¾ Attachment Method
1. Place a single drop of solder paste onto each micro-strip as illustrated; the edge of the epoxy 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 Milli-Caps®.
