can we use same reflow oven for lead free and leaded solder paste, is there any chance of lead contamination in lead-free products.

You can most certainly use the same reflow oven for both leaded and lead-free pastes. Obviously your thermal profiles will be different, as the lead-free paste should have a higher reflow temp. As long as your oven has adequate exhaust and flux manag

Hello We are currently cleaning stencils from both process (PbSn and lead free) in the same cleaning machine. A customer is concerned about cross contamination of lead between stencils. Is there any test kit or tool that you can suggest to test the

I think OA flux left on the pot would quickly looses its activity and become part of the dross waste stream, and smoke stream for that matter. Also, if your wave is setup properly your selective pallets will scour (push) the top of the lambda wav

Is anyone aware of any white papers regarding the possibility of lead contamination on ROHS assemblies from using the same test fixture with the same test probes on both tin/lead and ROHS assemblies. We have customers switching over but we are still
