PACKAGING OF COMPONENTS FOR AUTOMATIC HANDLING –

Part 2: Tape packaging of components with
unidirectional leads on continuous tapes

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.
IEC 60286-2 has been prepared by IEC technical committee 40: Capacitors and resistors for
electronic equipment. It is an International Standard.
This fifth edition cancels and replaces the fourth edition published in 2015. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) complete revision of structure;
b) consolidation of essential parameters and requirements in Clause 4.

PACKAGING OF COMPONENTS FOR AUTOMATIC HANDLING –

Part 2: Tape packaging of components with
unidirectional leads on continuous tapes



1 Scope
This part of IEC 60286 applies to the tape packaging of components with two or more
unidirectional leads for use in electronic equipment. It provides dimensions and tolerances
necessary to tape components with unidirectional leads. In general, the tape is applied to the
component leads.
It covers requirements for taping techniques used with equipment for automatic handling, pre-
forming of leads, insertion and other operations and includes only those dimensions which are
essential to the taping of components intended for the above-mentioned purposes.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:
• IEC Electropedia: available at https://www.electropedia.org/
• ISO Online browsing platform: available at https://www.iso.org/obp
3.1
packaging
product made of any material of any nature to be used in containment, protection, structured
alignment for automatic assembly, handling, and delivery
3.2
unguided lead
lead which is not held between carrier tape and hold-down tape
Note 1 to entry: See Figure 5.
3.3
crimp
cinch
purposely formed angular deformation, starting at the reference plane, in such a way that the
component bottom side does not touch the top surface of the printed circuit board after insertion
and therefore acts as a "stand-off"
Note 1 to entry: The formed crimp is available in different forms, see Figure 2.

---------------------- Page: 8 ----------------------
IEC 60286-2:2022 © IEC 2022 – 7 –
3.4
ordinate
straight line, perpendicular to the abscissa through the centre of the closest sprocket hole that
follows the component to be checked
3.5
abscissa
straight line, through the centres of the sprocket holes in the direction of unreeling
3.6
seating plane
bottom of the component body, including any projections
which support the component on the printed board
Note 1 to entry: See Figure 1
Note 2 to entry: A method for determining the seating plane is given in IEC 60717.
3.7
seating plane
plane that changes depending on the profile
of the crimp, the diameter of the leads and the hole size in the printed board
Note 1 to entry: See Figure 1 and Figure 2.
Note 2 to entry: For components with crimped (or preformed) leads, a reference plane is defined instead of a seating
plane.
Note 3 to entry: A method for determining the seating plane is given in IEC 60717.
3.8
reference plane
line parallel to the abscissa through the lowest centre of the radius of curvature of the bending
of the crimp
Note 1 to entry: See Figure 1 and Figure 2.
4 Dimensions and specific requirements
4.1 General
The symbols and dimensions are given in Figure 1 to Figure 6, Table 1, Annex A and Annex B.
All dimensions of the component leads have the centreline of the lead as the reference line.
4.2 Coordinate system
The coordinate system common to tapes and taped components consists of an abscissa and
an ordinate, both using the centre of the sprocket hole that follows the component to be checked
as the reference point (see Figure 1).
To determine the position of components in the taped condition, the seating plane shall be used
for components with straight leads, and the reference plane for components with crimped (or
otherwise formed) leads (see Figure 2).

The grid is defined as lead spacing e = 2,5 mm.
Components with a lead spacing of F = 3 × e may be delivered with the sprocket holes arranged
between the leads of the component (see Figure 3, Sketch B).
Components with a lead spacing of F = 8 × e to 11 × e may be delivered with one or two sprocket
holes arranged between the leads of the component (see Figure 3, Sketch B and Sketch C).

The leads of the taped components shall be free of kinks or bends from the seating plane or
reference plane downward to the carrier tape.
The leads of components shall be taped and handled so that lead spacing can easily be
maintained within tolerances after separation or removal from the tape.
The leads shall not interfere with the sprocket holes.
