CASE 776–02
NOTES:
1. DATUMS –L–, –M–, AND –N– DETERMINED WHERE TOP OF LEAD SHOULDER
EXITS PLASTIC BODY AT MOLD PARTING LINE.
2. DIMENSION G1, TRUE POSITION TO BE MEASURED AT DATUM –T–, SEATING
PLANE.
3. DIMENSIONS R AND U DO NOT INCLUDE MOLD FLASH. ALLOWABLE MOLD
FLASH IS 0.010 (0.250) PER SIDE.
4. DIMENSIONING AND TOLERANCING PER ANSI Y14.5M, 1982.
5. CONTROLLING DIMENSION: INCH.
6. THE PACKAGE TOP MAY BE SMALLER THAN THE PACKAGE BOTTOM BY UP
TO 0.012 (0.300). DIMENSIONS R AND U 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.
7. DIMENSION H DOES NOT INCLUDE DAMBAR PROTRUSION OR INTRUSION.
THE DAMBAR PROTRUSION(S) SHALL NOT CAUSE THE H DIMENSION TO BE
GREATER THAN 0.037 (0.940). THE DAMBAR INTRUSION(S) SHALL NOT
CAUSE THE H DIMENSION TO BE SMALLER THAN 0.025 (0.635).
