NOTES
1. Cleaning
This relay is not the sealed type, so it cannot be immersion cleaned. Be careful that
flux does not overflow onto the PC board
or penetrate inside the relay.
2. Soldering
We recommend the following soldering
conditions.
1) Automatic soldering
* Preheating: 100°C 212°F, within 2 mins
(PC board solder surface)
* Soldering: 260°C 500°F, within 5 s
2) Hand soldering
* Iron tip temperature: 280 to 300°C 536
to 571°F
* Soldering iron: 30 to 60W
* Soldering time: Within 3 s
For Cautions for Use, see Relay Technical Information (Page 11 to 39).
