247 / 260 page  DS12505 Rev 5 247/260 STM32MP157C/F Package information 254 Table 121. TFBGA361 - Mechanical data Symbol millimeters inches(1) 1. Values in inches are converted from mm and rounded to 4 decimal digits. Min Typ Max Min Typ Max A(2) 2. TFBGA stands for Thin Profile Fine Pitch Ball Grid Array. The total profile height (dim A) is measured from the seating plane to the top of the component. - - 1.200 - - 0.0472 A1 0.150 - - 0.0059 - - A2 - 0.810 - - 0.0319 - b(3) 3.

The tolerance of position that controls the location of the pattern of balls with respect to datums A and B. For each ball there is a cylindrical tolerance zone eee perpendicular to datum C and located on true position with respect to datums A and B as defined by e. The axis perpendicular to datum C of each ball must lie within this tolerance zone. - - 0.150 - - 0.0059 fff(5) 5. The tolerance of position that controls the location of the balls within the matrix with respect to each other. For each ball there is a cylindrical tolerance zone fff perpendicular to datum C and located on true position as defined by e. The axis perpendicular to datum C of each ball must lie within this tolerance zone. Each tolerance zone fff in the array is contained entirely in the respective zone eee above The axis of each ball must lie simultaneously in both tolerance zones. - - 0.080 - - 0.0031 |
