1. Solder Please use the flux-resistant type or sealed type in the case of automatic soldering.
Please use the sealed type for cleaning. Also, use the alcohol type for cleaning liquid and avoid
ultrasonic cleaning.
2. Cleaning
When cleaning a printed circuit board after soldering, we recommend using alcohol-type cleaning
liquid. Please avoid ultrasonic cleaning. The ultrasonic energy may cause breaking of coil and
sticking of contacts.

3. Terminal clinch Avoid bending terminals for the relay of print circuit board since it may cause malfunction.
1.Transportation Relay’s functional damage may occur if strong vibration, shock or heavy weight is applied to a relay
during transportation of a device in which a relay is installed. Therefore, please pack them in a way,
using shock-absorbing material, so that the allowable range for vibration and shock is not exceeded.
17. Storage,
transportation
2. Storage If the relay is stored for extended periods of time (including transportation period) at high
temperatures or high humidity levels or in atmospheres with organic gas or sulfide gas, sulfide film or
oxide film may be formed on surface of the contacts, which may cause contact instability, contact
failure and functional failure. Please check the atmosphere in which the units are to be stored and
transported.
Some types of relays are supplied with tube packaging. If you remove some relays from the tube, be
sure to slide a stop plug into one end of a tube to hold the remaining relays firmly and avoid rattling of
relay inside the tube. Note that rattling may cause a damage on appearance and/or performance.

1. Tube packing
Do not use the relays if they were dropped or fallen down in a tube packing condition because there
is a risk of characteristic failure.
