Whisker Evaluation

The inspector observes without missing anything! Consistent whisker evaluation is possible from reliability testing to analysis.

While lead-free solder is becoming widespread, whiskers formed from Sn plating or solder joints have a significant impact on the reliability of electronic components. Our company offers a consistent whisker evaluation process from reliability testing to analysis. Inspectors carefully observe which components and pins on the substrate have whiskers. 【Features】 ■ Conduct visual inspections of assembled boards after reliability testing to determine the presence of whiskers. ■ If whiskers are detected during visual inspection, observe and measure them using a digital microscope. ■ For more detailed observation and analysis, perform surface SEM/EDX analysis. ■ If necessary, observations and analyses such as cross-sectional observation (SEM) and crystal orientation analysis (EBSD) are also possible. *For more details, please refer to the PDF document or feel free to contact us.
