5.4 Timing Diagram
Test Process Control
T1 > 10mS
It sets the time required for external trigger signal
(/EXT_START) to sustain.
T2 < 20mS
It sets the time for clear from external trigger signal
(/EXT_START) to /EOT signal.
It sets the time required for test.
It sets the waiting time for /PASS_FAIL signal to be stable.
T5 > 5mS
It sets the waiting time for /EOT and /EOS signals to be
stable.
It is the time spent to switch step.
It is the time spent for starting 2
nd
test.
The value is varied by conditions. For instance, the T6 under the condition of
Screen On is about 320mS and under the condition of Screen Off is about 40mS,
while the T7 under the condition of Screen On is about 280mS and under the
condition of Screen Off is about 60mS. (The values mentioned here are estimated,
the exact values shall base on the actual measurement.)
