2.10 Module footprint and paste mask
Figure 63Figure 63 and Table 37Table 37 describe the suggested footprint (i.e. copper mask) and paste
mask layout for SARA-G3 modules: the proposed land pattern layout reflects the modules’ pads layout,
while the proposed stencil apertures layout is slightly different (see the F’’, H’’, I’’, J’’, O’’ parameters
compared to the F’, H’, I’, J’, O’ ones).
The Non Solder Mask Defined (NSMD) pad type is recommended over the Solder Mask Defined (SMD)
pad type, implementing the solder mask opening 50 µm larger per side than the corresponding copper
pad.
The recommended solder paste thickness is 150 µm, according to application production process
requirements.
