The standard mandates strict dimensional tolerances for the PCB holes, as a deviation of even a few micrometers can ruin the connection. The raw hole size before plating.
The significance of IEC 60352-5 lies in its contribution to ensuring the quality and reliability of electrical connections in a wide range of applications, from consumer electronics to industrial equipment. By standardizing the requirements for solderless connections, IEC 60352-5 helps manufacturers design and produce equipment that is safe, durable, and performs as expected. iec 603525 pdf
It defines procedures for measuring press-in force (insertion) and push-out force (retention). The 2020 edition introduced requirements for graphical documentation of these force profiles. The standard mandates strict dimensional tolerances for the
