NOTES

1. Cleaning

This relay is not the sealed type, so it can-

not 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

212

within 2 mins

(PC board solder surface)

* Soldering: 260

500

within 5 s

2) Hand soldering

* Iron tip temperature: 280 to 300

536

to 571

* Soldering iron: 30 to 60W

* Soldering time: Within 3 s

For Cautions for Use, see Relay Technical Information (Page 11 to 39).
