Capacitors connected GND to GND

Why capcitors connected Ground to ground ? what is the need? and what is the value of these capacitors?

  • If the ground traces are too thin, maybe the designer wanted to reduce the AC impedance without creating a DC ground loop. If there is no value, it usually means the designer wasn't sure what value would work best. The designer may have wanted the option to replace the cap with a short or simply leave it unpopulated to see what worked better.
