Steve, As usual you are the expert. How do you remember where to find all this stuff? I need to update your link for the cookson white paper: http://www.speedlinetech.com/DOCS/White_Papers/EquipmentImpactsofLeadFreeWavesolderingAPEX2003BestUSPaper.pdf I am planning on replacing the current machine. It would take too many modifications for lead free.

You have more than just the pot to worry about, pumps, nozzels, ducting are things that can get eaten-up as well. At this past APEX, there was a good paper published called; "Equipment Impacts of Lead Free Wave Soldering" that can be a good reference. It's at: http://www.cooksonee.com/DOCS/White_Papers/EquipmentImpactsofLeadFreeWavesolde ringAPEX2003BestUSPaper.pdf And another good resource is at: http://www.alphametals.com/products/lead_free/tech_art.html Hope this helps, -Steve Gregory- > Good morning, > > I have been given the task of finding out what is needed in a wave solder > machine to go lead free.
