3. Dimension D does not include mold flash protrusions or gate burrs. Mold flash, protrusions or
gate burrs shall not exceed 0.15 mm (0.006 in) per end. Dimension E1 does not include
interlead flash or protrusion. Interlead flash or protrusion shall not exceed 0.25mm per side. D
and E1 dimensions are determined at datum H.
4. The package top may be smaller than the package bottom. Dimensions D and E1 are
determined at the outermost extremes of the plastic body exclusive of mold flash, tie bar burrs,
gate burrs and interlead flash, but including any mismatch between the top and bottom of the
plastic body.
5. Datums A & B to be determined at datum H.
6. N is the number of terminal positions. (N=16)
7. The dimensions apply to the flat section of the lead between 0.10 to 0.25mm from the lead tip.
8. Dimension “b” does not include dambar protrusion. Allowable dambar protrusion shall be
0.10mm total in excess of the “b” dimension at maximum material condition. The dambar cannot
be located on the lower radius of the foot.
