How does Spansion define backward and forward compatibility between SnPb and Non-Pb reflow processes?
By backward compatibility, we mean to indicate whether a Spansion Non-Pb product is capable of being processed using a SnPb solder process and reflow temperature profile. By forward compatibility, we mean to indicate whether the SnPb product is capable of being processed using a new Non-Pb solder reflow process. Click here for an illustration of these definitions.
