IPC-9797 (“Press‑fit for Backplanes and Other Boards”) covers similar technology but is more prescriptive regarding the design of press‑fit pins and board holes. , not design. Many manufacturers use both: the IPC document for design rules, and IEC 60352-5 for verification.
Unlike solder joints, which can be visually inspected for a shiny fillet, press-in joints are hidden inside the PTH. Quality assurance relies on:
What you are planning to use?
The represented a major technical revision. Compared to the 2008 edition, it deleted all tables with hole dimensions (because those dimensions were historically inherited from obsolete wire‑wrapping technology), added a full Annex A with practical application notes, included extra figures and a table to define tolerance ranges for test‑board holes, and introduced a requirement for the thickness of the test‑board. iec 60352-5 pdf
Some manufacturers assume that if a press‑fit pin looks mechanically sound and passes a quick continuity test, it is good enough. That assumption can be costly.
A successful press‑in connection, according to IEC 60352-5, must satisfy three primary requirements:
The standard does not simply list general requirements; it provides a systematic test methodology. For each test, it defines the test set‑up, the pre‑conditioning, the monitoring, the recovery time, the final measurement, the measurement uncertainty, and the details to be included in the test report. Unlike solder joints, which can be visually inspected
As of now, the 2015 version is the latest national adoption, although it is based on the 2008 IEC edition. It is important to note that a Chinese version of the newer 2020 IEC edition does not yet have a corresponding GB/T number.
The standard, titled "Solderless connections - Part 5: Press-in connections - General requirements, test methods and practical guidance," provides the international specifications for press-in technology used in electronics manufacturing.
The reliability of a press-fit connection depends entirely on the interference fit between the pin and the hole. The standard dictates strict tolerances for: Compared to the 2008 edition, it deleted all
Drilling and plating circuit boards within acceptable tolerances.
Visit the IEC webstore or your national standards body. Purchase the official IEC 60352-5:2020 PDF . Then, integrate its test methods into your production line. The cost of the document will be repaid many times over by reduced field failures and audited compliance.
Searching for is the first step toward mastering a critical manufacturing process. Solderless wrapped connections remain unmatched for reliability in high-end telecommunications, defense, and industrial controls. However, the standard is not a casual reference—it is a technical specification that demands proper procurement.
As of 2024/2025, the active version is (Edition 3.0). This edition consolidated amendments and added rigorous testing for fine-pitch terminals used in miniaturized electronics.
