I need to do this because Leaded [ROHS5/6] device I was using is obsolete and Non-leaded[ROHS6/6] drop-in-replacement part is available now. One way out I am thinking is, not sure if it is correct or not. - Can we use non-leaded solder paste/solder cream for soldering this Non-leaded[ROHS6/6] on board? Because of lower temp. [240 Deg.C] this Non-leaded[ROHS6/6] device balls may not melt but non-leaded solder paste will help. I am sorry if you feel this query is not relevant in this forum.
