The key principle is : The compliant pin’s special geometry (often hourglass or eye-of-the-needle shaped) compresses as it enters the hole, then springs back to exert constant radial force against the copper plating. Why Use Press-In Technology? (The Advantages Over Soldering) Before diving into the standard’s specifics, it’s worth understanding why engineers choose DIN 60352-2 compliant connections over traditional soldering:
It specifies the requirements, dimensions, materials, and performance criteria for (also known as compliant pins) that are mechanically pressed into plated through-holes of PCBs. Unlike traditional soldering, the press-in process creates a cold-welded, gas-tight electrical connection using only controlled force. din 60352-2
Whether you’re working on automotive ECUs, industrial drives, or next-generation power modules, understanding and applying DIN 60352-2 will help you avoid field failures and improve manufacturability. The key principle is : The compliant pin’s

In the world of electronics manufacturing, reliability and efficiency are non-negotiable. As devices get smaller and more complex, engineers constantly seek connection methods that are robust, cost-effective, and easy to automate. Enter DIN 60352-2 —a critical but often overlooked standard that governs one of the most reliable joining techniques for printed circuit boards (PCBs): press-in technology .
