Subject: Automotive electronic system failure rate
Message:
I am looking for failure rate information of electronic systems used in automotive, specifically inside the passenger compartment. What is the failure rate generally acceptable for systems like radar detector, GPS, radio, CD, etc., 0.1% per year? Also, what is the operation life time expected for those systems, 2 hours/day for 10 years, something like that? Thanks.

Subject: Kapton insulated flexible circuits
Message:
Does anyone have information regarding the fielded or predicted reliability of Kapton (polyimide) insulated flex circuits. Our potential airborne application is with a "twist-flex capsule" in a turret assembly. Please note the distinction between flexible circuit and lead wire. I'm well aware of the widely documented "arc tracking" failure mechanisms associated with bundled Kapton-insulated lead wire on aircraft. My goal is to assess the probability of arc tracking occurring with single layered flex circuits, not lead wire. Any help would be appreciated.

Can anyone recommend a good source of independent information regarding the reliability/MTBF figures that are available for LCD displays used in notebook computers?

Subject: MIL-HDBK-217
Message:
We are in process of updating reliability predictions from previous revisions of MIL-HDBK-217. Specifically from 217 Rev C, and 217 Rev F to 217 Rev F, CN2.The question is what would be the anticipated deltas in failure rate between the different models. If specific information is not available, then I would appreciate any general comments relating to this subject. We would like to use this as a sanity check for the results we are obtainig.
