The document contains quarterly and monthly operational uptime and electronic mean time between failure (E-MTBF) metrics for LTX test systems from 2002-2004. It shows that: 1) LTX operational uptime improved each quarter and exceeded 98% targets by Q3 2003. 2) E-MTBF numbers increased each quarter, with a significant jump in Q3 2003. 3) The Fusion HF sub-cluster had the highest E-MTBF numbers, reaching over 700 in Q3 2003.

•Synchro AC still have a large gap between target.
•Fusion get improvements :
Less problem in Fusion cooler .
Ext-cooling are more stable after clean all.
Factory power is more stable than before .

18. MTTR:
•Good trend : All MTTR 2003’s MTTR is lower than 2002’s.
•Bad trend :
1. More difficult application problems.
spend us much time in failures analysis ,pre-srcreen and double-
check .
2. Om635X series has “high_Z mode” hang problem.
3. PCD6001’s test time would increase one by one .

22. PSK’s concern
The reliability & quality :
1.PECHF had 200 cases .It is higher than 2002 .
2.SMS_Dig ,SMS_HS head card and SMS HR also had higher failure
rates in 2003.
3.DOA+DUW in 2003 > 2002.
Does supplier guarantee the reliability & quality ?

25. PSK’s concerns:
1.Parts reliability .
2.Average delivery time still have big gap to target.
3. Higher cost in spare parts , we increase 33 % in 2003 of LSI.
more than 2002 ,Does supplier help customer in cost down?
2002 LSI 71 pcs ,LSI cost : $109,513 .
2003 LSI 95 pcs , LSI cost : $ 158,384 .
