VORTEILE VON PRESSFIT-STIFTEN

Higher reliability

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

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

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

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.
