Set bin#

A test that can be used to add binning information of a test to the probe station wafermap die or subsite.

Description#

Set the bin value of a die or a subsite. Bin is set to the current die or subsite at the probe station wafermap. Measmatic always forward the first bin thrown in the tests prior to the binning.\ The binning test requires a set site information in Measmatic, for example by using the Site Stepping.\ If a subsite index is present the bin value is applied to the subsite with the given index. If no subsite index is given the bin is applied to the die. Omitting column and row parameter will apply the binning to the current die as per the active routing table. If only one subsite is present subsite binning will be refused.

Input parameters#

The test requires to select a probe station, added in the device manager.

Output parameters#

The test does not provide output parameters.

Supported devices#

The following devices are supported by this test:

  • MPI SENTIO Software Suite
  • Velox Software Suite (FormFactor Inc.)

Example#

Hardware setup:

Connect a supported Waferprober to the computer running Measmatic over TCP/IP, GPIB or RS232.

In the device manager add the Waferprober to the current test site configuration. Change the name, the IP address in the device properties of the device. If needed, increase the communication timeout for the probe station device.

Measmatic setup: or

  1. Add a Site Stepping test to the test sequence by dragging and dropping a Site Stepping test from the test picker into the test sequence. Set the Probe station in the Site Stepping test to be the Probe station added in the device manager. Enable Automatically move chuck to contact . Alternatively enable Include all active sub-sites.\
  2. Add a measurement test into the Site Stepping loop. Set the Test output parameters and select a fail bin criteria. In the Example a Demo Data generator creates float numbers between 0 and 100 with a test pass criteria of a result between 25 and 75.\
  3. Add Set bin into the Site Stepping loop. Set the Probe station in the Site Stepping test to be the Probe station added in the device manager.\
  4. Execute the test sequence by pressing the Run all tests button.\
