2. The top package body size may be smaller than the bottom package size by as much as 0.15 mm.
3. Dimensions D1 and E1 do not include mold protrusions. Allowable protrusion is 0.25 mm per side. D1 and E1 are maximum plastic
4. Dimension b does not include Dambar protrusion. Allowable Dambar protrusion shall not cause the lead width to exceed the maximum b
body size dimensions including mold mismatch.
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.
