I want to thank 48 Rotchild St. P.O.B 277 Rishon Le Zion 75200, ISRAEL and their trainer for the excellent training course in wave solder process control delivered on Feb 15-16, 2001.

Our classroom participants included some of our process engineers and wave solder operators. Their wave soldering experience ranged from 7 months to 15 years. I have worked with wave solder machines and the soldering process since 1987 and can honestly say that this was the most informative and thorough class that I have attended on this subject.

The class covered the science of wave soldering and all of its parameters, both internal to the machine and external to the machine. This information was shared with us in a manner that allowed our most inexperienced to the most experienced attendees to gain a wealth of useful information along with the guidance to use it for our in-house processes. I learned the importance of pH balance in the flux which has made me reconsider the way I view fluxes and the part they play in the soldering process, as well as strengthening and expanding the knowledge that I have accumulated over the years.

The implementation of the Wave Solder Optimizer into our process during the course showed details of our process that could not be seen without it. We took readings on the first day of class and recorded and evaluated the results. The next day we took more readings with the same settings on the machine and discovered the immersion depth had dropped significantly. Upon further investigation we learned the dross had been cleaned from the pot and the solder volume was low. By adding the amount of solder needed to return to its normal level, we regained the loss of immersion depth we had the previous day. Outside of its ability to record parameters of the solder wave as the board in transit sees them, this ability to trouble shoot a machine for mechanical/supply needs is great. The accuracy of the Wave Solder Optimizer is more than impressive.

Sincerely,
Dale Shedd, Process Engineer
