Although no-clean practices have altered printed board manufacturing processes, reliability expert Cheryl Tulkoff warns that, “Everyone should be thinking about cleaning and contamination issues.” Tulkoff, DfR Solutions, is among the experts who will address the wide range of factors impacting reliability at the IPC Conference on Solder and Reliability: Materials, Processes and Tests, November 13–14 in Costa Mesa, Calif.
In the drive toward array packaging and other bottom termination configurations Tulkoff says, Manufacturing processes can be optimized to minimize problems and testing can help detect boards with defects, but the best way to avoid problems is to think about potential reliability issues in the design phase. She adds, “In the design phase, you can create alleys or pathways in the solder mask, and in stencil designs to allow the materials to get away from the chips. Another essential step – before manufacturing even begins – is to start with clean bare boards.”
In addition to presentations on cleaning and contamination issues, the conference agenda will cover a variety of topics, including: strategic reliability considerations, properties of solder alloys, defects like pad cratering, risk mitigation processes and data analysis. Speakers will also provide updates on: adhesives and packaging, key challenges in assembly and attachment, changes in component manufacturing as companies move from gold to copper wire bonding for cost savings and the proliferation of lead-free alloys.
IPC Conference on Solder and Reliability follows the 7th International Symposium on Tin Whiskers, which runs Tuesday, November 12 through noon on Wednesday, November 13. These back-to-back events provide an ideal setting for a comprehensive update on reliability issues, with access to people who are experts in their fields.
