The research will cover assembly performance and basic materials properties, such as wetting, phase structure of the materials, thermal shock performance, long-term thermal cycling behavior and solder joint reliability.
�This research on lead-free solder will provide significant value to the electronics industry, as companies transition to lead-free assemblies to meet emerging global requirements that ban lead from electronics products,� explained Peter Palmer, vice president of Global Marketing at Cookson Electronic Materials and chairman of the IPC SPVC. �I am delighted with the comprehensive scope of the research, the dedication of the members of the council and the contribution of our research partners. This program is a great example of what an industry can do when they work together.�
The IPC SPVC, which is funding the study, is made up of leading international solder materials suppliers, including AIM; Cookson Electronics Assembly Materials Group; Amtech, Inc.; Avantec Performance Chemicals, Electronic Business Unit; EFD, Inc.; Henkel Loctite; Indium Corporation; Kester Northrop Grumman; Nihon Superior Company Ltd.; P. Kay Metal Supply Inc.; Qualitek Group of Companies; Senju Metal Industry and Thai Solder Industry Corporation.
The IPC SPVC Lead-Free Subcommittee, chaired by Karl Seelig, AIM, Inc., is organizing the test program. The study is also supported by two of the leading electronics manufacturing services companies, Flextronics and Solectron Corporation, who will provide test vehicle assembly. In addition, the NAVSEA Crane Division, Naval Surface Warfare Center will provide the long-term reliability testing and Engent will evaluate the solder prior to assembly.
A complete data analysis and white paper summary of the work is scheduled for completion in the first quarter of 2004, upon completion of the testing.
Furthermore, IPC announced that, once it is published, the data will not only be used by IPC�s Technical Committees, but it will also influence the standards of the International Electrotechnical Commission (IEC) Technical Committee TC 91��Electronics Assembly Technology.�
Dieter Bergman, IPC�s director of technology transfer, Dr. Greg Munie, Kester Solder, and Dr. Alan Rae, Cookson Electronics, will act as technical liaisons between IPC and IEC in the sharing of the technical information.
