23、FOR SURFACE MOUNT SOLDER JOINT Part 1-1: Pull strength test 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-

24、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 t

25、o 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

26、 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

27、 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 eff

28、orts 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 Publicat

29、ions 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 provides no marking procedure to indicate its approval and

30、 cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 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 a

31、nd 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 Public

32、ation 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 Public

33、ation may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62137-1-1 has been prepared by IEC technical committee 91: Electronics assembly technology. This bilingual version, published in 2008-05, corresponds

34、 to the English version. The text of this standard is based on the following documents: FDIS Report on voting 91/681/FDIS 91/697/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard

The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication wi

38、gull-wing lead surface mounting components. The method is designed to test and evaluate the endurance of the solder joint between component leads and lands on a substrate, by means of a pull type mechanical stress. This test is suitable for evaluating the effects of repeated temperature change on th

39、e strength of the solder joint between component terminals and lands on a substrate. 2 Normative references The following referenced documents are indispensable for the application of this document.

46、mponent is pulled using a pulling tool at an angle of 45 to the board surface 3.3 pull speed moving speed of the pulling tool holding a gull-wing lead of a component mounted on board in pull strength test 4 General remarks The mechanical properties of the joint between leads to lands on a printed wi

47、ring board using lead-free solder are not the same for the joint using tin-lead solder due to the difference in composing elements of the solders. Thus it becomes important to test the mechanical properties of solder joints, using different solder alloys, and after temperature cycling stress have be

48、en applied. In this test method, the test specimens are mounted on a substrate either by flow soldering or by reflow soldering. The durability of the solder joints is evaluated first by exposing the electronic components to rapid changes of temperature and after that applying pull strength to the so

49、ldered joint. Users of gull-wing components subjected to these tests should check that the results ensure an adequate margin of attachment strength bearing in mind the mass of the component, the number of leads and the specified mechanical environment of the electronic assembly for which the component is intended. NOTE 1 The exposure temperatures in this test may exc
