28、in a matrix of at least three rows and three columns on a pitch of 0,8 mm or less, wherein the maximum standoff height is 0,10 mm or less NOTE Terminals may be missing from some row-column intersections. 3.2 flange-type FLGA FLGA with a package outline (length, width) defined by a package flange par
29、t, mostly substrate, extending outward beyond the perimeter of a molded part or of a flip-chip-bonded part NOTE Flange-type FLGA, shown in Figure 1, is generally cut by singulation press, thus resulting in larger dimensional errors than the singulation by dicing saw BS EN 60191-6-12:2011 6 60191-6-1
30、2 IEC:2011 Figure 1 Flange-type FLGA 3.3 rectangle-type FLGA FLGA with a package outline (length, width) defined by a molded part with no extending flange part NOTE Rectangle-type FLGA, shown in Figure 2, is generally cut by dicing, thus resulting in less dimensional errors than the singulation by p
31、ress machine. Figure 2 Rectangle-type FLGA 4 Terminal position numbering When a package is viewed from the terminal side with the index corner in the bottom left corner position, terminal rows are lettered from bottom to top starting with A, then B, C, AA, AB, etc, whereas terminal columns are numbe
32、red from left to right starting with 1. Terminal positions are designated by a row-column grid system and shown as alphanumeric identification, e.g., A1, B1. The letters I, O, Q, S, X and Z shall not be used for naming the terminal rows. 5 Nominal package dimension A nominal package dimension is def
33、ined as “the package width (E) length (D)”, which is expressed in the tenths place in millimeter.
