I know it's reflow I misspoke, we have ours wave soldered, because we still use a lot of thru hole components. I am not saying your product is bad, that you don't use checks on your equipment I am sure you do (especially after seeing the load tester for one of your ESC’s. in another thread
). I think you make a great product, I never said anything to the contrary. And I am not saying you don’t use top of the line equipment, I have worked with many AOI systems (nothing is perfect) as well integrating them in systems we build.
I know first hand about conformal coating and lead free, we are just not there yet. (We don’t sell overseas). To me if the joints at the inductor failed as you described it would have left one of the leads behind. Maybe it did I was just using my experience to make an informed theory on what might have happened.
I understand the amount of shock that these things are subjected to, and you probably have more solder needed for that purpose (since it is known that that is what is going to be subjected to). I understand that you take quality seriously I have read about the exemplary customer service that you have. That’s why I bought my Mamba Max, and in the near future a MMM or a Mamba Max pro for RC and an industrial application in the works.
In my line of work I have seen just about everything (because as soon as you say it, something else comes along) as well I have been with the same company for nearly 15 years and do a lot of repairs, I have seen my fair share of defective components, absolutely wrong installations, people that think the A/D card needs 110 plugged into it, lightning strikes, forklift damage, cards sent in without a thing wrong with them. People who have no business trying to troubleshoot a piece of equipment using a DMM, or any real clue what the problem is in the first place (The old it’s broke, it don’t work deal). Again I am not bashing your product, but to have the same failure mode to me would raise a flag.
