we have a new ersa ews500 wave machine and are experiencing difficulty in profiling for lead free. particular issue is reaching 110c preheat for large TH electrolitic caps while maintaining 110-170c on 1/4 watt resistors in same area

we have 4 bottom IR heaters and a 2 zone bottom Quartz heater (2 lamps/4 lamps) and 1 convection heater above zone 1 IR. we have very tight restrictions from customer and I could send profile view to your email if possible

So are you saying that you cannot reach 110C at 1 location without raising another location to excessive preheat temp? If so, sometimes slowing down the conveyor and dropping the preheat temps will help you get equal temps. I do not know this machi
