iNEMI Mobilizes for Tin/lead BGAs
November 9, 2006 |Estimated reading time: 1 minute
HERNDON, Va. The International Electronics Manufacturing Initiative (iNEMI) consortium organized "Sn/Pb BGA Availability Task Group" to address the needs of OEMs exempt or out-of-scope from the RoHS Directive. The task group scheduled a workshop to bring together OEMs with the BGA supply base on January 24, 2007, in or near San Jose, Calif.
For high-reliability and long-service-life products, tin/lead solders and materials are a clear choice, said Ken Stuchlik, SCN processor and I/O technical manager for Lucent Technologies, and co-chair of the iNEMI task group. While Stuchlik believes that all electronic products will eventually become lead-free, he asserted the necessity of tin/lead products in the interim, citing that lead-free reliability is uncertain and unpredictable. In the supply-chain transition to meet high-volume, lead-free orders, scarce availability of tin/lead components coupled with a prevalence of lead-free connection finishes affects compatibility in tin/lead manufacturing processes. This problem is most notable with BGAs, according to the group.
Task group efforts will focus on influencing the BGA component supply base (IC as well as packaging firms) to support tin/lead-compatible BGAs, assist with questions of long-term reliability, and/or develop other solutions to address concerns. The group plans to develop a list of critical BGA component families, estimate total available market (TAM) for these devices in tin/lead assembly versions, provide a general business case based on TAM, and work to find alternatives.
The January workshop will review the business case for the ongoing availability of tin/lead-compatible BGAs, and likely scenarios for meeting supply-demand over the next several years. This collaboration may provide insight into company strategies by combining interested parties, said Jun Ma, director, supplier engineering at Sun Microsystems, and co-chair of the task group.
