Master the Standard: A Deep Dive into IEC 60352-5 for Solderless Press-in Connections

In the world of high-reliability electronics, the "perfect joint" doesn't always involve solder. IEC 60352-5 is the definitive international standard for press-in (press-fit) technology, a solderless method that is often 10 times more reliable than traditional soldering in demanding environments like automotive engine bays.

The current valid version is IEC 60352-5:2020 (Edition 5.0), which replaced the 2012 edition. Whether you're a PCB designer or a quality engineer, here is everything you need to know about the latest requirements. What is IEC 60352-5?

This standard defines the general requirements, test methods, and practical guidance for solderless press-in connections. A press-in connection is created by inserting a terminal with a specially shaped "press-in zone" into a hole in a board, creating a gastight, mechanically secure electrical path. Key Technical Updates in the 2020 Edition

The 5th edition introduced several critical changes to reflect modern manufacturing:

Expanded Scope: It now covers "electrical and electronic equipment and components" generally, removing the narrow focus on telecommunications.

New Materials: Added definitions for metal boards and other non-PCB substrates, acknowledging that press-in technology is no longer limited to standard FR4. Refined Testing:

Force Documentation: New requirements for graphing press-in and push-out forces to better analyze contact zone performance. iec 603525 pdf

Bending Test Removal: This test was removed as it no longer reflects common modern applications.

Copper Thickness: Updated the upper limit for copper thickness in plated-through holes to match current market trends. Critical Requirements for Success

To meet the standard, several components must be carefully qualified: Requirement Details Terminations Must have a suitable press-in zone (compliant or solid). Test Boards

Specific thickness ranges and hole tolerances are mandatory for repeatable testing. Tooling

Tools must make uniform connections without damaging the board or termination. Contact Resistance

Standardized methods are used to verify electrical stability across varying temperatures and climates. The Two Test Schedules The standard divides validation into two distinct paths: IEC 60352-5:2020 - iTeh Standards

IEC 60352-5: Solderless Connections - Part 5: Solderless Connections for Surface Mounting of Components Master the Standard: A Deep Dive into IEC

The International Electrotechnical Commission (IEC) has published a standard for solderless connections, specifically for surface mounting of components. IEC 60352-5 provides guidelines for the design, testing, and implementation of solderless connections for surface-mounted components.

This standard covers various aspects, including:

  1. Requirements for solderless connections: The standard defines the requirements for solderless connections, including the types of connections, materials, and testing procedures.
  2. Surface mounting of components: IEC 60352-5 provides guidelines for surface mounting of components, including the preparation of surfaces, component placement, and soldering.
  3. Testing and inspection: The standard outlines the testing and inspection procedures to ensure the reliability and quality of solderless connections.

By following the guidelines outlined in IEC 60352-5, manufacturers can ensure that their surface-mounted components are securely connected and meet the required standards for reliability and performance.

Key benefits of IEC 60352-5

  • Improved reliability and performance of surface-mounted components
  • Reduced risk of defects and failures
  • Enhanced quality control and testing procedures
  • Compatibility with international standards and regulations

Who should use IEC 60352-5?

  • Electronics manufacturers
  • Component suppliers
  • Contract manufacturers
  • Quality control and testing engineers

Where to find IEC 60352-5 PDF?

The IEC 60352-5 standard can be downloaded in PDF format from various sources, including: By following the guidelines outlined in IEC 60352-5,

  • The official IEC website
  • Online libraries and databases
  • Standards distributors and resellers

By accessing the IEC 60352-5 PDF, users can gain a comprehensive understanding of the requirements and guidelines for solderless connections in surface-mounted components.

Why Do You Need the IEC 60335 PDF?

Engineers, quality managers, and regulatory bodies require the official PDF for:

  • Product Design: Ensuring your appliance meets international safety margins.
  • CE Marking / CB Scheme Certification: Proof of compliance for global market access.
  • Factory Audits: Showing inspectors that your testing procedures align with the standard.
  • Legal Defense: In case of product liability lawsuits, using the official standard is mandatory.

What is IEC 60335?

IEC 60335 is a series of international standards that deal with the safety of electrical appliances for household and similar purposes. It covers everything from toasters and washing machines to electric tools and commercial catering equipment.

The standard is divided into two main parts:

  • Part 1 (General Requirements): The "base" standard. It covers common hazards such as electric shock, mechanical dangers, excessive temperature, radiation, and toxicity.
  • Part 2 (Particular Requirements): Specific amendments for different appliances. For example:
    • IEC 60335-2-5: Dishwashers
    • IEC 60335-2-6: Cooking ranges, ovens, and hobs
    • IEC 60335-2-14: Kitchen machines (blenders, mixers)
    • IEC 60335-2-30: Room heaters

2. Scope and Purpose

  • Objective: Define performance and test requirements for particular solderless connection types to ensure safety, reliability, and interchangeability in electrical assemblies.
  • Typical coverage: Materials, construction, crimp dimensions, mechanical strength, electrical resistance, current‑carrying capacity, environmental resistance (temperature cycling, vibration, humidity), and aging.
  • Application domains: Wiring harnesses, connectors in appliances, automotive wiring, industrial control equipment, and consumer electronics.

Part 3: Alternative Search – The IP Code (IEC 60529)

Some users searching "iec 603525 pdf" actually need IEC 60529 – the standard that defines Ingress Protection (IP) ratings (e.g., IP67, IP54). Why the confusion? Because the numbers 3, 5, 2, and 5 appear in IP codes like IP32 or IP52.

How to Get the Correct IP Standard PDF

To correctly obtain IEC 60529:

  1. Search for "IEC 60529 pdf" not "603525".
  2. Purchase from the IEC Webstore or national bodies (ANSI, BSI, DIN, JSA).
  3. Expect to pay between 200–400 CHF.

Part 8: Conclusion – Stop Searching for "IEC 603525 PDF"

To summarize:

  • IEC 603525 does not exist – it is a typo.
  • You almost certainly need IEC 60335 (household appliance safety) or possibly IEC 60529 (IP ratings).
  • If you manufacture or test dishwashers, your exact standard is IEC 60335-2-5.
  • Never download free "iec 603525 pdf" files from unknown sources – they are dangerous, illegal, or obsolete.
  • Purchase your PDF from the official IEC Webstore or a national body to ensure compliance, safety, and legal protection.

By correcting your search to "IEC 60335-2-5 PDF" or "IEC 60335-1 PDF", you will find the authoritative documents you need for product certification and engineering excellence.
