Handling the PC board
Storage of connectors
1) Finish reworking in one operation.
2) In case of soldering rework of bridges. Do not use
supplementary solder ﬂux. Doing so may cause contact
problems by ﬂux.
3) Keep the soldering iron tip temperature below the
temperature given in Table A.
1) Make sure not to drop or allow parts to fall from work bench.
2) Excessive force applied to the terminals could cause warping,
come out, or weaken the adhesive strength of the solder. Handle
3) Do not insert or remove the connector when it is not soldered.
Forcibly applied external pressure on the terminals can weaken
the adherence of the terminals to the molded part or cause the
terminals to lose their evenness.
This product is designed with ease of handling. However, in
order to prevent the deformation or damage of contacts and
molding, take care and do not mate the connectors as shown
Strongly pressed and
Press-ﬁtting while the mating
inlets of the socket and
header are not matched.
There is no need to clean this product.
If cleaning it, pay attention to the following points to prevent the
negative effect to the product.
1) Keep the cleaning solvent clean and prevent the connector
contacts from contamination.
2) Some cleaning solvents are strong and they may dissolve the
molded part and characters, so pure water passed liquid solvent
Handling the PC board after mounting the connector
When cutting or bending the PC board after mounting the
connector, be careful that the soldered sections are subjected to
The soldered areas should not be subjected to force.
1) To prevent problems from voids or air pockets due to heat of
reﬂow soldering, avoid storing the connectors in areas of high
2) Depending on the connector type, the color of the connector
may vary from connector to connector depending on when it is
produced. Some connectors may change color slightly if
subjected to ultraviolet rays during storage. This is normal and
will not affect the operation of the connector.
3) When storing the connectors with the PC boards assembled
and components already set, be careful not to stack them up so
the connectors are subjected to excessive forces.
4) Avoid storing the connectors in locations with excessive dust.
The dust may accumulate and cause improper connections at
the contact surfaces.
1) Do not remove or insert the electriﬁed connector (in the state
of carrying current or applying voltage).
2) Dropping of the products or rough mishandling may bend or
damage the terminals and possibly hinder proper reﬂow
3) Before soldering, try not to insert or remove the connector
more than absolutely necessary.
4) When coating the PC board after soldering the connector to
prevent the deterioration of insulation, perform the coating in
such a way so that the coating does not get on the connector.
5) There may be variations in the colors of products from
different production lots. This is normal.
6) The connectors are not meant to be used for switching.
7) Product failures due to condensation are not covered by
