Refer to it for precise hole dimensions and plating specifications.

Resistance to corrosion, vibration, and thermal shock.

The standard ensures that press-in connections can withstand mechanical, electrical, and environmental stress.

In modern electronics manufacturing, the reliability of electrical connections is paramount. As electronic devices become more compact and complex, traditional soldering methods often face limitations regarding heat stress and assembly speed. Solderless connection techniques have emerged as a robust alternative. Among these, press-in connections are crucial, particularly in telecommunications and high-density computing equipment. iec 603525 pdf

To apply these specifications to a current project, verify if your manufacturing line requires the latest edition updates regarding automated optical inspection (AOI) or advanced surface finishes. If you want to look deeper into compliance, let me know:

If you are a testing lab, you may access standards through IECEE (IEC System of Conformity Assessment Schemes for Electrotechnical Equipment and Components).

Precise schematics showing how to fixture PCBs for pull-out testing. Refer to it for precise hole dimensions and

To avoid the “iec 603525 pdf” confusion in the future, use the following search strategies:

The standard, titled "Solderless connections - Part 5: Press-in connections - General requirements, test methods and practical guidance," provides the definitive technical framework for evaluating press-fit technology in electronic assemblies. As of 2026, the current version is Edition 5.0 (2020) , which modernized the standard to include a broader range of board materials beyond traditional printed circuit boards (PCBs).

While summary articles provide excellent context, engineering verification requires the official text. reducing stress on the PCB hole.

This comprehensive guide breaks down the core components of the IEC 60352-5 standard, its technical requirements, testing protocols, and how to practicalize its guidelines in modern electronics manufacturing. What is IEC 60352-5?

The IEC 60352-5 standard is designed to ensure that press-in connections maintain electrical stability and mechanical integrity under various environmental conditions. It is particularly valuable for industries requiring high-speed assembly and high-density packaging, including: Telecommunication switching equipment Computing and data storage systems Industrial automation machinery Automotive electronics

The 2020 edition , as this test was very specific for applications of press‑in technology that are no longer common. This simplification reduces the testing burden without compromising the ability to assess connection reliability.

The current version is the , published in 2020 . It cancels and replaces the fourth edition (2012) and incorporates a number of significant technical revisions, which we will examine in detail later.

Can be compliant (flexible) or rigid. Compliant pins are heavily favored today because they deform during insertion, reducing stress on the PCB hole.
