28、heir method of manufacture. The standard is divided into separate parts, covering information for the designer and the test methodology engineer or technician. Each part has a specific focus; methods are grouped according to their application and numbered sequentially as they are developed and relea

29、sed. In some instances test methods developed by other TCs (e.g. TC 50) have been reproduced from existing IEC standards in order to provide the reader with a comprehensive set of test methods. When this situation occurs, it will be noted on the specific test method; if the test method is reproduced

30、 with minor revision, those paragraphs that are different are identified. This part of IEC 61189 contains test methods for evaluating printed boards and other forms of interconnection structures. The methods are self-contained, with sufficient detail and description so as to achieve uniformity and r

31、eproducibility in the procedures and test methodologies. The tests shown in this standard are grouped according to the following principles: To facilitate reference to the tests, to retain consistency of presentation, and to provide for future expansion, each test is identified by a number (assigned

32、 sequentially) added to the prefix (group code) letter showing the group to which the test method belongs. The test method numbers have no significance with respect to an eventual test sequence; that responsibility rests with the relevant specification that calls for the method being performed. The

33、relevant specification, in most instances, also describes pass/fail criterion. The letter and number combinations are for reference purposes, to be used by the relevant specification. Thus “3D02” represents the second dimensional test method described in this publication IEC 61189-3. In short, in th

34、is example, 3 is the part of IEC standard (61189-3), D is the group of methods, and 02 is the test number. A list of all test methods included in this standard, as well as those under consideration is given in Annex B. This annex will be reissued whenever new tests are introduced. 1 Scope and object

35、 This part of IEC 61189 is a catalogue of test methods representing methodologies and procedures that can be applied to test materials used for manufacturing interconnection structures (printed boards) and assemblies. 2 Normative reference The following normative document contains provisions which,

The information given below enables valid estimates of the amount of error and uncertainty to be

40、 taken into account. Test data serve a number of purposes which include: to monitor a process; to enhance confidence in quality conformance; to arbitrate between customer and supplier. In any of these circumstances, it is essential that confidence can be placed upon the test data in terms of: accura

41、cy: calibration of the test instruments and/or system; precision: the repeatability and uncertainty of the measurement; resolution: the suitability of the test instrument and/or system. 3.1 Accuracy The regime by which routine calibration of the test equipment is undertaken shall be clearly stated i

42、n the quality documentation of the supplier or agency conducting the test, and shall meet the requirements in ISO 9002, clause 4.11. The calibration shall be conducted by an agency having accreditation to a national or international measurement standard institute. There should be an uninterrupted ch

43、ain of calibration to a national or international standard. Where calibration to a national or international standard is not possible, “round robin” techniques may be used, and documented, to enhance confidence in measurement accuracy. The calibration interval shall normally be one year. Equipment c

44、onsistently found to be outside acceptable limits of accuracy shall be subject to shortened calibration intervals. Equipment consistently found to be well within acceptable limits may be subject to relaxed calibration intervals. A record of the calibration and maintenance history shall be maintained

45、 for each instrument. These records should state the uncertainty of the calibration technique (in % deviation) in order that uncertainties of measurement can be aggregated and determined. A procedure shall be implemented to resolve any situation where an instrument is found to be outside calibration

46、 limits. 3.2 Precision The uncertainty budget of any measurement technique is made up of both systematic and random uncertainties. All estimates shall be based upon a single confidence level, the minimum being 95 %. Systematic uncertainties are usually the predominant contributor, and will include a

47、ll uncertainties not subject to random fluctuation. These include: calibration uncertainties; errors due to the use of an instrument under conditions which differ from those under which it was calibrated; errors in the graduation of a scale of an analogue meter (scale shape error). Random uncertaint

48、ies result from numerous sources but can be deduced from repeated measurement of a standard item. Therefore, it is not necessary to isolate the individual contributions. These may include: random fluctuations such as those due to the variation of an influence parameter. Typically, changes in atmosph

49、eric conditions reduce the repeatability of a measurement; uncertainty in discrimination, such as setting a pointer to a fiducial mark, or interpolating between graduations on an analogue scale. Aggregation of uncertainties: Geometric addition (root-sum-square) of uncertainties may be used in most cases. Interpolation error is normally added separately and may be accepted as being 20 % of the difference between the finest graduations of the scale of the instrument.EN 61189-1:1997 BSI
