Patent ID: 8872534

Claim:
A probe card assembly comprising: a connector configured to connect to and receive voltage, analog signals, or digital signals from a test resource; probes configured to contact and thereby make pressure electrical connections with a device under test; and an electric circuit comprising: input terminals connected to said connector, output terminals connected to said probes, intelligent switch modules, each said intelligent switch module comprising a switch that connects one of said input terminals to one of said output terminals and a current sensor configured to sense current flowing through said switch while said switch is closed, wherein said intelligent switch module is configured to open said switch when said current exceeds a programmed threshold current, and control logic configured to selectively program said threshold current for each of said intelligent switch modules; wherein each of said intelligent switch modules further comprises debounce logic configured to cause said intelligent switch module to open said switch when said current exceeds said programmed threshold current for a programmed threshold time period.
