New lead-free solders must have the appropriate melting temperatures and freezing ranges, in order to be compatible with existing equipment and components. A thermodynamic database can be used to predict these properties and also show the effects of non-equilibrium solidification. The results from these predictions can be used to eliminate candidate solder alloys for which the calculation revealed unsuitable freezing temperature and range from further testing. This resource contains a collection of calculated binary and ternary systems that are relevant to solders. The thermodynamic descriptions of these systems are compiled in database files which can be downloaded
