03-5. Detailed precautions for manual soldering
(1)General precautions
- When applying flux, apply it thinly on each foot
pattern using a brush pen as shown on the
previous page.
(Place the connector at a predetermined
position after applying flux.)
- The use of a soldering iron with a retractable-
knife shape tip as shown in the previous page is
also recommended.
- While heating with the soldering iron, it is
recommended to slide the iron tip on the foot
pattern along the terminals without touching them.
- Apply the soldering iron to the foot pattern
to heat it. Complete soldering in 1 or 2 seconds.
Connector's resistance to soldering heat
- 300 C: 5 sec max.
- 350 C: 3 sec max.
- Thin wire solder with
- Final soldering is recommended after provisionally soldering the terminals at
both ends.
- Note that when the soldering iron touches the terminal, wicking or contact
failure may occur.
(2)Detailed precautions on how to apply the iron tip
Place the iron tip on the end of the foot pattern,
and apply heat to melt the solder.
Do not touch and push the terminal with the iron tip,
since the contact may become deformed.
If the iron tip touches and pushes the terminal
end, the contact may also become deformed.
This must also be avoided.
(3)Flux cleaning method
Pay attention to the following points when cleaning flux to prevent contact
failures due to the presence of flux:
- To prevent secondary contamination, clean flux using three-chamber cleaning
equipment because contamination of the cleaning agent can be controlled
