Hand Assembly
Pads located on the bottom of the
Castellations
module are the primary mount-
ing surface. Since these pads are
inaccessible during mounting,
castellations that run up the side
of the module have been provided
to facilitate solder wicking to the
module’s underside. This allows
for very quick hand soldering
for prototyping and small volume

production.
If the recommended pad guidelines have been followed, the pads will
protrude slightly past the edge of the module. Use a fine soldering tip to
heat the board pad and the castellation, then introduce solder to the pad
at the module’s edge. The solder will wick underneath the module,
providing reliable attachment. Tack one module corner first and then work
around the device, taking care not to exceed the times listed below.
