Figure 8-3. Simplified Cutaway View of Wettable-Flank QFN Package and Standard QFN Package After

Soldering

Wettable flanks help improve side wetting after soldering which makes QFN packages easier to inspect with

automatic optical inspection (AOI). A wettable flank can be dimpled or step-cut to provide additional surface

area for solder adhesion which assists in reliably creating a side fillet as shown in Figure 8-3. Please see the

mechanical drawing for additional details.
