Other Notes

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

with care.

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

right.

Tilted mating

Strongly pressed and

twisted

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

is recommended.

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

excessive force.

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

humidity.

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

soldering.

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

warranty.
