Problem Description
MGX-RPM-XF-512 boards from certain PCB lots experience early mortality failure and a higher than expected Dead On Arrival rate.
Statistical analysis indicates a service life less than the published standard for the affected boards.
Background
Some assemblies of the MGX-RPM-XF-512 boards built between November 2006 and February 2007 utilized PCB boards from two specific vendor lot numbers. Analysis of failures from those boards built from the lot numbers indicates a higher that expected failure rate, due to suspected micro cracking in the PCB substrate.
Problem Symptoms
There is no single symptom of failure. Boards will fail for one of multiple possible reasons, depending of where the micro crack develops on the substrate and which component is installed on top of that board region.
Workaround/Solution
Solution
Replace all boards with a serial number matching those listed with a new board unaffected by this issue.
