Standoffs also provide necessary
mechanical support in order to
prevent mechanical stresses from
damaging the module during shock / vibration.
Standoff sitting on pad / plated through-hole
that is connected to the chassis
ground plane within the PCB.
Female-female standoffs are
s
hown, however standoffs are
also available in male-female versions.
