2.2 Minimal design
This is a minimal design for a NEO-M8L GNSS receiver.

2.3 Layout: Footprint and paste mask
Figure 5 describes the footprint and provides recommendations for the paste mask for NEO-M8L
modules. These are recommendations only and not specifications. Note that the copper and solder
masks have the same size and position.
To improve the wetting of the half vias, reduce the amount of solder paste under the module and
increase the volume outside of the module by defining the dimensions of the paste mask to form a T-
shape (or equivalent) extending beyond the copper mask. For the stencil thickness, see section 4.2.
☞ Consider the paste mask outline when defining the minimal distance to the next component. The
exact geometry, distances, stencil thicknesses and solder paste volumes must be adapted to the
specific production processes (e.g. soldering) of the customer.
