DF24 Series

■Usage recommendations and Precautions

1. Recommended

temperature profile

(Including Lead-free solder)

2.Recommended manual soldering

3.Recommended screen thickness and

opening area ratio (Pattern area ratio)

4. Board warpage

5. Cleaning conditions

6. Wire preparation and

contact crimping

7. Precautions

Manual soldering: 300±10ç for 3 seconds

Thickness: 0.12mm

Opening area ratio: 80%

Maximum of 0.03mm at the connector center, with both ends of the connector as reference points.

Refer to “Nylon Connector Use Handbook”.

Refer to “Nylon Connector Use Handbook”.

The crimp contacts are of a very small form and because of this, crimping should be performed carefully

based on the content of the Crimping Conditions Table and the Crimping Quality Standards Manual.

■Removal of the inserted socket contacts

* Using the socket contact extraction tool (DF-C-PO(B) ) carefully lift the contact retention tab on the

insulator housing, as shown on the Fig.1 and pull-out the wire.

* Lift the tab ONLY enough to remove the contact. Exercise caution NOT to deflect too much.

Note 1: Up to 2 cycles of Reflow soldering are possible under the same conditions, providing that

there is a return to normal temperature between the first and second cycle.

Note 2: The temperature profile indicates the board surface at the point of contacts with the

connector terminals.
