PCB layout example
Figure 19 shows a PCB layout example for the application schematic in Figure 18.
A double-sided FR-4 board of 1.6mm thickness is used. This PCB has ground planes on both
bottom layer and top layer to ensure good grounding of critical component. Additionally,
there are ground areas on the component side of the board to ensure sufficient grounding of
critical components. A large number of via holes connect the top layer ground areas to the
bottom layer ground plane.
