P21BN300MA04733 Opti - Cap®
April 2011
Recommended Attachment to Soft or Hard Substrate Using Conductive Epoxy:
Recommended Micro Strip Layout:
Gap:
.008” - .010”
Epoxy Thickness:
.003” - .005”
Ideal Micro Strip Width:
.012” - .015”
Epoxy Diameter:
.005” - .008”
Distance from Trace Edge:
.003” - .004”
Attachment Method
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 Milli-Cap® 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!
Attach with Milli-Cap® Down
