Safety Precautions
Precautions for Correct Use
•For Operating
•For Mounting
(1) Do not apply excessive force to the contacts. Doing so may cause
the contacts to deform or the contact plating to peel, resulting in
contact failure.
(2) Do not touch contacts directly with your fingers or other parts of
your body. Doing so may cause the contacts to deform, resulting
in contact failure.
(1) Use reflow conditions that are within the ranges specified by
OMRON. However, reflow conditions depend on the type of
solder, manufacturer, quantity, board size, and other mounting
materials and conditions. Always confirm mounting conditions
before actual application.
(2) Do not mount the Connectors with manual soldering. If the end of
the soldering iron comes into contact with the Connector,
deformation may result.
(3) Do not perform the following operations during mounting. Doing so
may damage the Connector, resulting in contact failure or
mounting failure.
•Stack boards to which the Connectors are mounted.
•Touch the contact section or hold-downs with tweezers or other
objects.
•Apply outward force on the contact sections.
•For Designing
(1) Design the case so that the contacts are not subject to a load from
the top when the battery is inserted. Not doing so may cause the
contacts to deform, resulting in contact failure.
(2) Use the following specifications for the plating on the battery pad
surface: nickel base with gold plating of a thickness of 1.5 μm or
greater.
(3) Use a metal mask thickness of between 0.12 to 0.15 mm. The
recommended metal mask opening ratio is 90% of the processing
dimensions on the PCB in the external dimensions diagram.
(4) Design the case so that the contacts are located as shown in the
outline drawing when the battery is mated.
