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.

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

First, it's a surprise that your failure analysis lab thought everything was OK with these boards. They look like shit. Second, a few years ago, there was a bunch of complaints about ENIG boards with issues similar to what you're observing. There wa

There are a lot of lead testers out there. Just google it. I personally don't think you will find anything wrong, but for the pleasure of your customers buy one and prove it. I would also check the lead on the squeegees of your stencil printers and t

Guru, you are nothing but a liar, any respectable consulting firm would not use a name as Guru Expert. Also would not change from a contamination thread to all the BS you just threw out trying to impress with your vocabulary. One does not need to qu

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

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

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

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
