The 2020 revision introduced several significant updates to align with modern manufacturing:
To claim compliance with IEC 60352-5, manufacturers must subject their press-in connections to a rigorous matrix of environmental and mechanical tests. Environmental Stress Testing
Compliance with IEC 60352-5 ensures that solderless press-in connections maintain long-term electrical integrity and mechanical stability. By adhering to the PCB design tolerances, pin specifications, and testing protocols laid out in the standard, manufacturers can confidently eliminate soldering defects, lower production costs, and improve the reliability of complex electronic assemblies.
If you are working on a specific compliance project, let me know:
No flux cleaners, lead hazards, or volatile organic compounds (VOCs) are introduced into the factory environment. iec 60352-5 pdf
: The bending test was removed as it was tailored for older technologies no longer in common use. Why Press-in Technology Matters
Here's a sample piece that demonstrates some key aspects of the IEC 60352-5 standard:
defines the requirements and testing procedures for solderless press-in connections. This technology involves pressing a pin into a plated-through hole of a printed circuit board (PCB) to create a reliable electrical and mechanical bond without the use of heat or solder. Key Features & Technical Scope
: Includes two distinct schedules—one for qualification (testing individual press-in zones) and one for application (testing the implementation within a specific component). The 2020 revision introduced several significant updates to
Final surface finishes (e.g., HASL, Immersion Tin, Immersion Silver, or ENIG). 3. Mechanical Performance Metrics
Testing the "gas-tightness" of the contact zone. If the contact area is truly gas-tight, oxygen and corrosive gases cannot penetrate it, preventing oxidation of the electrical interface. Mechanical Endurance
The reliability of a press-in connection depends heavily on the quality of the PCB hole. The standard defines requirements for:
The standard demands that connections be processed in a "careful and workmanlike manner, in accordance with best practice". This includes: If you are working on a specific compliance
Key aspects covered include:
The standard outlines specific test schedules to validate performance, including:
The standard specifies rules for the pins being pressed into the board. These typically fall into two categories:
