EUREKA Project LEADFREE

Summary form only given. EUREKA is a European initiative to co-ordinate research within Europe. In this network LEADFREE has been started in co-operation with several partners from industry and research to evaluate the properties of lead free solder alloys and the reliability of solder joints made of lead free solder. In the project comparative reliability data between various lead free alloys on the basis of slow thermal cycles will be worked out. Production parameters for selected solder alloys are evaluated and implemented in the production of the industrial partners. Long term thermal cycling on test-boards will be performed. The deformation- and degradation-behaviour of selected lead free solder alloys will be modelled. Recommendations for the design of accelerated thermal cycling tests will be worked out.
