Hi Yi,

You can find a picture of the tool on slide 11 
https://drupal.star.bnl.gov/STAR/system/files/FSTPrototypeModuleTest.pdf

A main reason we chose this tool is because of its L shape, which allowed us 
to access the connector while the module is in the storage box, so that the 
space between the connector and the storage box wall is very limited (see 
slide 2). I don’t think you have such a limitation since the readout chip or 
sensor is not mounted so that you don’t need to place the module inside the 
storage box.
