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. Table 8. Recommended PCB design parameters Parameter Value or specification PCB pad diameter 200 μm Micro-via diameter 100 μm (0.004 inch) Solder mask aperture diameter 370 μm Copper thickness 20 μm to 40 μm Copper finish AuNi PCB material FR4 9.2 PCB assembly guidelines for Pb-free soldering Table 9.
