Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reflow

solder processes. KEMET only recommends wave soldering of EIA 0603, 0805 and 1206 case sizes.

Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reflow solder processes.

Density Level C: For high component density product applications. Before adapting the minimum land pattern variations the user should perform

qualification testing based on the conditions outlined in IPC Standard 7351 (IPC–7351).
