Landing pattern recommendation

For the design of the landing pattern, the following dimensioning is recommended:

Figure 19: Recommended landing pattern (top view); dimensions are in mm

Note: red areas demark exposed PCB metal pads.

•

In case of a solder mask defined (SMD) PCB process, the land dimensions should be defined

by solder mask openings. The underlying metal pads are larger than these openings.

•

In case of a non solder mask defined (NSMD) PCB process, the land dimensions should be

defined in the metal layer. The mask openings are larger than the these metal pads.
