Recommended IRS Conditions (G6H-2F)
The recommended soldering conditions show the temperature
changes of the PCB surface. The conditions however, differ with
the relay model. Check the relay specifications before soldering
(for details refer to precautions for each model). Do not put the
relay in a cleaning solvent or other cold liquid immediately after
soldering or the seal of the relay may be damaged.

SURFACE MOUNTING
The following tables list the processes required for mounting a relay onto a PCB and the points to be noted in each process.
Process 1: Cream Solder Printing
Do not use a cream solder that contains a flux with a large amount of chlorine or the terminals of the relay may be corroded.
Process 2: Relay Mounting
The holding force of the relay holder must be the same as or more than the minimum holding force value required by the relay.
Process 3: Transportation
The relay may be dismounted by vibration during transportation. To prevent this, it is recommended an adhesive agent be applied to the
relay’s gluing part (protruding part) to tack the relay.

Note: Do not submerge the relay in a solder bath. Doing so will deform the resin causing faulty operation.
