Can lead free components/assemblies be contaminated if reflowed in a reflow oven for leaded process?

I have only one reflow oven can I use it for both processes (leaded and lead-free)? If I do use it, one run for leaded and the next run for lead-free will that contaminate my lead-free process?

Hi, I think you should be ok, as the contamination in a reflow oven is generally flux from what I have seen. I have never heard to the solder metals itself being inside the oven apart from some paste in hole we did that sometimes dropped a bit of so

I don't think so. But I want to point out the amount of lead needed to contaminate a joint is microscopic. You won't have lead vapour in your oven and with a clean oven there probably isn't any other way for even a microscopic amount of lead to con

Contaminate your Leadfree Process with WHAT? What contamination are you concerned about? Its an oven - it doesnt care what you put in it... Your main concern is that you can achieve the desired Leadfree Profile...dont be confused or concerned whe

Hi smtspecialist (man I gotta get me a name soon), NO! Your oven cannot contaminate your process. Unless you have flux residues dripping on your board, there is nothing to worry about. Now having your operators switch from leaded to lead-free smo

Looks like early experiments using lithium as a lead replacement in a nitrous oxide atmosphere may have had some side effects.......
