Soldering Process
KEMET’s families of surface mount tantalum 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
sensitivety 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 (4.3mm maximum) dictates care in wave
process development.
Note 1: All temperatures refer to the center of the package, measured on the
package body surface that is facing up during assembly reflow.
