De-mating: JSOM Standoff-nut and Jack Screw
Untighten Sequence
There is no special sequence required to unghten the four stando nuts. However, they must
be removed before proceeding to unghten the four jack screws. The order to unghten the four
jack screws is not crical. Once all four of the jack screws are completely unghtened, the SOM
board will pop up and the SOM connectors (male) automacally uncouple from the connectors
(female) on the carrier card. Remove the SOM by carefully holding the card on the two edges.
