Some FMC+ mezzanine cards may present a challenge to unmate from their host. To aid in separation, Samtec has developed the JSOM (Micro Jack Screw Standoff). They act as a traditional standoff when collapsed. An Allen-key unscrews and expands the jack screw, dividing the PCBs in a steady, even motion until the mezzanine is safely separated from its host. The JSOM standoff family includes M2.5, M3, and #4-40 hardware available in 8.5mm and 10mm stack heights.
