(2)If the board is insufficiently fixed as in the following drawing, the inertial
load applied to the connector may damage it. Pay attention to the following
points.

(3)To facilitate the mating of connectors, we recommend that you pay attention to the
following points when designing the motherboard.
- Provide a reference mark.
- Design a layout that allows easy-checking of the connector mating condition.
Provide a reference
mark using:
- Silk printing
- Pattern (copper foil)

When an impact such as dropping as shown in the
drawing is applied:
(1) If both boards are not sufficiently fixed,
the connector will be damaged due to the
impact applied to the connector.
(2) In particular, if there is no gap between
the casing and sub-board (A<B), the sub-
board side will hit the casing wall first.
This impact may damage the connector.
<Preventive measures>
Securely fix both the motherboard and sub-board.
(1) Fixing motherboard
(Prevents inertial movement by drop impact
by fixing the side with a greater mass.)
(2) Hold down the sub-board to prevent it from
moving using a rubber cushioning material,
etc.
(3) It is safer if board gaps are set to A≥B so as
to prevent shearing damage on deviation of
the board by impact.
