9-channel SD memory card interface filter with ESD protection
9. Design and assembly recommendations
9.1 PCB design guidelines
For optimum performance it is recommended to use a Non-Solder Mask PCB Design
(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.
For this case, refer to
Table 8
for the recommended PCB design parameters.
