Values in inches are converted from mm and rounded to 4 decimal digits. 2. LBGA stands for Low profile Ball Grid Array. – Low profile: The total profile height (Dim A) is measured from the seating plane to the top of the component – The maximum total package height is calculated by the following methodology: A2 (Typ) + A1 (Typ) + (A12 + A32 + A42 tolerance values) – Low profile: 1.20 mm < A < 1.70 mm 3. The typical ball diameter before mounting is 0.60mm. 4. 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. 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. Table 54. LBGA208 mechanical data (continued) Symbol mm inches(1) Notes Min Typ Max Min Typ Max |
