16. Mounting
16.1 PCB design guidelines
It is recommended, for optimum performance, to use a Non-Solder Mask Defined
(NSMD), also known as a copper-defined design, incorporating laser-drilled micro-vias
connecting the ground pads to a buried ground-plane layer. This results in the lowest
possible ground inductance and provides the best high frequency and ESD performance.
Refer to Table 18 for the recommended PCB design parameters.
