Flow Soldering
(1) Don not immerse the c a p a c i t o r body into the
solder bath as excessive internal pressure could
result.
(2) Observe proper soldering conditions (temperature,
time, etc.). Do not exceed the specified limits.
(3) Do not allow other parts or components to touch
the capacitor during soldering.
2.5
Reflow Soldering for Chip Capacitors
(1) For reflow, use a thermal conduction system such
as infrared radiation (IR) or hot blast. Vapor heat
transfer systems (VPS) are not recommended.
(2) Observe proper soldering conditions (temperature,
time, etc.). Do not exceed the specified limits.
(3) Reflow should be performed one time. Consult us
for additional reflow restrictions.

2.6 Other Soldering Considerations
R a p i d t e m p e r a t u r e r i s e s d u r i n g t h e p r e h e a t
operation and resin bonding operation can cause
cracking of the capacitor vinyl sleeve. For heat
curing, do not exceed 150 C for a maximum time of
2 minutes.
2.7 Capacitor Handling after Soldering
(1) Avoid movement of the capacitor after soldering
to prevent excessive stress on the leadwires
where they enter the seal.
(2) Do not use the capacitor as a handle when
moving the circuit board assembly.
(3) Avoid striking the capacitor after assembly to
prevent failure due to excessive shock.
2.8
Circuit Board Cleaning
(1) Circuit boards can be immersed or ultrasonically
cleaned using suitable cleaning solvents for up
t o 5 m i n u t e s a n d u p t o 6 0 C m a x i m u m
temperatures. The boards should be thoroughly
rinsed and dried.

The use of ozone depleting cleaning agents are
not recommended in the interest of protecting
the environment.
(2) Avoid using the following solvent groups unless
specifically allowed for in the specification;
Halogenated cleaning solvents: except for solvent
resistant capacitor types, halogenated solvents
can p e r m e a t e t h e s e a l a n d c a u s e i n t e r n a l
capacitor corrosion and failure. For solvent

specificaion. 1-1-1 trichloroe thane should never
be used on any aluminium electrolytic capacitor.
Alkali solvents: could attack and dissolve the
aluminum case.
Petroleum based solvents: deterioration of the
rubber seal could result.
Xylene: deterioration of the rubber seal could
result.
Acetone: removal of the ink markings on the
vinyl sleeve could result.
