VBK048—48-Ball Fine-Pitch Ball Grid Array (FBGA) 8.15 mm x 6.15 mm
3338 \ 16-038.25b
NOTES:
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 C.
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. NOT USED.
9. "+" INDICATES THE THEORETICAL CENTER OF DEPOPULATED
BALLS.
