PACKAGING OF COMPONENTS FOR AUTOMATIC HANDLING –

Part 3: Packaging of surface mount components
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 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.
International Standard IEC 60286-3 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This fourth edition cancels and replaces the third edition issued in 1997. It constitutes a
technical revision.
This edition contains the following significant technical changes with respect to the previous
edition:
a) implementation of Type IV (adhesive-backed punched plastic carrier tape for singulated
bare die and other surface mount components);
b) minor revisions related to tables, figures and references.

NOTE The nominal dimensions of the component compartment should be derived from the relevant component
specification. The tolerances on the nominal dimensions of the compartment should be chosen so that the
components cannot change their orientation within the tape and can be easily removed from the tape, with the
following characteristics.
There shall be sufficient clearance surrounding the component so that
a) the component does not protrude beyond either surface of the carrier tape;
b) the component can be removed from the cavity in a vertical direction without mechanical restriction
after the top cover tape has been removed;
c) the rotation of the component is limited to a 10° max. tilt (see Figure 3, sketch A) and a 20°
max. planar rotation (see Figure 3, sketch B);
d) the lateral movement of the component is restricted to 0,5 mm max.(P ≥ 4), 0,3 mm max.(P = 2)
1 1
(see Figure 3, sketch C).
For components with either length or width dimensions of less than 1,2 mm, market trends are towards a planar
rotation limit of 10° max. and a lateral movement of 0,2 mm max. and a component rotation depends on the
agreement between suppliers and users. See also Clause 6 for die products.
For defined component positioning, the pocket positions should be defined to an origin point; in this case, the
index hole. Pockets should be positioned relative to this hole.
Preferred dimensions for components should be taken from the relevant IEC specifications.

NOTE The nominal dimensions of the component compartment should be derived from the relevant component

following characteristics.
There shall be sufficient clearance surrounding the component so that
a) the component does not protrude above the top surface of the carrier tape;
b) the component can be removed from the cavity in a vertical direction without mechanical restriction after the
top cover tape has been removed;
c) the rotation of the component is limited to a 10° max. tilt (see Figure 6, sketch D), a 20° max. planar rotation
for W = 8 mm and 12 mm and a 10° max. planar rotation for W = 16 mm and 24 mm (see Figure 6, sketch E);
d) the lateral movement of the component is restricted to 0,5 mm max. (see Figure 6, sketch F).
For components with either length or width dimensions of less than 1,2 mm, market trends are towards a planar
rotation limit of 10° max. and lateral movements of 0,2 mm max. See also Clause 6 for die products.
The centre of the component compartment is defined by P and F, relative to the sprocket holes, as shown in
