Power dissipated by adjacent components
Connect all the ground and power balls to the respective planes with one via per ball. Using fewer vias to
connect the package to the planes reduces the thermal performance. Thinner planes also reduce the thermal
performance. When the clearance between the vias leave the planes virtually disconnected, the thermal
performance is also greatly reduced.
As a general rule, the value obtained on a single-layer board is within the normal range for the tightly
packed printed circuit board. The value obtained on a board with the internal planes is usually within the
normal range if the application board has:
One oz. (35 micron nominal thickness) internal planes
Components are well separated
Overall power dissipation on the board is less than 0.02 W/cm2
The thermal performance of any component depends on the power dissipation of the surrounding
components. In addition, the ambient temperature varies widely within the application. For many natural
convection and especially closed box applications, the board temperature at the perimeter (edge) of the
package is approximately the same as the local air temperature near the device. Specifying the local
ambient conditions explicitly as the board temperature provides a more precise description of the local
ambient conditions that determine the temperature of the device.
