Construction
■ SEALING
Unsealed
Relays of this type are intended for manual soldering. No measures
are taken against penetration of flux and cleaning solvent into the
relay. This type of relay cannot be immersion-cleaned.
Semi-Sealed
Special design construction prevents flux from penetrating into the
relay housing, for example, due to capillary action up the terminals
when the relay is soldered onto a PCB. This type of relay also cannot
be immersion-cleaned.

Fully Sealed
Fully sealing prevents not only flux, but also cleaning solvent from
penetrating into the relay housing. Therefore, this type of relay can
be immersion-cleaned. Relays are each tested before being shipped.
The relay is immersed in fluorocarbon solution for 1 minute, at a tem-
perature of 70°C +5°C/-0°C, to see if gases escape from the relay.
The following figure illustrates the test conditions.
