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.

INTRODUCTION

This Technical Report was developed by the technical committee 40 working group 36 on

components packaging, in which the members, such as mounter manufacturers, component

manufacturers and packaging material manufacturers, had proposed, considered and discussed

the possible standardization of the application of Auto Loading Feeder to enable automatically

exchange SMD continuous tapes, using paper carrier tape during mounter operation, aiming to

support IEC 60286-3, Edition 6, issued in 2019.

This document includes data expressed in the form of provisions, such as requirements or

recommendations. These data, however, do not claim to be provisions and are just suggested

as the results of the discussion.

Annex A
(informative)
Overview and features of Auto Loading Feeder

A characteristic example for operation of an Auto Loading Feeder is shown in Figure A.1. Just

after the components in a SMD tape get used up in the mounting process, another tape for re-

supply set at the filling-in position is automatically carried to the components supply position

and the pockets are automatically exposed. This results in re-supplying the components

automatically. That is to say, this mechanism enables to keep supplying components without

the conventional splicing work using a connection tape, which requires man-hours and specific

skills. In addition, it largely reduces work hours during the work at offline setup, because

inserting the top end of the tape in the re-supply position enables to supply the tape

automatically in the same way as during supplying components in the mounting process. Auto

Loading Feeder enables to boost up operating rate of mounters, save man-power and resources

in the components mounting field of electrical and electronic manufactures, and is expected to

get more popularization as the next generation supply system.

NOTE The splicing work is to connect the cut-off end of the trailer part of an in-use SMD tape and the cut-off tip of

the leader part of a SMD tape for re-supply, by using a connection tape.
a) Supplying components during the assembly production
b) Supplying tape at offline setup

Annex B
(informative)
Methods and mechanisms of automatically exposing
the pockets in using Auto Loading Feeder
B.1 General

The methods and mechanisms of automatically exposing pockets in using Auto Loading Feeder

are classified with some explanation as follows, but they are not specified as requirements. If

any of the following methods is applied to Auto Loading Feeder, attention is drawn to the

industrial property rights:

a) Single-door method with which only one sealed side of the cover tape is peeled off to expose

pockets (see Clause B.2);

b) Double-door method with which the cover tape is cut in its centre to expose pockets (see

Clause B.3).
B.2 Single-door method

The overview of the single-door method with which only one sealed side of the cover tape is

peeled off to expose the pockets is shown in Figure B.1.

B.3 Double-door method

The overview of the double-door method with which the cover tape is cut in its centre to expose

the pockets is shown in Figure B.2.

(informative)
Discussion for paper taping for Auto Loading Feeder
C.1 General

The details of discussion among the Project Group on the major requirements and required

dimensions and specifications for paper taping for Auto Loading Feeder, which were proposed

by the mounter manufacturers, are classified as follows:
a) Necessity of M and M as the cover tape sealed positions (see C.2.1);
1 2

b) Necessity of K as the distance between the upper side of carrier tape and the top surface

of a component (see C.2.2);
c) Sealing method for the cover tape (see C.2.3);
d) Dent of the cover tape over the pockets (see C.2.4);
e) Lower limit of the cover tape peel-off strength (see C.2.5);
f) Adhesion of components on the cover tape (see C.2.6);
g) Specified bending stiffness of the carrier tape (see C.2.7);
h) Fluff sneaking to the pockets at removal of the cover tape (see C.2.8);
i) Specified maximum trailer length (see C.2.9);
j) Fixing the tail end of the carrier tape (see C.2.10);
k) Cut shape of the tail end of the carrier tape (see C.2.11).
C.2 Discussion items
C.2.1 Necessity of M and M as the cover tape sealed positions
1 2

Necessity of M and M as the cover tape sealed positions was discussed as follows:

1 2
a) Background and discussed items for the requirements

Since M and M are important dimensions for the basic operation of Auto Loading Feeder,

1 2

which automatically exposes components, and it is impossible to realize to supply

components stably without the control of these potential dimensions, the mounter
manufacturers proposed M and M as the control values for every nominal component
1 2
dimensions (0402M, 0603M, 1005M, 1608M, 2012M, and 3216M). According to this
proposal, the components manufacturers and the packaging material manufacturers
discussed if they can deal with the values, reviewing them.
b) Resolved policy

It was decided that dimensions of the sealed positions required for Auto Loading Feeder are

described as the design values for every nominal component dimensions. Additionally, the

notes are added for additional recommended conditions and unsupported conditions.

c) Justification for the policy

IEC 60286-3 describes the cover tape peel-off strength and break strength provided that the

cover tape is generally removed by peel-off, but it does not specify any requirement or

statement on the sealed positions. The mounter manufacturers explained the Auto Loading

Feeder mechanism to the component manufacturers, so that the component manufacturers

understand it is most important to control th
