The International Electronics Manufacturing Initiative (iNEMI) has outlined a set of recommendations to help electronic manufacturers manage lead-free alloy alternatives. iNEMI’s recommendations support the guidelines developed by the EMS Forum for addressing lead-free alloys.
Although SAC 305/405 have been the most commonly used lead-free alloys to date, iNEMI notes they do not meet all of the industry’s needs for all applications and that new alloy solutions continue to be introduced. iNEMI recommends the following to help manufacturers manage the use of multiple solder alloys:
- Drive convergence of lead-free alloys
- Develop an industry-standard assessment methodology
- Establish performance guidelines
- Update standards
- Identify and differentiate alloys
iNEMI members supporting these recommendations include Agilent, Celestica, Cisco, Delphi, HP, Intel, Jabil, Motorola, Plexus, Sanmina-SCI, Sun and TI.
