IEC 60352-5 Overview

IEC 60352-5 is a standard for "Solderless connections - Part 5: Solderless crimped connections - General requirements, test methods and practical test requirements".

The standard specifies requirements for solderless crimped connections used in electrical and electronic equipment. It covers the design, testing, and inspection of crimped connections, including the materials, tools, and techniques used to create them.

Sample Piece: Crimped Connection Requirements

Here's a sample piece that demonstrates some key aspects of the IEC 60352-5 standard: iec 60352-5 pdf

Crimped Connection Requirements

1. General Requirements
   • Crimped connections shall be made using a suitable crimping tool and a compatible crimped contact or terminal.
   • The crimped connection shall be inspected visually and by pull test to ensure it meets the requirements of the standard.
2. Materials
   • The crimped contact or terminal shall be made of a material that is compatible with the wire and can withstand the environmental conditions of the application.
   • The wire shall be of a type and size suitable for the crimped connection.
3. Crimping Process
   • The crimping process shall be performed using a crimping tool that is calibrated and maintained according to the manufacturer's instructions.
   • The crimping tool shall be set to produce a crimp that meets the requirements of the standard.
4. Testing Requirements
   • Crimped connections shall be subjected to a pull test to verify their mechanical strength.
   • The pull test shall be performed using a tensile testing machine or a pull tester.

Practical Test Requirements

1. Sample Preparation
   • A sample of at least 5 crimped connections shall be prepared for testing.
   • The samples shall be prepared using the same materials, tools, and techniques as used in production.
2. Test Procedure
   • The crimped connections shall be subjected to a pull test by applying a gradually increasing tensile force until failure occurs.
   • The force required to cause failure shall be recorded and compared to the requirements of the standard.

This sample piece provides a brief overview of some key aspects of the IEC 60352-5 standard, including general requirements, materials, crimping process, testing requirements, and practical test requirements.

IEC 60352-5 sets global standards for solderless, press-in connections, defining requirements for high-reliability, eco-friendly cold welds in electronic components . The current 2020 edition provides comprehensive guidelines on materials, test methods for contact resistance, and connection procedures .

6. Practical Design Guidelines (Extending the Standard)

While IEC 60352-5 specifies tests, it doesn't provide exhaustive design rules. Based on industrial best practices:

1. Wire-to-post ratio
   Post diagonal should be ≥ 1.2 × wire diameter to avoid excessive stress concentration.

2. Wrap angle
   For automatic winding machines, a 270° initial wrap (3/4 turn) before the full set of turns prevents spring-back. General Requirements

3. Wire preparation
   For enameled wires: thermal stripping (solder pot at 400°C, 2–3 s) is preferred over mechanical scraping to avoid nicking.

4. Terminal plating
   Sn (tin) is suitable for ≤105°C. Ag (silver) or Au (gold) required for >125°C but risk of electromigration.

2.2 Physics of the Gas-Tight Joint

The standard implicitly relies on the theory of contact resistance:

• Applied tensile stress during wrapping creates plastic deformation of the wire at the terminal edges.
• This deformation produces multiple "micro-welded" contact zones free of insulating films.
• The spring-back of the wire maintains radial compressive force after winding, compensating for thermal cycling.

2. No Heat, No Flux, No Solvents

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.
