The Inside Story

The Most Expensive Defects
More than any other cost element, the cost of wave solder defects is misunderstood.  The problem is not only with “poor quality” wave soldering, but also with wave solder results that are generally considered “satisfactory” and even “excellent.”  Wave solder defects are the most expensive process deficiencies in the electronics packaging industry.  Read The Article

Determining The Cost Of Wave Soldering Defects At Your Facility
An opportunity to calculate the actual cost of your wave soldering defects.  Likewise, to document the cost savings achieved by the reduction and elimination of these expensive defects.
The ways in which defects increase your daily production costs can be identified and quantified.  Read The Article

Wave Soldering Myths and Facts
Touch up, rework, failure at ICT, scrapping, thermal profilers, glass plates, dip testers, changing solder, new flux types, bad board design, new wave machines, more preheater zones, air knives, new fluxers, deep machine maintenance…….Why all these tools, changes, activities and concepts leave you with board defects and frustration.  Read More

Dwell Time and Immersion Depth Are Crucial
Engineers report significant improvement in both board quality and repeatability when optimizing dwell time by board type.  This has led to dramatic changes in wave solder procedures throughout the industry.  Read The Study

Parallelism and Board Quality in Wave Soldering
Parallelism is the most widely recognized wave soldering parameter and among its most misunderstood. Our industry wide convention is to define parallelism as “rail-to-wave parallelism” or “conveyor-to-wave orientation.”  Both terms mislead process engineers and wave machine technicians, causing persistent board defects.  Read The Study

The Secret Technique of Marking Your Fingers
Measuring and adjusting your wave machines’ fingers allows you to easily eliminate finger variations as a cause of wave soldering defects.  This can demystify many of your repeatability problems. This simple technique can be implemented right now.  Read The Study


“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

“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

“Your company walked in here and quickly showed my staff how to reduce defects that we’ve had to live with for a long time.”

– Dennis Herrick, Director of Operations, Condor

“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

“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

“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

“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

“Using the Optimizer’s techniques every day on one board type, we saved 257 hours of touch up and rework per month.  This saved our facility over $50,000 in 12 months on this one board type alone.”

– John Lanferman, Process Characterization Group Leader, Celestica

“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

“Our main problem was recurring insufficients.  We made many attempts to address the problem, to no avail.  By using the Optimizer to graph our immersion depth, we identified and corrected turbulence in our main wave.  This has benefited our production process.”

– Jose Martinez, Maintenance Engineering Supervisor, Rain Bird
