Dear Martin,

Your Wave Solder Process class at our facility this month will stand out as one of the most notable events to take place here this year. We now have a much better understanding of our process control.

Our Optimizer usage was minimal at best. But now our new process plan is to verify parallelism on all 3 of our wave machines by implementing your straightforward and powerful Finger Marking Procedures, then to determine the best dwell time and immersion depth for each of our board types, and then to run our Optimizer to verify each board recipe before problems surface.

Your course was essential in showing us how to eliminate solder bridges in our process. The course taught us the exact way to establish parallelism on our wave machine, improve our dwell times and adjust our solder temperature. The concept of developing this type of "Optimizer recipe" for each of our board types is now a permanent fixture in our production planning.

We've now begun down the road of increased throughput and reduced defects. We're very certain that our excursion on this road will be a long and profitable one.
