PRESSFIT TECHNOLOGY

SM Contact designs Pressfit pins solution for your electrical connection. Our engineers evaluate your components, define suitable pin parameters and test it.



Pressfit pins have an elastic eye-of-the-needle (EON) Pressfit zone which provides reliable connection without soldering.

PRESSFIT PIN ADVANTAGES
  • Higher reliability
    Higher reliability

    Size difference between PCB hole and Pressfit zone leads to Pressfit deformation during insertion. Compression of a pin guarantees reliable connection.

  • Qualification
    Qualification

    Pressfit pins 0.50×0.40 mm, 0.60×1.00 mm, 0.60×0.60 mm, 1.2×0.6 mm are qualified in accordance to EN 60352-5. It proved to have required contact resistance (< 0.5 mΩ), acceptable deformations and resistance to rapid temperature changes and climate sequences

  • Deformation and vibrations resistance
    Deformation and vibrations resistance

    Pin insertion doesn’t require additional soldering which means no thermal stress and no damage for components. As a result connection stays reliable under vibrations.

  • End-to-end supply
    End-to-end supply

    Reel is compact and easy to change. It fits all pin types and sizes. Compared to the bandolier pins, there is no excess material left from the end-to-end pins. No need to buy a new reel every time the pins run out: the reel is rechargeable. Only SM Contact supplies 0.4*0.5 Pressfit pins as end-to-end.
