Overview

IEC TR 60286-3-3:2021 - "Packaging of components for automatic handling - Part 3-3: Packaging of surface mount components on continuous paper tapes for Auto Loading Feeder" is a Technical Report that describes possible requirements and recommendations for paper taping used with Auto Loading Feeder systems. The document focuses on SMD packaging on continuous paper tapes (nominal tape width: 8 mm), covering punched carrier tape with bottom cover tape (Type 1a) and pressed carrier tape (Type 1b) as defined in IEC 60286-3.

This TR supplements the IEC 60286 series by addressing special dimensions, sealing and handling considerations needed to support automatic tape re-supply and exposure mechanisms used in modern pick-and-place (mounter) equipment.

Key Topics and Technical Requirements

The report organizes technical content into requirements, figures and informative annexes. Major subjects include:

• Specified dimensions for paper taping relevant to Auto Loading Feeders (sprocket reference points, seal positions).
• Cover tape sealed positions and the required locations to ensure reliable operation during automatic exposure and feeding.
• Distance between carrier tape top and component top (clearance K) to avoid interference when cover tape is removed and feeders operate.
• Sealing method for cover tape: classifications (heat-welded vs adhesive) and relevant sealing considerations.
• Peel-off strength and acceptable limits to guarantee consistent tape opening without damaging components.
• Fluff and contamination control at cover-tape removal - prevention and acceptable behavior to avoid components becoming fouled.
• Maximum trailer length and leader/trailer design to ensure smooth automatic tape loading and exchange.
• Mechanical properties such as carrier tape bending stiffness, cover tape denting over pockets, and acceptable tail-end cut shapes.
• Informative annexes that explain Auto Loading Feeder mechanisms (single-door and double-door methods), discussion items, and a glossary of mounter/feeder terms.

Applications and Practical Value

This Technical Report is intended to enable reliable, high-throughput SMT assembly where tapes are automatically re-supplied or exchanged during production. Practical uses include:

• Designing paper-taped packaging for SMD resistors, capacitors and other leadless or stump-leaded components.
• Specifying cover tape sealing, peel strength and tape geometry to ensure compatibility with Auto Loading Feeder mechanisms.
• Reducing production interruptions caused by tape jams, fluff contamination or misfeeds during automatic tape exchange.

Who Would Use This Standard

• PCB assembly and SMT line engineers
• Mounter and feeder manufacturers (including Auto Loading Feeder implementers)
• Component and packaging material manufacturers
• Quality and process engineers responsible for tape-and-reel packaging compliance

Related Standards

• IEC 60286-3:2019 (Packaging of surface mount components on continuous tapes) - core reference.
• Other parts of the IEC 60286 series covering tape types, dimensions and handling.

Keywords: Auto Loading Feeder, paper taping, continuous paper tape, surface mount components, carrier tape, cover tape, IEC TR 60286-3-3, tape packaging, SMT feeders.

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.
