Solder Paste Thixotropy Impacts Rheometric Results
Attempts to meet ISO/TS 16949 have informed that a solder paste’s thixotropic history has a major impact on its rheometric characterization repeatability and reproducibility. A novel sample preparation method reduces the thixotropy impact in conjunction with enhanced plate/plate rheometry.
