Wettable Flanks for non-lead package

Automotive applications requires smaller semiconductor packaging solutions.
Leadless packages such as QFN are desirable as packaging solutions that meet the space-saving and size-limited needs of printed circuit board designs.
For Non-lead packages, the side fillet property of the solder is important in order to pass the automatic visual inspection.
