Traditional double-sided or multilayer PCBs, as well as non-PCB materials like metal boards.

It specifies suitable materials and surface finishes to prevent corrosion and ensure stable electrical contact. Testing Methodologies iec 603525 pdf

While earlier editions focused primarily on telecommunication equipment, the IEC 60352-5:2020 edition expanded its scope to all . It specifically covers: Traditional double-sided or multilayer PCBs, as well as

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). For example, deformation of the drilled hole contour

The standard establishes strict criteria for the physical and electrical integrity of the connection:

It provides guidelines for hole diameters, tolerances, and plating. For example, deformation of the drilled hole contour in a plated-through hole must typically be less than 70 μm , with a minimum remaining plating thickness of 8 μm .
