Wave Solder Pot Contaminated with Lead

Postby Molly O'Hara » Mon May 14, 2012 9:30 am

Question: "Our wave solder pot contains lead free solder. Analysis indicates it contains 0.12% lead. The maximum allowed is 0.10% lead.
Is there anything we can do to promptly bring the lead concentration into compliance?"
E. C.

Answer from Sunstone Circuits: The most efficient method to bring the solder pot back into tolerance would be to decant about 50% of the pot and replace it with lead free solder. This should work for a period of time until the lead level grows again.
