Note
1. DIMENSIONING AND TOLERANCING PER ASME Y14. 5M-1994.
2. ALL DIMENSIONS ARE MILLIMETERS.
3. DIMENSION “D” IS MEASURED AT THE MAXIMUM SOLDER
BALL DIAMETER IN A PLANE PARALLEL TO DATUM C.
4. PRIMARY DATUM C(SEATING PLANE) IS DEFINED BY THE
CROWN OF THE SOLDER BALLS.
5. THIS IS A CONTROLLING DIMENSION.
