Shock and Vibration
The mounting method you use, components you select, and assembly techniques you use
influence the ability of the system to resist fretting corrosion and other damage caused by
exposure to shock and vibration. Consider the following factors when designing your
sbRIO-9637 system to account for shock and vibration:
• Directly mounting the thermal solution to a rigid surface provides the best performance.
If this method is not feasible for your design, minimize the amount of extra mass that
only the sbRIO-9637 supports, such as a heat sink or other thermal solution, that is
fastened to the four standoffs. If you require substantial thermal solutions, provide
additional structural support.
• NI recommends that you use connectors that provide the following benefits:
– Positive locking
– Provisions for strain relief
– Substantial gold plating on pins
• The sbRIO-9637 has been tested to industry specifications for rugged environments.
• NI offers a variety of cable assemblies and other connectivity accessories to complete
your system design. Typically, these accessories include the best available designs,
materials, and plating to maximize performance and longevity in rugged environments.
