We are starting a lead free line. My question: Is there a contamination issue with running lead free boards and lead boards after soldering through the same board wash machine? I would expect not it, but want to know if anyone has any experience with this. Thanks ~Jeff~

No, there are no issues with mixed lead / no-lead post-reflow cleaning. No-lead is a little harder to clean so be sure you use the appropriate parameters and cleaning chemical.

The only potential issue is if you mix up the boards after cleaning, inadvertently mistaking lead-free for lead.

So as far as pb free compliance in EU there would be no residuals from pb on the pcb's to speak of. We also have deionization cabinet with chealate filter for heavy metals that recirculates the wash water.
