Allowable mold protrusion is 0.010 inch per side. Dimensions
Dimensioning and tolerancing conform to ASME Y14,5M-1994.
To be measured at seating plan - C - contact point.
Dimensions “D1” and “E1” do not include mold protrusion.
“D” and “E” include mold mismatch and determined at the
parting line; that is “D1” and “E1” are measured at the extreme
material condition at the upper or lower parting line.
Exact shape of this feature is optional.
Details of pin 1 identifier are optional but must be located
within the zone indicated.
Sum of DAM bar protrusions to be 0.007 max per lead.
Controlling dimension : Inch.
