One pixel of M1615 still failed mask test but it was not taken in to account in the final grading???
I put it in the shelves for Module doctor. To be decided what to do with this module. |
For Wolfram one channel of M1615 does not work. He noticed that the cable has corrosion (probably this cable has been attached to a module that has been irradiated in Zagreb). After Reception test this module again graded C due to a mask test failure of one pixel in one ROC.
Wolfram proposed to grade this module as C*.
