Improvement Actions Related to Cost

• Evaluation of LTX new PECHF relay

• Looked for local service : Buying LCD instead of CRT, Snubbors, flower sensors. (CRT : Transportation + repair cost = nt 14xxxx + usd $800 )

• Heat-exchanger local solution.

• Look for consumable parts from local vendor.

• Repair PSCM, THBUF.

Evaluation of LTX new PECHF relay

newold

• 60% of PECHF fault causes are related to relay’s reliability.

• The results after the evaluation of LTX new PECHF relay.

Failure rate of PEC’s was slightly higher on the ZTR tester through 3 months.

Replacing all relays during repair does not improve reliability.

LTX have already implemented the above measures in repair.


Heat-exchanger local solution

• Purpose of request : To get stable temperature(17 centigrade ) + Cost saving.

• Real status in use : Same function as origin.

• Getting from LTX is (USD): $5900/ea

• Buying from local vendor is NT 5XXX/ 2ea


Bottle Necks On Fusion

• Hardware and software upgrade frozen.

• NPF (No Problem Found) control.

• DFCP control.
