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.
