PACKAGE INTEGRITY/MOUNTING GUIDELINES
The AD12400 is a printed circuit board (PCB) based module
designed to provide mechanical stability and support the
intricate channel-to-channel matching necessary to achieve
high dynamic range performance. The module should be
secured to the motherboard using 2-56 nuts (washer use is
optional). The torque on the nuts should not exceed 32 inch
ounces.
The SMA edge connectors (AIN, ENC/ENC) are surface
mounted to the board in order to achieve minimum height of
the module. When attaching and routing the cables, one must
ensure they are stress-relieved and do not apply stress to the
SMA connector/board. The presence of stress on the cables may
degrade electrical performance and mechanical integrity of the
module. In addition to the routing precautions, the smallest
torque necessary to achieve consistent performance should be
used to secure the system cable to the AD12400’s SMA
connectors. In no case should the torque exceed 5 inch pounds.
Any disturbances to the AD12400 structure, including
removing the covers or mounting screws, will invalidate the
calibration and result in degraded performance. Refer to the
Outline Dimensions section for mounting stud dimensions.
Refer also to Figure 37 for PCB interface locations. Mounting
stud length will typically accommodate a PCB thickness of
0.093". Consult the factory if board thickness requirements
exceed this dimension.
