Pb free components can be soldered using existing Sn-Pb solder and temperature profiles. This means its Pb free parts can be used on current non-Pb free process without any risk. 2. Non-Pb free components can be soldered using lead-free solders and the appropriate higher temperature profiles. This means its non-Pb free parts can be withstand Pb free temperature profile without problem. I suffered customer's inquirement and they want to make sure that's no problem. Thanks!!

Statement # 2 is false, non-Pb-free parts may not be able to withstand the Pb-free temp profiles, since non-Pb-free parts were qualified using lower peak temps (220-235 C). Rel Eng
