Abstract:
The present disclosure provides a system and method for providing electrostatic discharge protection. A probe card assembly is provided which is electrically connected to a plurality of input/output channels. The probe card assembly can be contacted with a secondary assembly having an interposer electrically connected to one or more wafers each wafer having a device under test. Voltage can be forced on ones of the plural input/output channels of the probe card assembly to slowly dissipate charges resident on the wafer to thereby provide electrostatic discharge protection. A socket assembly adaptable to accept a 3DIC package is also provided, the assembly having a loadboard assembly electrically connected to a plurality of input/output channels. Once the 3DIC package is placed within the socket assembly, voltage is forced on ones of the input/output channels to slowly dissipate charges resident on the 3DIC package to thereby provide electrostatic discharge protection.
