fine-pitch land grid array FLGA package with metal lands on one side of a substrate 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 part, 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 60191-6-12 © IEC:2011 –6– IEC 1163/11 Figure – 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 press machine IEC 1164/11 Figure – Rectangle-type FLGA 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 numbered from left to right starting with 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 Nominal package dimension A nominal package dimension is defined as “the package width (E) × length (D)”, which is expressed in the tenths place in millimeter BS EN 60191-6-12:2011 60191-6-12 © IEC:2011 –7– Outline drawings and

than a quarter of the body size True positional tolerances of terminals, x1 and x2 , are applied to all terminals The terminal diameter b is the maximum diameter of individual balls as measured in the
