4. To be determined at the seating plane. The seating plane is def-
ined as the plane of contact that is made when the package lea-
ds are allowed to rest freely on a flat horizontal surface.
5. Dimension D1 and E do not include mold protrusion. Allowable
mold protrusion is 0.15mm (0.0059”) per side.

dambar protrusion shall be 0.08mm (0.0031”) total in excess
of b dimension at max. material condition. Minimum space
between protrusion and an adjacent lead to be 0.07mm
(0.0028”).
