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.

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.

4 Overview of Auto Loading Feeder
4.1 Overview and features of Auto Loading Feeder

A characteristic example for operation of an Auto Loading Feeder is shown in Figure 2. 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. That 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

---------------------- Page: 10 ----------------------
IEC TR 60286-3-4:2021 © IEC 2021 – 9 –

skills. In addition, it enables to largely reduce work hours during the work at offline setup,

because just 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

resource 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 assemble production
b) Supplying tape at offline setup
Figure 2 – Operation and features when another tape is
re-supplied automatically by the Auto Loading Feeder
4.2 Methods and mechanisms of automatically exposing the pockets in using Auto
Loading Feeder

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

Feeder are classified as follows. See Annex A for details.

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

expose the pockets (see Clause A.2);

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

pockets (see Clause A.3).
---------------------- Page: 11 ----------------------
– 10 – IEC TR 60286-3-4:2021 © IEC 2021

IEC 60286-3 describes some requirements provided that the cover tape should be peeled off

and removed. Auto Loading Feeder mechanism, however, needs other requirements about the

sealed position of the cover tape on the carrier tape in order to maintain its stable operation

since the mechanism leaves the cover tape on the carrier tape.
5 Discussion items for requirements for emboss taping for Auto Loading
Feeder
5.1 General

New requirements for emboss taping for Auto Loading Feeder are to be considered in addition

to the requirements for the embossed carrier tape, with single round sprocket holes, with tape

pitches of 2 mm or more (nominal tape width: 8 mm only) among the tapes of Type 2a in

IEC 60286-3:
a) Required dimensions for the cover tape sealed positions (see 5.2);

b) Required dimensions for the distance between the upper side of the carrier tape and the top

surface of a component (see 5.3);
c) Necessity of M and M as the cover tape sealed positions (see 5.4);
1 2

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

surface of a component (see 5.5);
e) Necessity of K as the recessed part in a cross-bar section (see 5.6);

f) Necessity of K as the distance between the upper side of the recessed part in a cross-bar

section and the top surface of a component (see 5.7);
g) Sealing method for the cover tape (see 5.8);
h) Dent of the cover tape over the pockets (see 5.9);
i) Lower limit of the cover tape peel-off strength (see 5.10);
j) Adhesion of components on the cover tape (see 5.11);
k) Hole of the bottom of the pockets of the carrier tape (see 5.12);
l) Maximum length of the trailer (see 5.13);
m) Fixing the tail end of the carrier tape (see 5.14).
5.2 Required dimensions for the cover tape sealed positions

Required dimensions for the cover tape sealed positions for Auto Loading Feeder are shown in

Table 2.

NOTE 3 Sealing tape should be attached symmetric to the centre of the pocket.

Since the components can be inverted in the pockets and there are some restrictions in the assembly

manufacturing, the dimensions are shown as reference values in brackets. If the tapes do not meet these

dimensions, persons involved are suggested to discuss in advance whether it is possible to use Auto Loading

Feeder or not.

5.3 Required dimensions for the distance between the upper side of the carrier tape

and the top surface of a component in using Auto Loading Feeder

Required dimensions for the distance between the upper side of the carrier tape and the top
