Subject: Pressure Sensor MTBF
I'm working on MTBF prediction on a pressure sensor that the vendor didn't have test data to support reliability prediction. The pressure sensor is a piezoresistive pressure sensor chip attached to a ceramic substrate. The sensor has four thick film resistors laser trimed on ceramic forming a Wheatston bridge. Any help on how to calculate MTBF will be very appreciated.

Subject: RGA or Water Vapor Content Testing
My company has always required it's suppliers of hermetically sealed active devices (used on military aircraft) to perform RGA testing on sublots of their production material.
These are devices such as RF Switch assemblies, amplifiers, filters, etc. I'm getting feedback from many of my suppliers that this should be done as a one time qualification test only and not as a periodic test. I was wondering if you have any supporting documentation to support either position. Thank you, Larry

Where can I find guidelines in establishing an aging aircraft wiring integrity program. I have seen web articles that discuss the advantages of such a program, but need to find information relating to the establishment and structure.
