Table 6 - Land Pattern Dimensions for Reflow
Solder
31. Soldering
The A700 - AO-CAP family has been designed for
reflow solder processes, or for wave soldering. The
solder-coated terminations have excellent wetting
characteristics for high integrity solder fillets.
Preheating of these components is recommended to
avoid extreme thermal stress. Figure 6 represents
the recommended maximum solder temperature/
time combinations for these devices.
Hand-soldering should be avoided. However, if nec-
essary it should be performed with care due to the
difficulty in process control. Care should be taken to
avoid contact of the soldering iron to the molded
case. The iron should be used to heat the solder
pad, applying solder between the pad and the termi-
nation, until reflow occurs. The iron should be
removed. "Wiping" the edges of a chip and heating
the top surface is not recommended.

dering recommendations.
32. Washing
Standard washing techniques and solvents are com-
patible with all KEMET surface mount aluminum
capacitors. Solvents such as Freon TMC and TMS,
Trichlorethane, methylene chloride, prelate, and iso-
propyl alcohol are not harmful to these components.
Please note that we are not endorsing the use of
banned or restricted solvents. We are simply stating
that they would not be harmful to the components.
If ultrasonic agitation is utilized in the cleaning
process, care should be taken to minimize energy
levels and exposure times to avoid damage to the
terminations.
KEMET AO-CAPS are also compatible with newer
aqueous and semi-aqueous processes.
33. Encapsulations
Under normal circumstances, potting or encapsula-
tion of KEMET aluminum chips is not required.
34. Storage Environment
AO capacitors are shipped in moisture barrier bags
with a desiccant and mositure indicator card. This
series is classified as MSL3 (Moisture Sensitivity
Level 3). Upon opening the moisture barrier bag,
parts should be mounted within 7 days to prevent
mositure absorption and outgassing. If the 7 day
window is exceeded, the parts can be dryed per the
instructions on the bag (168 hours at 40 ± 5°C).
AO capacitors should be stored in normal working
environments. While the chips themselves are quite
robust in other environments, solderability will be
degraded by exposure to high temperatures, high
humidity, corrosive atmospheres, and long term stor-
age. In addition, packaging materials will be degrad-
ed by high temperature (reels may soften or warp,
and tape peel force may increase). KEMET recom-
mends that maximum storage temperature not
exceed 40 degrees C, and the maximum storage
humidity not to exceed 60% relative humidity. In
addition, temperature fluctuations should be mini-
mized to avoid condensation on the parts, and
atmospheres should be free of chlorine and sulfur
bearing compounds. For optimized solderability, chip
stock should be used promptly, preferably within 1.5
years of receipt.
