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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

PRINTED BOARD ASSEMBLY PRODUCTS –
MANUFACTURING DESCRIPTION DATA AND
TRANSFER METHODOLOGY –
Part 2: Generic requirements
1 Scope and object
This part of IEC 61182 specifies the XML Schema that represents the intelligent data file
format used to describe printed board and printed board assembly products with details
sufficient for tooling, manufacturing, assembly, and inspection requirements. This format may
be used for transmitting information between a printed board designer and a manufacturing or
assembly facility. The data is most useful when the manufacturing cycle includes computer-
aided processes and numerical control machines.
The data can be defined in either English or International System of Units (SI) units.
1.1 Focus and intent
The generic format requirements are provided in a series of standards focused on printed
board manufacturing, assembly, and inspection testing. This standard series consists of a
generic standard (IEC 61182-2) that contains all the general requirements. There are four
sectional standards that are focused on the XML details necessary to accumulate information
in the single file, that addresses the needs of the design, fabrication, assembly and test
disciplines producing a particular product.
The sectional standards (IEC 61182-2-1 through IEC 61182-2-4) paraphrase the important
requirements and provide suggested usage and examples for the topic covered by the
sectional standard.
1.2 Notation
Although the data would be contained in a single file, the file can have different purposes as
described in Clause 4. The XML Schema used for this standard follows the notations set forth
by the W3C and is as follows:
element – Element appears exactly one time
element? – element may appear 0 or 1 times
element* – element may appear 0 or more times
element+ – element may appear 1 or more times
Any IEC 61182-2 file is composed of a high level element IEC 61182-2 that contains up to six
sub-elements:
Content – information about the contents of the 258X file
LogisticHeader – information pertaining to the order and supply data
HistoryRec – change information of the file
Bom – Bill of Materials (Material List) information
Ecad – Computer Aided Design (engineering) information
Avl – Approved Vendors List information

3 Documentation conventions
The XML file format standard and the XML Schema definition language standard, as defined
by the World Wide Web Consortium (W3C), have been adopted by IEC for use in the
IEC 61182 series of standards.
In addition to the text based schema notation, this document provides graphical
representation of the structure of the file format. The XML diagrams are designed to
effectively illustrate the structure and cardinality of elements and attributes that make up any
IEC 61182-2 file. The notation in the graphics does not provide a complete visualization of the
schema definition for the file format, but it does provide a good top down overview. Should
there be any conflict between the graphical notation and the schema notation, the
authoritative definition is the schema notation.
Table 1 provides an overview of the graphical notation used in the document.
—————————

61182-2  IEC:2006(E) – 11 –
Table 1– Graphical notation overview
This diagram depicts an element named
AnElement that is of type TypeB. There is one
attribute, named anAttribute, that is of type
double. The attribute is required.
Example:

Note that all attribute values must be enclosed in quotes, regardless of type.
This diagram depicts an element with two
attributes. The attribute anAttribute is required.
The “?” in the circle indicates that the second

attribute, anOptionalAttribute, is optional. Both
attributes are of type string.
Examples:


The element OneToManyOrElements is the
parent of an unordered list of one or more
instances of the elements AnElement and
AnothertElement. The “+” indicates the
occurrence is one to many and the angled lines

indicate this is a choice relationship (“|”)
between the children elements.
< OneToManyOrParentElement>…
The absence of an occurrence bubble declares
that one and only one occurrence are allowed.
The AnOrParentElement can have one of
AnElement or AnotherElement as a child
element.
The ‘*’ in the occurrence bubble indicates the
choice is from 0 to many.
This diagram depicts an element,
From2to3Elements. The element has no type
and no attributes. It can have from 2 to 3 sub-
elements of either AnElement or
AnotherElement.
This diagram depicts an element,
AParentElement, of type AParentElementType.
This element has one attribute,
attributeOfParent, which is optional. The lines
with square corners indicate that occurrences of
AnElement and AnotherElement must appear in
the order by the illustration on the right where
the top element is addressed first and
AnotherElement is addressed secondly.

This diagram depicts a type,
AParentElementType, that contains a sequence
starting with one of AThirdElement or AFourth
element followed by 0-n AnElement and an
optional final AnotherElement.

4 Requirements
The XML Schema contained in this document describes the structure of a generic computer-
aided manufacturing IEC 61182-2 exchange format. The document specifies data elements
specifically designed to establish the information exchange related to the data needed by
printed board manufacturing, and assembly including inspection of those products.
The XML Schema defines the configuration of mandatory and optional elements, as well as
mandatory and optional attributes. The Top Level (TopElement) of the schema contains six
major elements. The schema notation specifies that the 6 top-level elements are required to
appear in the order shown in Figure 1. The order of appearance in the file is significant. For
instance, the appearance of graphics on a layer is dependent on the order of appearance in
the file. The order is also important because elements often reference information that is
defined elsewhere in the file in order to eliminate redundancy within the file. The file is
structured to allow all references to be resolved in one pass.
An implementation of the XML Schema must be able to facilitate the reading and/or writing of
all characteristics defined within the requirements stated in the Mode function of this standard.
Some tools may have only read capability; some may have only write capability. Some tools
may have both read/write capability. All schema defined in the standard as mandatory (1-1, 1-
n occurrences) shall be executed as appropriate. Tool providers shall identify their capability
by Mode Level (Full, Design 1, 2 or 3, Fabrication 1, 2, or 3, etc.) plus 2581R (read-only);
2581W (write-only); or 2581RW (read and write).
Each element has a specific function or task. Accordingly, the information interchange for a
specific purpose is possible only if that element is populated. The ability to select those
characteristics that are appropriate for a given task makes the schema a robust methodology
for defining only those areas and characteristics that are necessary to produce a given
product. Figure 1 shows the children elements of the Top Element IEC 61182-2.

4.1 Rules concerning the use of XML and XML Schema
The rules required to define syntax and semantics of the 61182-2-X file format notation have
been simplified by the adoption of the W3C standards for XML Schema and XML file formats.
These two standards are well-specified by the W3C. The popularity of these standards has
lead to the development of many commercial and open source software tools and libraries
that conform to the W3C standards.
A IEC 61182-2 file begins with the <61182-2-X revision = ”1.0”> tag and end with the
tag. The content between these tags must match the .xsd definition of the
61182-2-X element as defined by the IEC 61182-2-1 through IEC 61182-2-4 XML Schema.

– 14 – 61182-2  IEC:2006(E)
4.1.1 File readability and uniformity
A valid IEC 61182-2-1 through IEC 61182-2-4 file must conform to the W3C Canonical XML
format. The format is defined by the http://www.w3.org/TR/xml-c14n specification. Software
tools exist that will take malformed XML and automatically generate Canonical XML.
4.1.2 File markers
An optional checksum can be appended following the tag. The checksum is an
MD5 message digest algorithm (see Internet RFC 1321: http://www.ietf.org/rfc/rfc1321.txt)
that is base64 encoded. The checksum starts with the “<” character of the <258X> tag and
ending with the “>” character of the closing tag. The checksum follows
immediately after the “>” character of the closing tag.
The digest provides a 128-bit checksum of the 61182-2-X file contents. The MD5 signature
must be base64 encoded (see IETF RFC 1421 for the base64 algorithm) to convert the MD5
signature to a US-ASCII, base64 string. An end of line character will indicate the end of the
base64 encoded MD5 signature.
4.1.3 File extension
The file extension for a 61182-2-X file is .cvg.
4.1.4 File remarks
The 61182-2-X format permits file remarks using the standard XML commenting notation.
They are only to be used to support debugging software. A p
