recommended to not remove this stiffener, it is understood that it might be
necessary to remove it for continued evaluation.
The mechanical stiffener screw torque is 4.5 in-lbs. When attaching or removing the
mechanical stiffener, ensure proper ESD precautions are taken. See
Measures for suggestions on best practices.
Removing the Stiffener
With power and other cabling unplugged, carefully unscrew the eleven 4-40
screws in any order. Care needs to be taken with the cooling solution as the
board is manipulated due to potential excessive forces.
Attaching the Stiffener
With power and other cabling unplugged, carefully align the PCBA standoff
holes to the sheet metal tray (stiffener) standoffs. Next, it is suggested to
insert two screws in opposite corners of the board/tray combination. Loosely
tighten the screws to aid in alignment. Add the remaining nine screws and
loosely tighten. Finally, in a left to right or right to left pattern, tighten all eleven
screws to 4.5 in-lbs.
