Hello What type of error proofing methods are you guys using to prevent operators from using lead paste on a PB free application?

You're right that us in the automotive market are exempt, but that just delays the inevitable by two or three years. Our customers, especially Japanese, are pushing us to provide Pb free products in the '08/'09 timeframe so that the end customers ge

Today's regular Sn-Pb paste chemistries are designed to run at higher peak temperatures ensuring that your lead-free alloys will coalesce with your regular Sn-Pb solder. That being said, it is do-able to solder both types in one oven. Generally, wit
