Dimension D1 and E1 do not include mold protrusion. Allowable protrusion is 0.25mm per side. Dimensions D1 and E1 do include mold mismatch and are determined at datum plane -H-. 2 R1 R2 -HS L GAUGE PLANE 0.25mm 3 DETAIL 1 2. Dimension b does not include dambar protrusion. Allowable dambar protrusion shall be 0.08mm total in excess of the b dimension at maximum material condition. Dambar cannot be located on the lower radius or the lead foot.
