21. Concern Points
• Higher DOA & DUW rates.
That is a quality problem.
• Fusion’s digital power supply are all very sensitive to power cut.
Is there any protector on it?
• High fault rates on SMS_DIG , SMS_HR.
That is a quality problem.
• Seriously reworked boards are present in PSK.
Bad Q of on reworked parts. A PIZZA box to protect it shall be necessary. PSK
is unable to accept reworked parts with same CMI price.
• High NPF boards.
Does LTX run diagnostics with same OS as PSK?
