Part 1: Integrated circuits and discrete semiconductors
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

The main task of IEC technical committees is to prepare International Standards. In

exceptional circumstances, a technical committee may propose the publication of a technical

specification when

• the required support cannot be obtained for the publication of an International Standard,

despite repeated efforts, or

• the subject is still under technical development or where, for any other reason, there is the

future but no immediate possibility of an agreement on an International Standard.

Technical specifications are subject to review within three years of publication to decide

whether they can be transformed into International Standards.

IEC TS 62564-1, which is a technical specification, has been prepared by IEC technical

committee 107: Process management for avionics.

INTRODUCTION

Aerospace qualified electronic components (AQEC) plans are developed by manufacturers in

order to document compliance with AQEC requirements. For AQEC designated components,

the intention is to
a) provide AQEC users access to information from the AQEC manufacturers that is
necessary for using commercial-off-the-shelf (COTS) products;

b) better enable AQEC users to assess whether these parts are capable of operating reliably

in their applications;
c) minimize deviations from the AQEC manufacturers’ COTS products;
d) have minimal impact on the AQEC manufacturers’ standard operating or business
procedures;
e) promote communication between the AQEC manufacturers and users.

PROCESS MANAGEMENT FOR AVIONICS –
AEROSPACE QUALIFIED ELECTRONIC COMPONENTS (AQEC) –
Part 1: Integrated circuits and discrete semiconductors
1 Scope

This part of IEC 62564, which is a Technical Specification, defines the minimum requirements

for integrated circuits and semiconductors which are designated as an “aerospace qualified

electronic component (AQEC)”. It 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

should include the manufacturer’s standards, operating procedures, and technical
specifications. This information should be available when requested;

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 Annex B of this technical specification.

NOTE Parts qualified to military specifications (except those identified as being for “logistic support” purposes

only) are considered AQEC; the remainder of this technical specification only addresses non-military specification

parts.

Parts qualified to AEC-Q100, grade 0 through to grade 3 are considered AQEC. For those

applications where a 0 °C to +70 °C temperature range is appropriate, grade 4 is also

considered to be AQEC. The users should document that the grade category used is

compatible with the application in accordance with their IEC TS 62239-1 electronic

components management plan (ECMP).

4 Technical requirements
4.1 AQEC plan
The processes used to ensure compliance with the following requirements shall be

documented by the AQEC manufacturer and included in their AQEC plan. These requirements

---------------------- Page: 11 ----------------------
– 10 – IEC TS 62564-1:2016 © IEC 2016

identify the additional processes, documentation and procedures required to supply a

manufacturer's COTS part as an AQEC. The plan includes, but is not limited to, identifying

data sheet parameters and/or conditions that are different for the AQEC versus the COTS

part. These differences shall be identified and the data made available upon request.

4.2 AQEC documentation
4.2.1 General

For an avionics customer, the information supplied by the AQEC manufacturer will be

normally utilised and retained in accordance with the customer electronic component

management plan (see IEC TS 62239-1).
4.2.2 AQEC data sheet

The AQEC manufacturer shall provide and maintain under revision control a data sheet that

includes operating characteristics, as well as physical characteristics. Any known

environmental limitations applicable to the application being addressed (see 4.3.1.2) shall be

identified. This documentation shall specify the form, fit and function for a given part number.

This baseline shall not be changed without proper notification (see 4.7). Use of a unique

published or posted AQEC data sheet is encouraged. As a minimum, the AQEC manufacturer

shall document, individually or by family,
a) the functional operating temperature range;

b) the defined performance (mechanical and electrical) at the operating temperature range;

c) the maximum storage temperature;
d) the maximum operating junction temperature or operating case temperature;
e) the defined lead material, underplate, and termination finish;
f) a package outline drawing;
g) the designation of applicable COTS data sheet (or AQEC unique data sheet, as
applicable) and reference to additional data, if applicable.
NOTE For further guidance, see Annex B.
4.2.3 Material content

For each AQEC covered by this technical specification, the manufacturer shall make

available, upon request, information that describes the material content of the part. Annex A

describes typical material content for an AQEC. Materials that are considered proprietary by

the AQEC manufacturer and are not designated hazardous, may be excluded from public

disclosure.
4.2.4 AQEC visibility

Each data sheet shall either state that the parts meet AQEC requirements (preferred) or

optionally, the component manufacturer may list on its website all the part numbers that are

AQEC or include an AQEC reference in a description of another compliant class of parts.

