Why not mixed process (Backward SnPb) ? -----Message d'origine----- De : TechNet [mailto:[log in to unmask]] De la part de Bob Landman Envoyé : vendredi 9 juillet 2010 16:06 À : [log in to unmask] Objet : [TN] Interposer for SAC BGA I have to use a new FPGA from Lattice and they are not offering it in SnPb, only SAC balls. This is a fpBGA 23mm sq with 484 balls in a square array with no special heatsink pads. Environment is -40 to +85C, mild vibration and shock, outside environment in electrical NEMA enclosures. SnPb is a must - I refuse to use lead free process for our products. Two choices: Interposer board (Bill Rollins just told me about this option Reballing Comments please on your preference.
