Subject: 4 modules FT 
FullQualification of four modules M1526, M1529, M1521 and M1534 has been done. Full time of the test is about 5.5hrs.
Test included: FT@-20C, IV@-20, 3Cycles from -20C up to +10C, FT@10C and IV@10C.
Only M1521 passed the test (Grade B). Several issues observed in other modules:
1) 2-6 ROCs with TrimBit test failure for many pixels
2) Trimming id bad for some ROCs
3) test at +10C often better than at -20C
4) some ROCs hav issues with Thr and Gain distributions (out of specifications)

To be understood before the mass production!
