DIMENSIONING AND TOLERANCING PER ASME Y14.5M-1994.
ALL DIMENSIONS ARE IN MILLIMETERS.
BALL POSITION DESIGNATION PER JESD 95-1, SPP-010.
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.
DIMENSION "b" IS MEASURED AT THE MAXIMUM BALL
DIAMETER IN A PLANE PARALLEL TO DATUM Z.
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
"+" IN THE PACKAGE DRAWING INDICATES THE THEORETICAL
CENTER OF DEPOPULATED BALLS.
FOR PACKAGE THICKNESS, "A" IS THE CONTROLLING DIMENSION.
