Only those products that pass all ETT and
HALT tests are labeled as Extreme Rugged,
giving customers the assurance they need to
put their own products into service. Every test
carried out is documented and recorded in a
database, which is made available to custom-
ers upon request. The same test data is used
for own quality assurance audits.
The inclusion of six-axes vibration testing
is not arbitrary; extreme environments are
typified by exposure to this kind of operat-
ing condition. Because of this, it is standard
for ADLINK rugged components to meet the
main standards imposed by the US Depart-
ment of Defense; MIL-STD-202G Electronic
and Electrical Component Parts Test, and
MIL-STD-810G, which is intended to evaluate
the performance of equipment when exposed
to a lifecycle of environmental stresses. The
former includes an exhaustive list of test con-
ditions, including subjecting components to
50G shocks and 11.95 grams of random vibra-
tion between 100Hz and 1kHz on multiple
axes. In order to meet these stringent require-
ments, ADLINK employs a range of proven
solutions including thicker PCBs and sockets
designed to provide higher levels of reten-
tion, as well as special attention to high-mass
and vulnerable components. This method-
ology extends to the enclosure design, which
delivers a solution that can really be certified
Extreme Rugged.
As well as temperature and vibration, other
aspects of extreme environments can impact
performance and functionality. This extends
beyond humidity to include salt spray, as well
air-borne contaminants. To address these
potential hazards, ADLINK offers conformal
coating which is designed to protect sensitive
components from particulates such as dust, as
well as high levels of moisture which can lead
to short-circuits or corrosion. Conformal coat-
ing offers protection against these hazards, as
well as dendritic growth and general abrasions.
