The module is graded A after reception test.
I'm still not sure that wire-bonds of the new TBM is lower than capacitors. I'll try to glue a cap tomorrow
to see whether we could substitute TBMs on another 6 modules with broken TBMs. |
Cap has been glued to M1546. No damaged wire-bonds. Vthr-CalDel and PixelAlive are OK.
Module to be (FT) tested tomorrow. |
