Attachment Methods - Opti-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
Opti-Caps

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