NOTES UNLESS OTHERWISE SPECIFIED:
1.
DIMENSIONING AND TOLERANCING PER ASME Y14.5M-1994.
2.
ALL DIMENSIONS ARE IN MILLIMETERS.
3.
BALL POSITION DESIGNATION PER JESD 95-1, SPP-010
(EXCEPT AS NOTED).
4.
e REPRESENTS THE SOLDER BALL GRID PITCH.
5.
SYMBOL "MD" IS THE BALL ROW MATRIX SIZE IN THE "D"
DIRECTION. SYMBOL "ME" IS THE BALL COLUMN MATRIX SIZE
IN THE "E" DIRECTION. N IS THE TOTAL NUMBER OF SOLDER
BALLS.
6
DIMENSION "b" IS MEASURED AT THE MAXIMUM BALL
DIAMETER IN A PLANE PARALLEL TO DATUM Z .
7
SD AND SE ARE MEASURED WITH RESPECT TO DATUMS A
AND B AND DEFINE THE POSITION OF THE CENTER SOLDER
BALL IN THE OUTER ROW. WHEN THERE IS AN ODD NUMBER
OF SOLDER BALLS IN THE OUTER ROW PARALLEL TO THE D
OR E DIMENSION, RESPECTIVELY, SD OR SE = 0.000.
WHEN THERE IS AN EVEN NUMBER OF SOLDER BALLS IN THE
OUTER ROW, SD OR SE = e/2
8.
"+" INDICATES THE THEORETICAL CENTER OF DEPOPULATED
BALLS.
