RoHS actually allows for up to 0.1% lead in solder. Unless you are really sloppy at cleaning your tools it would be very unlikely that you would get 0.1% lead into your lead-free process (remember leaded solder is only about 50% lead). Regards, Ber

Can someone advise if there is any risk if we use lead-free alloy wire during rework for Leaded Process?The reason for this proposal is to only have one type of solder wire being used in the line.This will eliminate any possibility of leaded wire bei

On some of our boards we cut the clinched leads with an old Q Corp cutter. Works fine as long as the blade is sharp and the lead isnt bent against the board. Youll know when you go to far on the clinch because the mass lead cutter will begin to start

To anyone with extensive reflow experience, We have an 8-zone reflow intended for reflow soldering of our lead-free models, but sometimes, we use the reflow for soldering of non lead-free. Does it holds true that our lead-free products may be c

I had a vendor change thier lead finish from tin/lead to a SAC305. We built up several assemblies before we realized the change. The reflow process is a standard leaded profile peaking at 220 C. What are the reliablity concerns with mixing the tin/l

Thoughts are: * 215-220 temperature at the leads is not real hot for leaded assembly. * It's peculiar for component leads to dewet. Sometimes non-wetting occurs along the edge of the lead where the lead is not plated. * How do the leads of a removed

My research starts here. I'm just beginning to research the effects of using a leaded part in a no lead process. Before I began, I know there are temperature differences. The part in question has a 260 C spec. Next I would like to find out if any c

When bridging becomes an issue, I like short leads. Lead Free is where I see most bridging occur. Usually when lead length starts to approach lead spacing. As long as the lead is discernible in the joint, it's acceptable. If you are having troubl

Abraham, Lead free components in a leaded process should not be a problem. The problem increases with leaded components in a lead free process. For the most part, the only difference that you will see is in BGA procesing. If a BGA is lead free, the
