Wafer Probing Info


The following modifications should be made to the Probe Card (FE-I4A only)

  • Add solder jumper to right side of T1
  • Add solder jumper to VTH_INT1
  • Add solder jumper to VBB_INT1
  • Remove R11
  • Remove C31
  • Add jumper to right contacts of tristate jumper CMD_CHIPID0
  • Add jumper to right contacts of tristate jumper CMD_CHIPID1
  • Tristate jumper T3_PAD should be connected to Vdda1

  • Jumper needs to be added to 3_3VEFUSE pins to power LEDs.
  • Right LED turns on at first contact between needle and bond pad.
  • Left LED turns on after approximately 20um of overdrive.
  • Right LED remains ON after needles retracted (?). Needle bent or not returning to original position (?).

Procedure for adding a Probe Station to STControl

  • Control of Probe Stations in STControl is handled in the PixLib package.
  • The PixLib package is usually located in 'C:\USBpixI4\host\trunk\Applications\Pixel'
  • Control of the new probe station should be written as a class (.cxx/.h) inheriting from the abstract class PixProber.cxx/.h
  • The new probe station class (NewPixProber.cxx/.h) should be saved in the Applications\Pixel\PixLib\PixProber folder .
  • Add the following lines to the PixProber.cxx file
    • Add header file for the new probe station, e.g. #include "PixProber/NewPixProber.h"
    • Add code for NewPixProber to PixProber::make and PixProber::listTypes constructors
  • Add the new probe station class files to the PixProber Make files (Makefile and Makefile_windows)
  • Add the new probe station class files to the main PixLib Make files (Makefile and Makefile_windows)
  • Add additional headers and/or libraries needed for control of your prober (e.g ni4882.h, visa.h, visatype.h, visa32.lib) to the inc and lib folders in C:\USBpixI4\host\trunk
  • Do a full compilation of the code from C:\USBpixI4\host\trunk
  • See instructions for compiling on Updating USBPix
  • Your probe station should now appear in the list of probe stations in the wafer panel in STControl
