Specific notes on thermal characterization conditions:
All boards are 0.062” thick FR4, 3” square, with varying amounts of copper heat spreader, in still air (free convection) conditions. Numerical
values are derived from an axisymmetric finite ? element model where active die area, total die area, flag area, pad area, and board area are
equated to the actual corresponding areas.
1. 1 oz copper, 100 mm 2 (0.155 in 2 ) spreader area (includes exposed pad).
2. 1 oz copper, 645 mm 2 (1 in 2 ) spreader area (includes exposed pad).
3. “board” is defined as center of exposed pad soldered to board; this is the recommended number to be used for thermal calculations, as it
best represents the primary heat flow path and is least sensitive to board and ambient properties.
