5.0 LAND PATTERN DIMENSIONS
Figure 3 provides the land pattern dimensions for SQFP (Rect-
angular) components. These numbers represent industry con-
sensus on the best dimensions based on empirical knowledge
of fabricated land patterns.
In the table, the dimensions shown are at maximum material
condition (MMC). The least material condition (LMC) should
not exceed the fabrication (F) allowance shown on page 6.
The LMC and the MMC provide the limits for each dimension.
The dotted line in Figure 3 shows the grid placement court-
yard 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.
