As converting our boards to lead-free finish (Immersion White Tin) we decided to change de mask color from green to blue. We thought this would be a good idea to spread the idea so we could easily recognize the type of solder application related to this board. We also printed Sb on the board part number as to identifies what kind of lead-free finish. Could that also be a good idea for componentsthat are lead-free with some markings of what kind of alloy leads are covered (ex. Sn, SnCu). As I understand, there are no great problems with lead-free alloys as far as compatibility. Only lead finishes and lead-free alloys seem to be a problem.
