2. Place the carrier card on the press-fit jig and insert the JSOM standoff. Close the press-fit jig
cover.
3. Insert the connector top tool in the press-fit cover and place it on top of the two JSOMs
located beside connector JA2. Press the JSOM standoff into the card following the
parameters listed in
Table 17: JSOM Standoff Press-fit Parameters
. Remove the top tool once
the press-fit is completed.

Board to Board Assembly Guidelines
Samtec jack screw standoff, part number JSOM-0515-01, is recommended by Samtec to be used
as mechanical support in its board-to-board (B2B) connector assembly. This JSOM type standoff
protects connectors from over mechanical stresses during mating and de-mating assembly.
