18.2 Standoffs and Screw Hardware
All of the SMARC Evaluation Carrier mezzanine sites have captive, threaded standoffs of the correct height installed. All
of these sites use PEM SMTSO surface mount standoffs with M2.5 threads. The standoffs have very good pull-strength
and may be used to secure the mezzanine boards.
18.3 Shock and Vibration
The SMARC Evaluation Carrier is not designed to any particular shock and vibration standard.
It does have 10 mounting holes that are distributed fairly evenly across the 210mm x 200mm board area, and the
Evaluation Carrier PCB is stiff as the PCB is 2mm thick, so it should be possible to create a robust system from it.
However, its primary purposes are as an evaluation and development tool, and it is not intended for use in high shock
and vibration environments.
18.4 Thermal Environment
All components, save a very limited number of exceptions, on the SMARC Evaluation Carrier are selected as Industrial
Temperature range (-40 °C to +85 °C) parts.
The SMARC Carrier is validated over the -40 °C to +70 °C range.
The overall system performance depends of course on the combination of sub-systems. Some SMARC Modules are
available in the Industrial Temperature range. Others are Commercial Temp range parts. Similar considerations apply to
any of the Mezzanine peripherals that are used with the Evaluation Carrier.
18.5 Humidity
Operating: 10% to 90% RH (non-condensing).
Non-operating: 5% to 95% RH (non-condensing).
18.6 RoHS Compliance
The SMARC Evaluation Carrier is compliant to the 2002/95/EC RoHS directive.
