Low ESR MnO
Soldering Process
KEMET’s families of surface mount capacitors are compatible
with wave (single or dual), convection, IR or vapor phase reflow
techniques. Preheating of these components is recommended
to avoid extreme thermal stress. KEMET's recommended
profile conditions for convection and IR reflow reflect the
profile conditions of the IPC/J-STD-020D standard for moisture
sensitivity testing. The devices can safely withstand a maximum
of three reflow passes at these conditions.
Note that although the X/7343-43 case size can withstand wave
soldering, the tall profile (4.3 mm maximum) dictates care in wave
process development.
Hand soldering should be performed with care due to the difficulty
in process control. If performed, 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 termination, until reflow occurs. Once reflow occurred, the
iron should be removed immediately. "Wiping" the edges of a chip
and heating the top surface is not recommended.
During typical reflow operations, a slight darkening of the gold-
colored epoxy may be observed. This slight darkening is normal
and is not harmful to the product. Marking permanency is not
affected by this change.
