07-4. Detailed precautions for solder rework

(1) Flux-applying tool

To prevent solder creeping to a contact section,
we recommend the use of a brush pen that can
apply an appropriate amount of flux.
(e.g., BON-102F, Japan Bonkote)

(2) Selection of soldering iron

For FPC connector with 0.3-mm pitch, we recommend:

- An iron tip with a

retractable-knife shape

Ex. Japan Bonkote

- With a temperature sensor on the iron tip
- Temperature-controllable iron tip

It is also necessary to check that there are no differences between the indicated
temperature and the actual temperature of the iron tip.

The following temperatures are recommended for iron tips:
- Eutectic solder: 300–

320˚C

- Lead-free solder of three elements: 340–

360˚C

Conventional tool: Dropper

Recommended: Brush pen
