There is no solution in above case, this is caused by the PCB design. There are no thermals on the pads connected to the copper poured area. So the other pad reflow first and lift the component.

Anyone who knows how to prevent such flaw? Tombstones are those lifted components from one sides. This results in costly and time-consuming amounts of touch-up and re-work after the assembly is completed. For the customers, this extra work translate

The only way can detect, play around with your vision teaching with the component. and adjust the pin tolerance.

I do not see anything obvious that would cause a thermal mis match. Regarding reflow profiles reducing tombstoning, Unless there is something wrong with your paste or you are running smaller than 0402's, I have NEVER seen a reflow profile reduce tom

Not enough solderpaste. Uneven solderpaste volume on pads. Bad quality of caps ( Metal ends), try new cap manufacturer, sound weird, huh!! but that happened to me. Good luck.
