12. General Information
(1) Storage
The products shall be stored at 10°C to 35°C at the
humidity of 30% to 70%. The products shall not be
stored where they are exposed to harmless gases.
(Ex. Hydrogen chloride, Sulfurous acid gas or
Hydrogen sulfide) Soldering shall be done 12 months
since delivery. When the former requirements are
not satisfied, the solderability test shall be done
prior to soldering.
(4) Cleaning
Cleaning using isopropyl alcohol shall be done at a
temperature of 60°C or less within 5 minutes. It has
been checked that the products aren’t damaged by
ultrasonic cleaning at a cleaning agent temperature
of 60°C or less, a frequency of 28kHz and a power
of 20W within a minute.
(6) Pattern design
The land pattern is recommended as follows.

(3) Soldering
Ceramics are in general very sensitive to thermal
shocks. Therefore the products shall not be exposed
to a sudden temperature increase, decrease or partial
heating. Preheat shall be done before using the
soldering iron (ex. Hot wind etc.) Temperature
difference between temperature of soldering iron tip
and temperature of the products shall not exceed
130°C. The soldering iron shall not contact directly
with the product, in order to avoid damage to the
product. It is desirable that soldering temperature
is 240°C to 250°C. Flux shall be colophony type.
Strong acid type flux shall not be used. Wattage of the
soldering iron shall be 20W or less at the temperature
of 220°C to 250°C. The tip of soldering iron shall be
3ø or less. Application time of the soldering shall be
4 seconds or less.
