Lead Free Prep. | 11 June, 2008

We are currently completely building lead based assemblies. We are going to start doing our homework based on Management request. I have a pretty strange question that I was asked but really did not have an answer to. Can a Lead-Free assembly have a small percentage of lead in relationship to the weight of the finished product. We were thinking of building an assembly completely lead free with the exception of the wave process.

Our plan was to weigh the assmbly completely populated before and after the wave in order to get a weight of the lead solder that the wave will deposit. Is this a waste of time....

Thanks for the help.

Don't waste your time. Allowable limits are not measured using the % weight of the entire assembly.

Read the RoHS Directives 2005/95/EC what they say about % limits of lead in homogeneous part
