Are Spansion Non-Pb Flash memory products backward compatible?
Spansion Non-Pb parts are backward compatible. However, in some cases, minor adjustments in the peak reflow temperature may be required to obtain good quality solder joints. Spansion Non-Pb leadframe based packages can be considered as “drop-in replacements,” i.e., can be used in place of their SnPb counterparts with the existing SnPb assembly process. Spansion laminate packages with Non-Pb solder finishes, on the other hand, might require minor adjustments in the reflow profile when being used as replacements to their SnPb counterparts.
