Assemble the jack screw.
The bottom piece of the jack screw is pre-mounted on the BRK1900 (peripheral) board.
Screw the top piece of the jack screw into the bottom piece of the jack screw until finger-tight.
Align the connectors.
Align the mezzanine connectors on the module board with the mating connectors on the breakout board.
Do not press them together yet.
Insert the screw and washer into the jack screw and tighten until finger-tight.
Secure all hardware.
Use a screwdriver to tighten the screws in a “round-robin” manner: sequentially tighten each screw by approximately one-half turn until all screws are tight. Do not over-tighten.
Loosen and remove all screws and washers.
Separate the boards
Use a hex wrench to extend the jack screws in a “round-robin” manner: sequentially loosen each standoff top piece by approximately one-half turn until the mezzanine connectors have separated.
