203 / 231 page  DS14539 Rev 1 203/231 STM32H533xx Package information 227 Table 120. WLCSP39 - 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. The profile height, A, is the distance from the seating plane to the highest point on the package. It is measured perpendicular to the seating plane. - - 0.58 - - 0.0228 A1(3) 3. A1 is defined as the distance from the seating plane to the lowest point on the package body. - 0.17 - - 0.0067 - A2 - 0.38 - - 0.0150 - A3 - 0.025 - - 0.0010 - b(4) 4. Dimension b is measured at the maximum diameter of the terminal (ball) in a plane parallel to datum C. 0.23 0.26 0.28 0.0091 0.0102 0.0110 D2.76 BSC(5) 5. BSC stands for BASIC dimensions. It corresponds to the nominal value and has no tolerance. 0.1087 BSC D1 2.000 BSC 0.0787 BSC E 2.78 BSC 0.1094 BSC E1 2.078 BSC 0.0818 BSC e(6) 6. e represents the solder balls grid pitch(es). 0.40 BSC 0.0157 BSC SD(7) 7. Basic dimensions SD and SE are defining the ball matrix position with respect to datums A and B. 0.200 BSC 0.0079 BSC SE(7) 0.346 BSC 0.0136 BSC N39(8) 8. N represents the total number of balls. aaa(9) 9. The tolerance of position that controls the location of the balls within the matrix with respect to each other. 0.02 BSC 0.0008 BSC bbb(9) 0.06 BSC 0.0024 BSC ccc(9) 0.03 BSC 0.0012 BSC ddd(9) 0.015 BSC 0.0006 BSC eee(9) 0.05 BSC 0.0020 BSC |
