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.

b) when taping components with sprocket holes between its leads, care shall be taken that the
leads do not interfere with the sprocket holes;
c) for cases where inter-changeability cannot be guaranteed (see NOTE 1 and NOTE 2 in 4.2.1).
5 Taping
5.1 Taping dimensions
Taping dimensions shall be in accordance with Annex A. When the lead terminal is formed, the
type and dimensions of the forming shall be by agreement between the manufacturer and
customer.
5.2 Splices
Splices shall be at least as strong as the original tape and shall not hamper the transport and
the cutting of the tape. When splicing is applied, the misalignment of the holes on each side of

the splice shall not be more than ±0,3 mm in any direction. Splices shall not interfere with
sprocket feed holes nor shall the overall thickness exceed 1,5 mm. When used, staples shall
not interfere with the transport and cutting operations.
NOTE This includes deformation of lead ends due to shearing operations.

6.1 Polarization direction on tape
All polarized components shall be oriented in one direction. The cathode lead and, for
transistors (except for TO-92 packages), the emitter lead shall be the last one to leave the
package, unless otherwise specified in the detail specification. For TO-92 packages the flat
side shall be on the upper side of the tape.
6.2 Kinks or bends on tape
The wire terminations of the taped components shall be free from kinks or bends between the
seating or reference plane and the carrier tape.

6.4 Tape breaking force
The minimum breaking force of the tape shall be 15 N.
6.5 Tape material
The tapes shall be suitable to withstand storage of the taped components. The tape material
shall not migrate along the leads or give off vapours which may affect solderability or affect the
mechanical or electrical characteristics of component and leads by chemical action (e.g.
corrosion).
In addition, the hold-down tape shall not become detached so that the components do not
remain in position after storage. Any degradation of the carrier tape occurring during storage
shall not cause the tape to break or prevent the demounting of components during normal use.
Tapes in adjacent layers shall not stick together in the packing, e.g. because of exposed
adhesive.
The sprocket holes shall be free from burrs and traces of adhesive from the hold-down tape.
6.6 Hold-down tape
For tapes in fan-fold arrangement the hold-down tape shall preferably not become separated
from the carrier tape in the region of the fold. If this cannot be avoided, the value of the
maximum tape thickness shall not be exceeded.
6.7 Missing components
For automatic insertion, the number of empty places in the tape per reel or fan-fold
arrangement shall not exceed:
– three (3) missing components, when the component pitch is equivalent to one sprocket hole
pitch (see Figure 10);
– one (1) missing component, when the component pitch is equivalent to two sprocket hole
pitches or more (see Figure 10).
Empty places, for example programmed empty places at the bend or fan-fold packing, or for
other reasons, shall be by agreement between the supplier and the customer.
