The object of IEC is to promole alI inlernationat co-operation on aII queslions concerning standardization in the etectrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technicat Specifications, Technicat Reports, Pubticly Availabte Specifications (PAS) and Guides (hereatter referred to as IEC Publication(sfl. Their preparation is entrusted to lechnical committees: any IEC National Committee interested in (he subject dealt with may participate in this preparatory work. Internattonat. governmentat and non 9overnmentat organizations Iiaising with the IEC atso participate in this preparation. tEC coltaborales closely with the International Organization for Standardization (ISO) in accordance with conditions delermined by agreement between the two organizations. 2) The formal decisions or agreements of tEC on technical matters express. as nearty as possibte. an inlernational consensus of opinion on the retevant subjects since each technicat commitlee has representation from alt interested IFC National Committees.

INTRODUCTION This part of IEC 61340 covers the requirements necessary to design, establish, implement and maintajn an 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 equal to ioo v human body modeL (HBM), 200 V charged device model (CDM) and 35 v on isolated conductors. lsolated conductors were historically represented by machine model (MM), The 35 v limit is related to the Ievel achievable using ionizers specified in this standard. The MM test is no Ionger required 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 oĺ materials or flow of solids, Liquids, or particle-laden gases can generate electrostatic charges. Common 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 exposed 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 groundeď



r o r



E



E w



Examples of ESDS are microcircuits, discrete semiconductors, thick and thin film resistors, hybrid devices, printed circuit boards and piezoelectric crystals. lt 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 devŕce to withstand ESD from real sources at that voltage level. However. the Ievels of sensitivity are used to establish e baseline of susceptibility data for comparison of devices with equivalent part numbers from different manufacturers. Three different models have been used for qualification of eíectronic components human body model (HBM). machine model (MM), and charged device model (CDM). ln current practice devíces are qualified only using HBM and CQM susceptibility tests. —



This standerd covers the ESD control program requirements necessary for setting tip a program to handle ESDS. based on the historical 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 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 maintained 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. Necessary insulators in the environment cannot lose their electrostatic charge by attachment to ground. lonization systems provide neutralization of charges on these necessary insulators (circuit board materials and some device packages are examples of necessary insulators). The ESD hazard created by electrostatic charges on the necessary insulators in the work place is 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 generally not 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 the situation and destination. lnside an EPA, static dissipative materials may provide

adequate protection. Outside an EPA, static discharge shielding materials are recommended. Whiist aU 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 wiII require a different blend of ESD prevention measures for an optimum ESD control program. Measures should be selected. based on technical necessity and carefully documented in an ESD control program plan. so that aU concerned can be sure of the program requirements. Training is an essential part of an ESD control program in order to ensure that the personnel involved understand the equipment and procedures they are to use in order to be in compliance with the ESD control program plan. Training s also essential in raising awareness and understanding of ESD issues. Without training. personnel are often a major source of ESO risk. With training, they become an eřfective first Iine of defence against ESO damage. w o

Scope



This part oĺ IEC 61340 applies to activities that: manufacture. process. assemble. install. package. Iabel, service, test. inspect, transport or otherwise handle electrical or electronic parts, assemblies and equipment with withstand voltages greater than or equal to ioo V HBM, 200 v CDM and 35 V for isolated conductors. ESDS with Iower withstand voltages may require additional control elements or adjusted Iimits. Processes designed to handle items that have lower ESD withstand voltage(s) can still claim compliance to this standard. This ştandard provides the requirements for an ESD control program. IEC TR 61340-5-2 provides guidance on the implementation of this standard.
