Thermal cycling test (6)
Thermal cycling test start (6.3)
Monitor the resistance increase
to initial resistance (6.4)
20 % or more increase
to the initial resistance is detected
for five consecutive reading scans
(6.5)
No (Pass)
Yes (Failure):
Five consecutive reading scans or more
Suspend thermal cycling test.
