We run trials with folks from ERSA. Actually, due to their knowledge, erosion of the solderpot, the wave-nozzle, and the pump are considerable. However, new equipment seem to be produced lead-free save with coated stainless steel. It seems also as if it is possible to cover the parts in danger with a organic coating (paint) which can be done during the downtime when a service is done. The coating needs a refreshment every one or two years I heard though one line with that coating seems to run now three years in 24 hours shift without problems. What we also looked at are upgrade kits for older equipment. I am right now writing a cost- evaluation.
