SIST EN 60512-12-3:2006 is the Slovenian adoption of EN 60512-12-3:2006, published by SIST and aligned with IEC 60512-12-3:2006. It specifies a soldering test for connectors for electronic equipment: a method for checking whether connector terminations remain covered with solder after contact with molten solder under defined conditions.

What does SIST EN 60512-12-3:2006 specify?

SIST EN 60512-12-3:2006 specifies a standard test method for assessing solderability de-wetting on connector terminations. It is used for connectors within the scope of IEC technical committee 48 and may also be applied to similar devices when a detail specification calls for it.

The document is organized into:

  • Scope and object
  • Normative references
  • Applicability
  • Preparations
  • Method
  • Details to be specified

The foreword also says this part is to be read with EN 60512-1 and EN 60512-1-100, which explain the structure of the EN 60512 series.

What are the key requirements of SIST EN 60512-12-3:2006?

SIST EN 60512-12-3:2006 ties the de-wetting test to a prior wetting test and uses the same preparation. In practice, the test is not set up from scratch each time: the sample is prepared as for the earlier wetting test, so the result reflects the same termination condition.

Test sequence and conditions

Clause 5 requires the procedure from IEC 60068-2-58, Test Td, Clauses 8 and 9. The de-wetting test consists of two immersions of 5 s each. Immersion depth, heat shielding and flux are the same as those used for the preceding wetting test. For a lab or supplier, that means the test conditions must be controlled and consistent with the earlier solderability step.

Inspection before and after the test

Clause 5 requires visual examination according to IEC 60512-1-1 before and after the test. The initial inspection checks that there are no defects that would affect the validity of the test. The final inspection examines the soldered surfaces at 10× magnification. This matters because the acceptance decision depends on what can be seen on the termination surface, not only on the process settings.

Acceptance criterion for de-wetting

Clause 5 states that a surface is considered not to have de-wetted if 95 % of the solder area is covered with a smooth, bright, uniform coating of adherent solder. The remaining area may show pinholes, voids, grainy surface or de-wetting areas, provided they are not concentrated in one area. In practice, the reader must judge coverage and distribution of defects, not just whether any defect exists.

What the detail specification must state

Clause 6 requires any deviation from the test method to be given in the detail specification. The document also notes that other details come from the prior solderability test. For users, this means product-specific documents control any departures from the standard method.

What terms does SIST EN 60512-12-3:2006 define?

  • Termination - the connector end that is brought into contact with molten solder and is checked for solder coverage.
  • De-wetting - a condition where solder does not remain uniformly on the surface after immersion, so the coating is incomplete or uneven.
  • Wetting test - the prior solderability test in IEC 60512-12-1 or IEC 60512-12-2 that this de-wetting test follows when required.
  • Detail specification - the product-specific document that calls up the test and states any permitted deviations.
  • Test Td - the solderability-related method in IEC 60068-2-58 used for the procedure, including the immersion sequence.
  • Visual examination - the inspection method from IEC 60512-1-1 used before and after the test.
  • Solder area - the surface area on the termination that is assessed for coverage after testing.

Who uses SIST EN 60512-12-3:2006?

SIST EN 60512-12-3:2006 is used by connector manufacturers, test laboratories, quality engineers, and purchasers who need a repeatable way to check solderability de-wetting. It is relevant in electronics supply chains where connector terminations are soldered to equipment or assemblies.

In practice, users apply it for:

  • product qualification and verification
  • incoming or production testing
  • comparing solderability performance between connector designs
  • writing or checking detail specifications
  • documenting conformance for connectors and similar devices

What changed in SIST EN 60512-12-3:2006 from the previous edition?

SIST EN 60512-12-3:2006 cancels and replaces Test 12c of IEC 60512-6, issued in 1984. The document states that this edition is a technical revision.

Which standards are used with SIST EN 60512-12-3:2006?

  • IEC 60068-2-58 - provides Test Td, which supplies the procedure used for the de-wetting test.
  • IEC 60512-1-1 - provides the general visual examination method used for the initial and final checks.
  • IEC 60512-12-1 - provides the prior wetting test, solder bath method, when the de-wetting test follows it.
  • IEC 60512-12-2 - provides the prior wetting test, soldering iron method, when the de-wetting test follows it.
  • EN 60512-1 and EN 60512-1-100 - explain the structure of the EN 60512 series and are named as companion parts in the foreword.

What does the SIST EN 60512-12-3:2006 document contain?

SIST EN 60512-12-3:2006 contains a short test method rather than a long product specification. Its content centers on how to prepare the specimen, how to perform the two 5 s immersions, and how to judge the soldered surface under magnification.

It also states what the detail specification must declare when the method is used for a product. The document relies on IEC 60068-2-58 for the immersion procedure and on IEC 60512-1-1 for visual inspection.

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-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 to 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 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 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 efforts 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 e
