[2]
To achieve optimum performance it is recommended to use a Non-Solder Mask
Design (NSMD) Printed-Circuit Board (PCB) design, 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
PCB design parameters.
