Taking the Stigma Out of Fiber Optics

2022-03-10
When faced with the predicament of designing or switching existing data cables to fiber optics, the choice on paper seems to be easy as fiber offers data rates at lengths that copper cannot achieve. Maintenance and sustainability considerations, however, must always be taken into account and these are the aspects that usually cause engineers to raise their eyebrows. When people hear �about the size of human hair� when describing the core of a fiber optic cable, they get both excited and concerned. On the one hand, you have the massive difference in weight between copper and glass, and on the other hand, the fragility that must come with it. Cable and assembly manufacturers now more than ever have the tools to convince all the naysayers that fiber is the way to go.

Capability Development: Make, Buy, or Outsource? That is the Question!

2022-03-10
Numerous challenges exist for avionics shops. The existence of avionics shops is questionable in the modern environment because many requirements must be fulfilled before a shop can maintain aircraft line replaceable units (LRUs). Specially in latest generation of aircraft (787, A350, 737-NG/Max, 777), Capability development is based on the 4M principle: Man, Machine, Material, Manuals. Every of those subjects can be a complicated path in capability development. This presentation will define a capability development workflow and touch on several important items that should be taken in consideration before capability can be launched. It is a complex and complicated process, but many useful standards can help shops and be used in continuous efforts to develop capabilities cost effectively. The journey is complicated, sometimes longer than expected, and full of obstacles.

TECHNIQUES FOR SUSPECT/COUNTERFEIT EEE PARTS DETECTION BY RADIATED ELECTROMAGNETIC EMISSION (REME) ANALYSIS TEST METHODS

2016-05-16
WIP
AS6171/14
The intent of this document is to define the methodology for suspect/counterfeit parts inspection using REME Analysis. The purpose of REME Analysis for suspect counterfeit part inspection is to detect misrepresentation or tampering of a part. REME Analysis can also potentially detect unintentional damage to the part resulting from improper removal of the part from assemblies, exposure to electrostatic discharge, exposure to radiation outside of acceptable limits (ionizing or high-power electromagnetic), or degradation. Improper removal of part from assemblies may include, but is not limited to, prolonged elevated temperature exposure during desoldering operations or mechanical stresses during removal. Degradation may include, but is not limited to, prolonged burn-in/testing, exposure to out-of-specification environmental conditions, or use outside of expected electrical tolerances.

WIP
AS6171/15
Non-conformance and now Suspect counterfeit packaging represents a hazard to electrostatic discharge (ESD) sensitive devices or components through cross contamination during transport and storage while generating high voltage discharges to ESD sensitive devices during in shipping, the inspection process, handling and manufacturing. Several aerospace related issues involve long-term storage supplier non-conformance with antistatic foams, antistatic bubble, antistatic pink poly, vacuum formed antistatic polymers, Type I moisture barrier bags and Type III static shielding bags have posed issues. The late John Kolyer, Ph.D. (Boeing, Ret.) and Ray Gompf, P.E., Ph.D. (NASA-KSC, Ret.) were advocates in the utilization of a formalized physical testing material qualification process. Today, however, prime contractors and CMs rely heavily upon a visual inspection process for ESD packaging materials.

WIP
AS6171/16
Netlist Assurance Test Methods exist to assess microcircuit designs for maliciously added, removed, or modified functions detrimental to system operation. In the context of the Microcircuit fabrication design process, these methods will be used to analyze a computer aided design (CAD) representation of the microcircuit. The Netlist Assurance Test Methods discover vulnerabilities, undisclosed functions (e.g. "kill switch", paths to leak passwords, or triggers of malicious activity) and changes from the original specifications of the devices. These methods are intended to be used with standard verification methods that the implemented design has remained unchanged through the many transformations in the design flow.
