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

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

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

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

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

Interesting... We had visitors from (maybe out of space) that claims that the fumes!!! from whithin the reflow leadead solder process in an oven can get caught inside the oven during time and later on when we fire up the beast to the lead free temp-p

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 might have misunderstood your question but as far as I am aware a Leadfree Reflow Oven is exactly the same other than the adjustments required for your Profile... aj...

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
