vibrating frequency 10 to 55Hz, one cycle 60 seconds to direction
of X,Y,Z for each 15 minutes,(Total 45minutes) and after
removing vibration(Non-operation state)
To be measured after dropping from 60cm high onto steel board
of 15mm thick and from 3 direction X,Y,Z each one time
(Non-Operation State)
- Condition:150pf, 330 , ±8KV, 5 times Air Discharge
(ESD which is made by above condition should be shot on LCD
glass panel, not other's area(such as on IC and so on)
- After testing, cosmetic and electrical defects should not happen.
- Total current consumption should be below double of initial value.
- In case of malfunction defect caused by ESD damage, if it would
be recovered to normal state after resetting, it would be judged as
a good part.
