer, Adtran

“The Optimizer identified the root cause of chronic skipping on our boards.  We eliminated the disparallelism it measured.  This had an immediate, positive effect on board quality.”

– Aldrina Paredes, Training manager, Bose Electronics

“Your instructor solved our excessive solder and bridging by adjusting our process based on our Optimizer’s data, and showed us how we can easily do this by ourselves.”

– Gary Wirth, Production Supervisor, Honeywell

“The proactive nature of your methodology, which allows us to identify board defects and production issues before they happen, is critical for raising yields.”

– Luis Lopez, Operations Manager, Benchmark Electronics

“Your wave soldering seminar gave us concrete methods and procedures completely different and beyond anything we’ve ever heard or seen from other vendors or ‘experts’.”

– Juan Guevara, SMT and Through Hole Manager, Alps Automotive

“We thought we had tried everything possible to eliminate a bridging problem.  Using the Optimizer, in only a couple of minutes we got rid of the bridging completely by adjusting the dwell time.”

– Alfred Santilla, Wave Solder Supervisor, Universal Lighting

“Many of our voids and insufficients were assumed to be design defects.  Your training instructor used our Optimizer’s measurements to make adjustments easily and now we should never see these defects in our production again.  What a relief!”

– Enda Moran, manufacturing Manager, CEL

“Prior to investing in the Optimizer, we relied on a thermal profiler but we could not solve our skipping and insufficients problems.  In fact, those defects were not due to improper temperatures at all but instead to how our boards run through our solder waves.”

– Ricardo Soto, Process Engineering Manager, Tyco

“The Optimizer made us re-think how we should wave solder.  We shouldn’t blame the board design as often and we cannot rely on a thermal profiler to control our wave process.”

– Martin Orozco, Process Engineer, TRW Automotive

“In all my years in PCB assembly, I have never seen such an enthusiastic response to a training program.  Other vendors never really improved our problems like you have.”

– Luis Velazquez, Engineering Manager, Plexus
