Press-fit Technology

Press-fit technology was developed to enable reliable electrical connections between terminal pins and PCBs without soldering. Press-fit connector pins are widely used today in the automotive sector.

Press-fit pins, which feature an elastic press-fit zone, are cold-welded to the PCB when they are pressed in. This achieves a reliable electrical connection that fulfills the high automotive requirements without the drawbacks of soldering.

The Dietze Group has a proven track record with manufacturing high-precision press-fit connector pins and is your ideal partner for stamped terminal pins (EloPin), as well as wire-based terminal pins (Elbik-X-Press). For wire-based press-fit terminals, our unique swaging machinery is employed.

Dietze Group / Elbik was the first company worldwide to qualify the EloPin 04-06 press-fit zone, which is used for miniaturized packages.

Excellent Characteristics:

  • Proven and improved eye-of-the-needle design
  • Excellent electrical contact with the highest reliability
  • Low press-in force combined with high retention force and high mechanical stability
  • High elastic recovery
  • Good compensation for pitch tolerances
  • No nozzle effect
  • No tin chips during press-in process
  • Controlled tin displacement during press-in process
  • Gastight, corrosion-protected electrical connection
  • Low stress on the through-plated holes and the connected PCB traces
  • Suitable for engine compartment accessories with a temperature range of -40°C to +150°C
  • Tested according to and exceeding the standards of IEC 60352-5
