Recommended Soldering Conditions
Recommendations and precautions are described below.
● Recommended soldering conditions for refl ow
Recommended soldering conditions for soldering iron
When soldering with a soldering iron, or when correcting defective soldering on parts after PWB mounting, solder
following these guidelines.
● If the Adjustable (pre-set) Ceramic Capacitor is soldered exceeding the temperature range, functions or characteristics
● In addition, the tip must not directly touch the part other than on the terminals.
(1) When mounting Adjustable (pre-set) Ceramic Capacitor on PWB, set the capacitor in such a position and direction

(2) Flux
of the capacitor may degrade due to heat stress.
Otherwise, distortion due to thermal shock grows, and functions of the capacitor may degrade.
· Solder tip temperature : 380±10 °C
· Soldering time : 3 s max.
· Please contact us for additional information when used in conditions other than those specifi ed.
· The profi le error may greatly differ depending on the measuring method.
· The temperature varies according to the size of board or installation density.
that it is free from the effects of PWB warping and defl ection.
Mechanical stress due to PWB warping or defl ection may cause the functions or characteristics of the capacitor to
degrade.
1 Position : Do not place a capacitor near PWB cuts or broken parts.
2 Direction : Place the capacitors horizontal to the direction that the stress is applied.
1 Select f3.8mm min. (3.8 mm if the contour is a square) for the outer diameter of the nozzle when mounting
2 When mounting Adjustable (pre-set) Ceramic Capacitors on PWB, make sure that excessive pressure (3.92 N) or
3 Attach the product in close proximity to the PWB.
1 Use fl ux containing less than 0.1 wt% (converted into chlorine) of halogen type substances. Do not use strong acid fl ux.
2 Amounts of Flux used during soldering.
Therefore please check the temperature for every type of board that may be used.

shock is not applied.
If the Adjustable (pre-set) Ceramic Capacitor is mounted with a force exceeding the specifi ed pressure,
functions of the capacitor may degrade.
Functions or characteristics of the capacitor may degrade if stress is concentrated at the terminals,
due to load and rotation torque caused during adjustment.
If the halogen content is high, or strong acid fl ux is used the remaining fl ux after soldering may cause corrosion of
terminals or reduction in insulation resistance.
If not enough Flux is used, insuffi cient fi xing may occur. If the amount is too large, fl ux may get inside the product
and may cause the characteristics or functions or the capacitor to degrade.
