Attachment Methods - Milli-Capº
Recommended attachment to soft or hard substrate using
Conductive Epoxy
1. Place a single drop of conductive epoxy onto each micro strip
as illustrated; the edge of the epoxy shall be at least .003”- .004” back
from the edge of the trace to prevent filling the gap with epoxy.
2. Centering the termination gap of the capacitor within the gap in the
micro strip, press with careful, even pressure onto the micro
strip ensuring the terminations make good contact with the
epoxy drops.
3. Cure according to the epoxy manufacturer’s preferred schedule,
typically 125°C to 150°C max.
4. After curing, inspect joint for epoxy shorts across the termination and
micro strip gaps that would cause a short across the cap.
Isopropanol and Methanol are both safe to use to pre clean
Milli-Caps®.
Recommended attachment to soft or hard substrate using Solder
1. Place a single drop of solder paste onto each micro strip as illustrated;
the edge of the solder shall be at least .001”- .002” back from the edge
of the trace to prevent filling the gap with solder.
2. Centering the termination gap of the capacitor within the gap in the
micro strip, press with careful, even pressure onto the micro
strip ensuring the terminations make good contact with the drops of
solder paste.
3. Reflow according to the solder manufacturer’s preferred profile,
ensuring the reflow temperature does not exceed 250°C.
10110/17/v2
4. After the reflow step is completed, inspect joint for voids or excess flux
and non-reflowed solder balls that can degrade performance or cause
shorts across the gaps. Proper cleaning after the reflow process is crucial
to avoiding performance degradation and discovering poor solder joints.
Isopropanol and Methanol are both safe to use with soldered Milli-Caps®.

Isopropanol, and Methanol are not to be used after mounting with
conductive epoxy as they act as a solvent!
