16、vices from electrostatic phenomena General requirements 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-oper
17、ation 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
18、 “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 pre
19、paration. 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 con
20、sensus 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
21、 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
22、 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. Indepen
23、dent 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 lia
24、bility 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 (inc
25、luding 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 o
26、f 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. DISCLAIMER This Redline version is not an official IEC Standard and is
27、intended only to provide the user with an indication of what changes have been made to the previous version. Only the current version of the standard is to be considered the official document. This Redline version provides you with a quick and easy way to compare all the changes between this standar

IEC 61340-5-1:2016 RLV IEC 2016 5 INTRODUCTION This part of IEC 61340 covers the requirements necessary to design, establish, implement and maintain an
35、electrostatic discharge (ESD) control program for activities that: manufacture, process, assemble, install, package, label, service, test, inspect, transport or otherwise handle electrical or electronic parts, assemblies and equipment susceptible to damage by electrostatic discharges greater than or
36、 equal to 100 V human body model (HBM), 200 V charged device model (CDM) and 35 V on isolated conductors. Isolated conductors were historically represented by machine model (MM). The 35 V limit is related to the level achievable using ionizers specified in this standard. The MM test is no longer req
37、uired for qualification of devices, only the HBM and CDM tests are. The MM test is retained in this standard for process control of isolated conductors only. Any contact and physical separation of materials or flow of solids, liquids, or particle-laden gases can generate electrostatic charges. Commo
38、n sources of ESD include charged: personnel, conductors, common polymeric materials, and processing equipment. ESD damage can occur when: a charged person or object comes into contact with an ESD sensitive device (ESDS); an ESDS comes into direct contact with a highly conductive surface while expose
39、d to an electrostatic field; a charged ESDS comes into contact with another conductive surface which is at a different electrical potential. This surface may or may not be grounded. Examples of ESDS are microcircuits, discrete semiconductors, thick and thin film resistors, hybrid devices, printed ci
40、rcuit boards and piezoelectric crystals. It is possible to determine device and item susceptibility by exposing the device to simulated ESD events. The ESD withstand voltage determined by sensitivity tests using simulated ESD events does not necessarily represent the ability of the device to withsta
41、nd ESD from real sources at that voltage level. However, the levels of sensitivity are used to establish a baseline of susceptibility data for comparison of devices with equivalent part numbers from different manufacturers. Three different models have been used for qualification of electronic compon
42、ents human body model (HBM), machine model (MM), and charged device model (CDM). In current practice devices are qualified only using HBM and CDM susceptibility tests. This standard covers the ESD control program requirements necessary for setting up a program to handle ESDS, based on the historical
43、 experience of both military and commercial organizations. The fundamental ESD control principles that form the basis of this standard are as follows. Avoid a discharge from any charged, conductive object (personnel and especially automated handling equipment) into the ESDS. This can be accomplished
44、 by bonding or electrically connecting all conductors in the environment, including personnel, to a known ground or contrived ground (as on board ship or on aircraft). This attachment creates an equipotential balance between all conducting objects and personnel. Electrostatic protection can be maint
45、ained at a potential different from a “zero” voltage ground potential as long as all conductive objects in the system are at the same potential. Avoid a discharge from any charged ESD sensitive device. Charging can result from direct contact and separation or it can be induced by an electric field.
46、Necessary insulators in the environment cannot lose their electrostatic charge by attachment to ground. Ionization systems provide neutralization of charges on these necessary insulators (circuit board materials and some device packages are examples of necessary insulators). Assessment of The ESD ha
47、zard created by electrostatic charges on the necessary insulators in the work place is required assessed to ensure that appropriate actions are implemented, according to the risk. Once outside of an electrostatic discharge protected area (hereinafter referred to as an EPA) it is often generally not
48、possible to control the above items, therefore, ESD protective packaging may be required. ESD protection can be achieved by enclosing ESD sensitive products in static protective materials, although the type of material depends on 6 IEC 61340-5-1:2016 RLV IEC 2016 the situation and destination. Insid
49、e an EPA, static dissipative materials may provide adequate protection. Outside an EPA, static discharge shielding materials are recommended. Whilst all of these materials are not discussed in this standard, it is important to recognize the differences in their application. For more information see IEC 61340-5-3. Each company has different processes, and so will require a different blend of ESD prevention measures for an optimum ESD control program. It is vital that these Measures are sh
