Soldering Guidelines For The "RJ-B" Relay Series
We use only precision equipment and proven testing methods,
specializing in metal to ceramic seals.
The ceramic body assemblies of the "RJ-B" relays are brazed @ 810°C
in hydrogen atmosphere, therefore it should not be a problem to solder
any terminal leads using solder wire appropriate for electrical applications.
Both the switch and coil terminals are coated with 60/40 soft solder.
Recommended solder compositions:
TIN/LEAD 50/50, 40/60, 60/40
The tin/lead solder group constitutes the largest portion of solders
in use. With the exceptions, the tin/lead solders can be used to solder
copper, most copper alloys, lead, high nickel alloys and steel.
The tin/antimonial solder is useful for applications where moderately
elevated temperature is a factor. It has a high electrical conductivity
and is recommended where lead contamination must be avoided. The tin/antimony
solders are not recommended for use on brass.
||Melting Temperature (°C)
||High melting point Lead-free
||Silver plated surfaces
The use of acid flux/core is not recommended for this application since
its residues could damage the relay surface.
