sUsage 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±10 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”.
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.
sRemoval 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.
* The tab should return to its original position after the contact is removed.
* The tab must be in its original position before inserting the new socket contact.
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.
