width to exceed the maximum b dimension by more
than 0.08 mm. Dambar cannot be located on the lower
radius or the foot. Minimum space between protrusion
and an adjacent lead is 0.07 mm for 0.4 mm and 0.5
mm pitch packages.
8. Exact shape of each corner is optional.
9. These dimensions apply to the flat section of the lead
