Avionics

Semiconductor Fabrication Standards cover the production process of semiconductors. Given the importance of clean rooms, these standards address gas distribution in that context, as well as the use and quality of water. Additionally, IEC 62258 provides information about semiconductor die products. Other topics of importance are included as well, such as EM immunity, examination of semiconductors, and aerospace-specific requirements.

IEC/TR 62240-1 Ed. 2.0 en:2018

Process management for avionics - Electronic components capability in operation - Part 1: Temperature uprating

IEC TR 62240-1:2018 is a technical report, which provides information when using semiconductor devices in wider temperature ranges than those specified by the device manufacturer. The uprating solutions described herein are considered exceptions, when no reasonable alternatives are available; otherwise devices are utilized within the manufacturers’ specifications. This document describes the methods and processes for implementing this special case of thermal uprating. All of the elements of these methods and processes employ existing, commonly used best engineering practices. No new or unique engineering knowledge is needed to follow these processes, only a rigorous application of the overall approach. The terms “uprating” and “thermal uprating” are being used increasingly in avionics industry discussions and meetings, and clear definitions are included in the present IEC Technical Report. They were coined as shorthand references to a special case of methods commonly used in selecting electronic components for circuit design. This new edition cancels and replaces the first edition published in 2013 and includes a revised wording for subclause 4.1 (Introduction to selection provisions) and the associated flowchart.

IEC/TS 62686-1 Ed. 3.0 en:2020

Process management for avionics - Electronic components for aerospace, defence and high performance (ADHP) applications - Part 1: General requirements for high reliability integrated circuits and discrete semiconductors

IEC TS 62686-1:2020 is available as IEC TS 62686-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC TS 62686-1:2020 defines the minimum requirements for general purpose "off the shelf" COTS (commercial off-the-shelf) integrated circuits and discrete semiconductors for ADHP (aerospace, defence and high performance) applications. This Technical Specification applies to all components that can be operated in ADHP applications within the manufacturers' publicly available data sheet limits in conjunction with IEC TS 62239-1. It may be used by other high performance and high reliability industries, at their discretion. This new edition includes the following significant technical changes with respect to the previous edition: - update related to obsolescence of STACK Specification S/0001 revision 14 notice 3; - addition of alternative automotive methods of compliance and revision of Annex B initially related to cross-reference to STACK Specification S/0001; - addition of an Annex C to include a requirement matrix for IEC TS 62686-1 verification.

SAE GEIASTD 0002-1A-2015 (SAE GEIASTD0002-1A-2015)

Aerospace Qualified Electronic Component (AQEC) Requirements, Volume 1 - Integrated Circuits and Semiconductors (Stabilized: Mar 2015)

This Standard applies to integrated circuits and semiconductors exhibiting the following attributes: a. A minimum set of requirements, or information provided by the part manufacturer, which will allow a standard COTS component to be designated AQEC by the manufacturer. b. As a minimum, each COTS component (designated AQEC) will have been designed, fabricated, assembled, and tested in accordance with the component manufacturer's requirements for standard data book components. c. Qualification of, and quality systems for, the COTS components to be designated as AQEC shall include the manufacturer's standards, operating procedures, and technical specifications. d. Components manufactured before the manufacturer has addressed AQEC requirements, but utilizing the same processes, are also considered AQEC compliant. e. Additional desired attributes of a device designated AQEC (that will support AQEC users) are found in Appendix B of this standard. NOTE: Parts qualified to military specifications (except those identified as being for "logistic support purposes only" and/or having expressed limitations on their airborne use) are considered AQEC; the remainder of this standard only addresses non-military specification parts.
