Iec 60352-5 Pdf ((link)) Guide

The wording “telecommunication equipment and in electronic devices employing similar techniques” was removed and replaced by “electrical and electronic equipment and components”. This means the standard now openly applies to automotive electronics, industrial controls, consumer electronics, medical devices, and more.

: Requirements for the materials, dimensions, and surface finishes of the press-in zone. Hole Specifications iec 60352-5 pdf

Many European countries adopt the IEC standard as a "EN" (European Norm) and then as a national standard. The technical content is identical, but the title and number change. Hole Specifications Many European countries adopt the IEC

Terms and definitions for “board”, “hole”, and “metal board” were added to acknowledge that press‑in terminations are now used on many non‑printed board materials (e.g., metal‑core PCBs, insulated metal substrates). | Failure Mode | Root Cause | Detection

| Failure Mode | Root Cause | Detection per Standard | |--------------|------------|------------------------| | High initial resistance | Insulation not removed | Visual + initial R measurement | | Wire fracture at post edge | Too sharp edge radius | Microscopic inspection (non-mandatory but advised) | | Loosening under thermal cycling | Insufficient wire hardness (annealed wire) | Climatic test + pull test | | Creep relaxation | Wrong terminal alloy (pure Cu used) | Long-term damp heat | | Corrosion at interface | Incompatible plating (Ag + S environment) | Salt mist (optional extension) |

Manufacturers, quality engineers, and PCB assemblers use IEC 60352-5 to validate that press-fit technology meets safety and performance benchmarks.
