16、NNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 12-2: Soldering tests Test 12b: Solderability, wetting, soldering iron method 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of IEC technical committee
17、 48. It may also be used for similar devices when specified in a detail specification. The object of this part of IEC 60512 is to detail a standard test method to assess the solderability of the terminations of a connector that are designed to be soldered with a soldering iron and the soldering bath
18、 test method of IEC 60512-12-1 is not appropriate. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including
19、any amendments) applies. IEC 60068-2-20:1979, Environmental testing Part 2: Tests.

20、ose working surface is at 350 C, according to 4.7 of IEC 60068-2-20:1979 shall be provided. The size of this iron shall be that given in the detail specification. Non-activated flux as specified in 4.6.2 of IEC 60068-2-20:1979 shall be provided. 3.2 Preparation of specimen The specimen shall consist
21、 of a connector with its terminations. Unless otherwise specified in the detail specification, the terminations shall not be cleaned or degreased prior to the application of the solderability test. NOTE Care should be taken not to touch or otherwise contaminate the terminations to be tested. 3.3 Con
22、ditioning If accelerated ageing before testing solderability is to be applied, the ageing shall be done according to 4.5.3 of IEC 60068-2-20:1979, unless otherwise required by the detail specification. NOTE This is a period of 16 h at 155 C temperature according to 4.5.3 of IEC 60068-2-20:1979. EN 6

NOTE Soldering iron at 350 C 10 C, iron and solder applied to the termination for 2 s to 3 s; according to 4.5.3 of IEC 60
24、068-2-20:1979. 4.2 Measurements 4.2.1 Initial measurements Visual examination according to IEC 60512-1-1 shall be done. There shall be no defects, which would impair the validity of the test. 4.2.2 Final measurements Visual examination according to IEC 60512-1-1 shall be done. The soldered surface(s
25、) shall be examined at 10 magnifications. A surface shall be considered solderable if 95 % of the solderable area is covered with a smooth, bright, uniform coating of adherent solder. The remaining 5 % of the surface may show pinholes, voids, grainy surface or de-wetting areas, provided such defects
26、 are not concentrated in one area. It follows that if more than 5 % of the relevant surface(s) shows defects as described above, the surface is not considered solderable. There shall be no droplets or runs. NOTE These requirements are not in conflict with IEC 60068-2-20 but are additional and provid
27、e clarification. Record the number of specimens that exhibit less than 5 % of de-wetted or defective surface, and the number that exhibit 5 % or greater, de-wetted or defective surface. Also record any instances of droplets or runs. 5 Details to be specified When this test is required by a detail sp
28、ecification, the following shall be given therein: a) the areas of the specimen, which are to be considered as relevant for solderability testing; b) any preparation of the specimen if other than that in Clause 3; c) if pre-ageing is required; d) size of iron to be used (A or B); e) if the (preferre
29、d) requirements as detailed under 3.3 and 4.1 are not to be used, other requirements shall be given in the detail specification; e.g. higher temperatures than 350 C may be specified; f) any deviation from the standard test method. _ EN 60512-12-2:2006Annex ZA (normative) Normative references to inte
