I wonder if that cap you are seeing is not a temporary measure, for storage and transport purposes. I agree, it does look like it's shorting out all the pins.

I wonder if that cap you are seeing is not a temporary measure, for storage and transport purposes. I agree, it does look like it's shorting out all the pins. Maybe it's intentional, to avoid any weird currents or whatever forming while the chips are not installed? Possibly an early form of ESD protection?
