Production yield so far |
|
|
Of 41 modules produced and tested so far (1536-1576), 6 modules were found to be bad before or during the reception test, 5 were graded C after the full qualification (one of which is possibly C*) and the remaining 30 modules were graded B (of which 4 were manually regraded from C to B).
The overall yield for good modules (A+B/Total) produced so far is (30/41)=73% |
