Patent ID: 6984998

Claim:
A multi-function probe card, comprising: a PCB ( 41 ); a plurality of probe needles ( 47 ), an end of each of the probe needles ( 47 ) is connected to the PCB ( 41 ); a counter ( 71 ), for detecting the probe needles ( 47 ) to count the piece of the DUT bare die ( 46 ) and generate a “piece sequence parameter”; a signal-measuring device ( 72 ), for measuring the current and voltage passing through the probe needles ( 47 ) to generate current and voltage parameters; and a parameter processing system ( 74 ), further comprising an I/O unit ( 51 )/( 59 ), a processing unit ( 52 ), a time providing unit ( 55 ), a real time display unit ( 56 ), and a storing unit ( 57 ); whereby, the “piece sequence parameter” as well as the current and voltage parameters can be input into the processing unit ( 52 ) through the I/O unit ( 51 )/( 59 ); the processing unit ( 52 ) employs the “piece sequence parameter” as a datum for piece of DUT while the “time providing unit” ( 55 ) provides processing unit ( 52 ) with a time datum for each of the DUT bare dies ( 46 ); thereafter, the processing unit ( 52 ) sets up a parametric data structure in terms of the piece datum of the DUT bare die ( 46 ), current parameter, voltage parameter, and time datum for recording the service process and condition of the probe; subsequently, the processing unit ( 52 ) real timely calculate the conditions of the probe card ( 40 ) and display the service process and conditions of the probe card ( 40 ).