4.2.5 AQEC life expectancy

The AQEC manufacturer shall identify the limiting wear-out failure mechanisms for a given

AQEC in a given application environment (see 4.3.1.2) for highly complex silicon based

technology components of feature size 90 nm and below including SRAMs, DRAMs
(SDRAMSs, DDR series), flash memories (NOR logic gate, NAND logic gate, MRAMS,

microprocessors, FPGAs). The AQEC manufacturer shall use acceleration models and failure

rate estimating and reporting methods vetted through peer reviewed publications or described

in industry standards and publications. This information shall be available on a website, data

sheet, alternative database, or provided on an as requested basis.
---------------------- Page: 12 ----------------------
IEC TS 62564-1:2016 © IEC 2016 – 11 –

NOTE 1 Examples of die related reliability wear-out failure mechanisms include electromigration, gate oxide

breakdown (TDDB), positive (PBTI) and negative bias temperature instability (NBTI), hot carrier injection (HCI),

etc.

NOTE 2 Examples of package reliability wear-out include mechanisms such as delamination, wire bond inter-

metallic formation, etc.

NOTE 3 Industry standards and publications which can assist include: JESD94, JEP122, JP001, JESD47,

JESD91, DSIAC (formerly RIAC) publication (”Physics of failure based handbook of microelectronics systems”).

The AQEC manufacturer should have reliability models for the lifetime limiting wear-out failure

modes that can predict the failure rate of that AQEC for a given end of lifetime frame and use

environment.
4.2.6 Device technology

Different technologies (e.g. bipolar and bi-CMOS; bulk CMOS and CMOS/SOS) shall not be

furnished under the same part number.
4.2.7 SEE data

Avionics equipment is subjected to ionising radiation that increases with altitude. At an

altitude of 40 000 feet (12,2 km) the radiation flux is approximately 300 times the atmospheric

radiation flux at sea level. The principal causes of atmospheric radiation single event effects

(SEE) on devices with geometric feature sizes below a micron are high energy neutrons and

thermal neutrons (see IEC 62396-1).

The following information is required, where available, for designers to assess the impact of

component SEE when using small geometric feature size devices, typically below 1 micron.

a) High energy neutron (>10 MeV) measured single event upset (SEU) cross section or the

terrestrially measured soft error rate (SER).

b) High energy neutron (>10 MeV) or terrestrially measured multiple cell upset (MCU) cross

section.

c) For memory devices, the way in which the bits in an individual word are stored within the

device, i.e. contiguously or non-contiguously.

d) The cross sections of any hard SEE, for example single event latch (SEL), single event

functional interrupt (SEFI) or stuck bits.

e) Thermal neutron sensitivity and the thermal neutron SEE cross sections. Where the

manufacturer uses Borophosphosilicate glass (BPSG) as a passivation and it contains

boron 10 or natural boron (20 % boron 10), this is to be declared.
4.2.8 Termination finish

Only one type of termination finish may be furnished on an individual part number supplied as

part of the AQEC program. As a minimum, a change to a different single lead finish or ball

alloy requires a PCN that includes the date and lot code of implementation. A new assigned

part number is preferred.
4.2.9 Third party part numbers

Where applicable, the data sheet shall state the third party part number (e.g. DSCC VID) for

the AQEC manufacturer’s part number (preferred). Optionally, the AQEC manufacturer may

list this data on their website or provide a link to the third party information.
