24、5 EN 61189-6:2006 INTRODUCTION IEC 61189 relates to test methods for printed boards and printed board assemblies, as well as related materials or component robustness, irrespective of their method of manufacture. The IEC 61189 series is divided into separate parts, covering information for the desig
25、ner 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 released. In some instances test methods developed by other TCs (e.g. TC 104) have been reproduced from existing
26、 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 with minor revision, those paragraphs that are different are identified. This part of IEC 61189 contains
27、test methods for evaluating materials used in manufacturing electronic assemblies. The methods are self-contained, with sufficient detail and description so as to achieve uniformity and reproducibility in the procedures and test methodologies. The tests shown in this standard are grouped according t
28、o the following principles: P: preparation/conditioning methods V: visual test methods D: dimensional test methods C: chemical test methods M: mechanical test methods E: electrical test methods N: environmental test methods X: miscellaneous test methods To facilitate reference to the tests, to retai
29、n consistency of presentation, and to provide for future expansion, each test is identified by a number (assigned 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 se
30、quence; that responsibility rests with the relevant specification that calls for the method being performed. The 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. Thu

36、ethods 3 Accuracy, precision and resolution Errors and uncertainties are inherent in all measurement processes. The information given below enables valid estimates of the amount of error and uncertainty to be taken into account. Test data serve a number of purposes which include: monitoring a proces
37、s; enhancing confidence in quality conformance; arbitrating between customer and supplier. In any of these circumstances, it is essential that confidence can be placed upon the test data in terms of accuracy; calibration of the test instruments and/or system, precision; the repeatability and uncerta
38、inty of the measurement, resolution; the suitability of the test instrument and/or system. 7 EN 61189-6:2006 3.1 Accuracy The regime by which routine calibration of the test equipment is undertaken shall be clearly stated in the quality documentation of the supplier or agency conducting the test, an
39、d shall meet the requirements of ISO 9001. The calibration shall be conducted by an agency having accreditation to a national or international measurement standard institute. There should be an uninterrupted chain of calibration to a national or international standard. Where calibration to a nationa
40、l 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 consistently found to be outside acceptable limits of accuracy shall be subject to shortened
41、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 for each instrument. These records should state the uncertainty of the calibration techniqu
42、e (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 limits. 3.2 Precision The uncertainty budget of any measurement technique is made up of bot
43、h 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 all uncertainties not subject to random fluctuation. These include: calibration uncertainties
44、; 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 uncertainties result from numerous sources but can be deduced from repeated measurement of a standard
45、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 atmospheric conditions reduce the repeatability of a measurement; uncertainty in discrimination, su
46、ch 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
47、the difference between the finest graduations of the scale of the instrument: i2r2st+ ) + ( = UUUU where Utis the total uncertainty; Usis the systematic uncertainty; EN 61189-6:2006 8 Uris the random uncertainty; Uiis the interpolation error. Determination of random uncertainties: random uncertainty
48、 can be determined by repeated measurement of a parameter, and subsequent statistical manipulation of the measured data. The technique assumes that the data exhibits a normal (Gaussian) distribution: nt U = rwhere Uris random uncertainty; n is the specimen size; t is the percentage point of the “t“
49、distribution from 3.5, statistical tables; is the standard deviation (n1). 3.3 Resolution It is paramount that the test equipment used is capable of sufficient resolution. Measurement systems used should be capable of resolving 10 % (or better) of the test limit tolerance. It is accepted that some technologies will place a physical limitation upon resolution (e.g. optical resolution). 3.4 Repor
