APPLICATION NOTES
Soldering and Cleaning
of Ceramic Trimmer Capacitors
Soldering temperatures and times are specified in
Notes 3 and 4 above. If using an iron for manual sol-
dering (for prototyping or repairs, for example) use
an appropriate size and temperature so that the
high temperature exposure of the trimmer is less
than 3 seconds.
We strongly recommend the use of water soluble
fluxes for soldering, followed by cleaning in water
containing detergents, and then a clear water
rinse.
Some operations still use Freon or similar fluorinated
or chlorinated hydrocarbon solvents. These solvents
have a tendency to remove the lubricant, which in
turn makes for bumpy adjustment, and will degrade
the tuning torque, adjustment life, and other
mechanical specifications.
In general, the minimum exposure to cleaning solu-
tions is recommended. The gentlest would be the
detergent and water rinses at fairly low tempera-
tures. When chlorinated or fluorinated hydrocarbons
are used, the boards should never be plunged into
the solvent solution, but rather maintained in the
vapor area of the defluxing equipment, and for the
minimum possible time. Most desirable would be to
clean only the bottom of the printed circuit board,
as with board scrubbers.
The unsealed GKG models are usually specified for
consumer applications where cleaning after soldering
is normally not required. Should cleaning be required,
the method to use would be to clean the bottom of
the board, as with board scrubbers. If a solvent is used
when cleaning the GKG series, sealed versions should
be specified to prevent the solvent from being
trapped in the housing and degrading performance.
Other precautions for using ceramic trimmer capaci-
tors include:
• Beware of excessive handling with bare hands
• Terminals should not be cut or reformed, as this
as, “finger oil” and dirt can bring down Q and
insulation resistance values.
could cause deformation of the spring or break-
ing of the rotor.
