IPC WP-006

The IPC Solder Products Value Council White Paper, "Round Robin Testing and Analysis, Lead Free Alloys - Tin, Silver and Cooper" (IPC-SPVC-WP-006), summarizes a round robin test program on the assembly properties of three lead free solder alloys. Melt characterization, wetting balance responses and solder spread tests were performed by IPC-SPVC members on the three tin-silver-cooper alloys in the following percentages respectively: 96.5/ 3.0/ 0.5; 95.5/ 3.8/ 0.7; and 95.5/ 4.0/ 0.5. The 19-page white paper includes examples of statistical analysis, data analysis of the tests, data tables of testing participants and a reproduction of IPC test methods used.
