Notes:
1. Dimension D1 and E1 do not include mold protrusion.
Allowable protrusion is 0.25mm per side. Dimension D1
and E1 do not include mold mismatch and are determined
a datum plane –H– .
2. Dimension b does not include dambar protrusion.
Allowable dambar protrusion will not cause the lead width
to exceed the maximum b dimension by more than
0.08mm. Dambar cannot be located on the lower radius of
the lead foot.
