PCB Layout Recommendations
package is included on the Package Dimension page. It is
critical that the exposed metal pad is properly soldered to
the ground copper area and then connected to a ground
plane through thermal vias. The maximum recommended
thermal via diameter is 12 mils (0.305 mm). Limited by the
size of the pad, six thermal vias should allow for proper
thermal regulation without sacrificing too much copper
area within the pad. The copper pad is the primary heatsink
and should be connected to as much top layer metal as
possible to minimize the thermal impedance. Figure 21
illustrates graphically the recommended connection for the
exposed pad with vias.
