Mechanical
The VPK180 evaluation board includes a mechanical stiffener to help ensure success with the board under normal lab conditions and use. While it is 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 Standard ESD 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 seven screws and loosely tighten. Finally, in a left to right or right to left pattern, tighten all nine screws to 4.5 in-lbs.
