’D’ and ’E’ do not include mold flash or protrusions. Mold flash or protrusions shall not exceed 0,15 mm per side
Each lead centerline shall be located within ± 0,10 mm of its exact true position.
Leads shall be coplanar within 0,08 mm at the seating plane.
Dimension ’B’ does not include dambar protrusion. The dambar protrusion(s) shall not cause the lead width
to exceed ’B’ maximum by more than 0,08 mm.
Dimension applies to the flat section of the lead between 0,10 mm and 0,25 mm from the lead tip.
’A1’ is defined as the distance from the seating plane to the lowest point of the package body (base plane).
