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
