A press-in connection is formed by pressing a specially designed pin (termination) into a plated-through hole (PTH) of a printed circuit board. Rigid vs. Compliant Pins
Improved annexes providing best practices for press-in tools and hole design. Requirements and Test Methods
For detailed information, specifications, and testing procedures, obtaining a copy of the IEC 60352-5 standard is essential. The standard can be purchased from the International Electrotechnical Commission (IEC) website or other authorized distributors. Having access to the IEC 60352-5 PDF allows professionals to delve into the specifics of the standard and apply its guidelines in the design, production, and testing of solderless connections.
: Added definitions for various "board" types, recognizing that press-in technology is now used on non-printed board materials. iec 60352-5 pdf
Compliant press-fit pins accommodate PCB manufacturing variances naturally, creating a highly repeatable and automated assembly process.
The design of the press-in zone is proprietary to various connector manufacturers (e.g., "Eye of the Needle," T-com, Action Pin). However, they must all comply with the mechanical performance thresholds of IEC 60352-5. The pin materials are typically high-conductivity copper alloys coated with tin or gold to prevent oxidation and ensure a gas-tight seal. 3. The Qualification and Testing Process
To help me tailor any further technical specifications or testing details, could you share a bit more context? A press-in connection is formed by pressing a
The global electronics industry relies on solderless connections to manufacture reliable, high-performance circuit boards. Among these, press-fit technology stands out for its mechanical strength and electrical integrity.
The standard provides not only strict requirements but also practical guidance for design and implementation, acting as a bridge between design engineering and manufacturing quality control. Key Aspects of the IEC 60352-5 Standard
Implementing designs that meet IEC 60352-5 allows manufacturing facilities to unlock significant advantages over traditional wave or selective soldering: : Added definitions for various "board" types, recognizing
IEC 60352-5 plays a vital role in standardizing solderless connections for coaxial cables and twisted wire pairs on solderless connectors. By ensuring that these connections meet specific requirements for electrical performance, mechanical strength, and environmental resistance, the standard contributes to the reliability and safety of electrical and electronic equipment. Manufacturers, engineers, and quality assurance personnel rely on IEC 60352-5 to ensure that solderless connections are made to the highest standards of quality and performance.
IEC 60352-5 offers a reliable framework for solderless wound connections used in electromagnetic components. Its strength lies in clear pass/fail criteria for environmental and mechanical stresses. However, successful application requires understanding the metallurgical interaction between wire and terminal, proper winding tension control, and suitable post-plating selection. When these factors align, the wound connection achieves contact resistance and mechanical stability comparable to welded joints, without heat-induced damage to magnet wire insulation.
