Another solution to look at is an anti-tombstoning paaste produced by Multicore. It is a blended powder of two alloys and sizes that seems to really work.

Hello to All,

We have had tombstoning in a Film Chip Capacitor (Size 1206).
It is being soldered in a normal reflow process, and this is the only
component that it is showing tombstoning.
Reviewing the specs. of the component in the web I found that this
capacitor is recommended for Wave Soldering.
Does anyone know the difference in construction between the Capacitors for
Reflow and Wave Soldering?
Is it possible that this be cause for the tombstoning?
I am also sending pictures for cross section for the capacitors that we are
using (Recommended for Wave Soldering).
They could be seen at Steve's site.

Regards

Alejandro Becerra
