5.0 LAND PATTERN DIMENSIONS
Figures 2a-2b provide the land pattern dimensions for square
PBGA components. These numbers represent industry con-
sensus on the best dimensions based on empirical knowledge
of fabricated land patterns.
Note: The data supplied in the detail and table reflect a full
matrix. Specific contact and depopulation and pin assignment
must be furnished by the device manufacturer.
The dotted line in Figures 2a-2b shows the grid placement
courtyard which is the area required to place land patterns
and their respective components in adjacent proximity without
interference or shorting. Numbers in the table represent the
number of grid elements (each element is 0.5 by 0.5 mm) in
accordance with the international grid detailed in IEC publica-
tion 97.
