Note Refer to the device specifications on ni.com/manuals for complete
specifications.
Mounting the Hardware
Before you mount the sbRIO-9687, the thermal kit, sbRIO-9607 controller, and sbRIO-9683 or
sbRIO-9684 GPIC must be mounted to a thermally conductive surface at least 3 mm thick.
The thermally conductive surface acts as a heat spreader for the sbRIO-9607; ensure a good
thermal contact.
Required Tools
The following tools are required for mounting the sbRIO-9687:
• Screwdriver, Phillips #1
• Socket driver, 4.5 mm
2
Measure the local ambient temperature by placing thermocouples on both sides of the PCB, 5 mm
(0.2 in.) from the board surface. Users populating the sbRIO-9687 input termination resistors
should thermally validate that, in the vicinity of the resistors, the local ambient temperature does
not exceed 85 °C and the input termination resistor case temperatures and local PCB surface
temperatures do not exceed 125 °C.
