The top package body size may be smaller than the bottom package size by as much as 0.15 mm.
Dimensions D1 and E1 do not include mold protrusions. Allowable protrusion is 0.25 mm per side. D1 and E1 are maximum plastic
body size dimensions, including mold mismatch.
Dimension b does not include Dambar protrusion. Allowable Dambar protrusion shall not cause the lead 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 and 0.5 mm pitch packages.
These dimensions apply to the flat section of the lead between 0.10 mm and 0.25 mm from the lead tip.
A1 is defined as the distance from the seating place to the lowest point on the package body.
