Hi, Jorge, Which specs are you working to for your quality standard? That should determine whether you have a defect or not. You certainly have an anomaly, though. Can that solder tail be broken off (easily)? It doesn't appear to be large enough to be causing, or likely to cause, any trouble if it stays where and how it is. If it breaks off, that's more of a problem, and will be a defect. What do these components look like before you start to assembly them onto boards? Any signs of a condition that might attract solder? Haven't seen anything like this myself, so can't suggest a cause, but since solder doesn't stick to ceramic, there must be something else on the chip that permits solder to wet beyond the component's end caps. More clues would be good - Is it the same component type / part number / batch number / position on board each time it happens? Are you wave soldering these?
