already did this test. No solder balls. i have printed the pads without the component. No solder balls. Only with the component. The problem is, it splashing the around components. solder balls wew found on the body of a connector and on top of it. This is already strange. With the rest of the SMT components there is no problem. Only with this capacitor.
