Chemical Resistance
Ceramics themselves are very resistant to chemical attack,
providing they are processed in a manner which prevents
the incidence of cracks or chips in the body. In cases where
cracks etc. are present, moisture can penetrate and cause
insulation resistance to reduce.
Termination, whether silver/palladium or nickel barrier solder
coated, can suffer chemical attack from pollutants in the air
or packing materials. In order to preserve their solderability
they should be kept in the packing the manufacturer sup-
plied until required for use. Points to watch are the use of
paper and rubber bands, which contain sulphur com-
pounds.
Handling
Ceramic chips can easily be damaged and contaminated by
poor handling or storage. A chip or crack, contamination by
hands or poor storage, use of metal tweezers (the surface
or bare ceramic chips is very abrasive) can all induce subse-
quent defect as described above. Care must be taken to
achieve the best results.

This merely confirms the well known high strength in com-
pression, low strength in tension that ceramics normally
have.
TERMINATION TYPES &
APPLICATIONS
The capacitor termination must be designed so that it has
(a) a good electrical connection to the internal electrode sys-
tem and (b) has good solderability and leaching properties
with normally used fluxes, solders and soldering processes.
Surface mount assembly has permitted the use of a wider
range of soldering processes than was traditionally viable for
pin-through hole manufacture.
This has, in turn, placed greater demands on the capacitor
terminations, especially with regard to wave-soldering and
some of the more prolonged reflow techniques.
Storage
Good solderability is maintained for at least twelve months,
provided the components are stored in their “as received”
packaging at less than 40°C and 70% relative humidity.
Solderability
Terminations to be well tinned after immersion in a 60/40
tin/lead solder bath at 230 ±10°C for 5 ±1 seconds.
