Abstract
A probe card includes an adapter plate, a guide plate and a plurality of probes. The guide plate incudes a first guide plate portion, a second guide plate portion and a capacitor structure. The probes include at least one first ground probe, at least one second ground probe and a plurality of power probes. The first ground probe penetrates through the first guide plate portion and is connected to the capacitor structure and the adapter plate. The second ground probe and the power probes penetrate through the first guide plate portion, the capacitor structure and the second guide plate portion and are connected to the adapter plate. The first ground probe is used to provide voltage to the capacitive structure to generate a potential difference. The power probes draw current through the capacitor structure and form a current loop with the second ground probe.
