To maximize the efficiency of this package for application on a single layer or multilayer PCB, certain guidelines
must be followed when laying out this part on the PCB.
The following information is to be used as a guideline only.
For further information, see the PowerPAD concept implementation document.
In a multilayer board application, the thermal vias are the primary method of heat transfer from the package
thermal pad to the internal ground plane (see Figure 4 and Figure 5).
The efficiency of this method depends on several factors: die area, number of thermal vias, thickness of copper,
etc. (see the PowerPAD Thermally Enhanced Package Technical Brief, literature number SLMA002).
Figure 4. Package and PCB Land Configuration for a Multilayer PCB
Figure 5. Multilayer Board (Side View)
In a single-layer board application, the thermal pad is attached to a heat spreader (copper areas) by a low
thermal-impedance attachment method (solder paste or thermal conductive epoxy). With either method, it is
advisable to use as many copper traces as possible to dissipate the heat.
