IEC 60352-5 defines the requirements for solderless wound connections, specifically where a solid round wire (the winding wire) is tightly wrapped around a terminal post (typically rectangular or square in cross-section). This paper explores the mechanical and electrical theory of connection formation, the critical parameters defined by the standard, the rigorous test sequences (mechanical, climatic, and electrical), common failure modes, and practical design guidelines for high-reliability applications (e.g., transformers, coils, motors, and automotive electronics).

offers a robust, solderless alternative—provided you follow the right standards. What is IEC 60352-5? IEC 60352-5 defines the requirements for solderless wound
Unlike soldering, wrapping requires no external heat. This eliminates thermal shock to sensitive components and removes the risk of flux contamination—critical for high-impedance circuits and medical electronics. This eliminates thermal shock to sensitive components and
