Leaded components in a no lead process



We will be assembling circuit boards using an RoHS complient assembly line, however our customer does not have an RoHS lead free requirement. Are there any concerns if we use a few leaded components in this process? Are we likely to contaminate our wave solder bath?

Expert Panel Responses

It isn't going to be an issue of lead contamination so much as it might be an issue with reliability. We have seen issues with cracking when the lead gets above .4% in the solder joint. Our suggestion would be to wait to go to lead free until you have all leaded components switched.
