IEC 60352-5:2012

Overview

IEC 60352-5:2012 is an international standard developed by the International Electrotechnical Commission (IEC) that sets the general requirements, test methods, and practical guidance for solderless press-in connections used primarily in telecommunication equipment and similar electronic devices. This edition, the fourth, updates and replaces the previous 2008 version by refining application guidance, updating testing methodologies, and revising design specifications to align with modern electronic manufacturing practices.

The standard focuses on press-in connections, which involve inserting a termination with a specific press-in zone into a plated-through hole on a double-sided or multilayer printed circuit board (PCB). The primary objectives of IEC 60352-5:2012 are to ensure electrically stable, mechanically sound, and environmentally reliable connections while providing consistent evaluation methods regardless of the tool design used in making these connections.

Key Topics

• Scope and Application
  Applies to solderless press-in terminations for telecommunication and electronics equipment involving similar termination techniques.

• Materials and Dimensions
  Specifies requirements for termination materials, dimensions of press-in zones, and plated-through holes. Includes guidance on surface finishes to optimize contact reliability.

• Test Boards Specifications
  Details materials, thickness, and tolerance ranges for test boards used during qualification and application testing to ensure repeatable results.

• Tools and Evaluation
  Defines requirements for the tools used in making press-in connections and establishes methods to evaluate their effectiveness in producing reliable terminations.

• Mechanical, Electrical, and Climatic Tests
  Introduces comprehensive testing procedures for mechanical strength, electrical performance, and environmental resistance of press-in connections under typical use conditions.

• Qualification and Application Test Schedules
  Provides structured test plans for individual terminations (qualification) and for terminations implemented within components (application), ensuring consistent validation.

• Practical Guidance and Annexes
  Includes annexes with practical advice on implementation and additional application notes to assist manufacturers and engineers in adopting best practices.

Applications

IEC 60352-5:2012 is highly relevant for:

• Telecommunication Equipment Manufacturers
  Ensures reliable signal and power transmission through solderless board-level press-in connections, critical for connectivity devices.

• Electronic Device Fabricators
  Supports the design and manufacturing of high-performance multi-layer PCB assemblies using solderless terminations for improved production efficiency and connection reliability.

• Connector Designers and Suppliers
  Provides guidance for designing press-in terminations that meet global quality standards and withstand mechanical and environmental challenges.

• Quality Assurance and Testing Labs
  Enables standardized testing methodologies for verifying the performance and durability of solderless press-in connections to industry benchmarks.

By adhering to IEC 60352-5:2012, users can achieve enhanced connection integrity without solder, reduce production complexity, and ensure compliance with international quality and safety norms.
