Number of wafers on one ladder batch: 53,
Qualities accepted : 1 2 3 6 ,
Minimal operating range is 15 volts.

Sort on 395 wafers,
wafers unproper for association (already on ladder/bad modules/wafer by Thales): 39 ( 16/ 13/ 10),
wafers associated by this algorithm: 349,
wafers not associated to any batch: 7.

Result: FAILED, ladder build: 19

For 1 ladder batch(es):

Ladder batch 7: 22 wafers missing
