The PBGA Package also dissipates heat through
peripheral ground balls. When a heat sink is
placed on the device, heat is more uniformely
spread throughout the moulding increasing heat
dissipation through the peripheral ground balls.
The more via pads are connected to each ground
ball, the more heat is dissipated . The only limita-
tion is the risk of lossing routing channels.
Figure 6-5 shows a routing with a good trade off
between thermal dissipation and number of rout-
ing channels.
