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

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

We have a new program that is going to require us to add many leads to presently leadless parts. It isn't preferred by we are up against the wall. We will be doing mostly passive caps, resistors and diodes and some LCC's as well. Is there any one

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

Are you using lead or lead-free solder? 260C would be good for lead solder but may be a bit low for lead-free. We run our lead-free selective solder pot at 300C although we do not have any pre-heat or top heat, just hot nitrogen blowing around the

Your copper corrosion is not good. It indicates that you have not done a good job in cleaning. [We assume this is a medium green color, not unlike the color of the solder mask on your board, that is almost like a translucent lacquer; rather than th
