I have some questions on the consistency of readings that people are getting using devices like the Optimizer and Wave Rider. 1. What sort of variations are you seeing from run to run and day to day in parallelism, immersion depth and conveyor speed? 2. What variation do you allow in these areas? 3. What wave solder machine do you use with your device? We have a Technical Devices machine and using an Optimizer we see some pretty good swings day to day, particularly in the parallelism.
