Section: Webinars

This project was organized to assess the process parameters for assembling Pb-free SnAgCu BGAs under the temperature constraints of a conventional tin-lead (SnPb) assembly process.  The objective was to understand the reliability of the resulting mixed-alloy solder joints.  The first phase of the project characterized the peak temperature effects on Pb-free BGAs in SnPb paste.  The second phase studied the reliability of Pb-free BGAs processed within the temperature constraints of SnPb assembly conditions.
