Making use of our original Cold Heading technology, we manufacture components like middle flange pins, header pins, tapered pins with stopper function – all made from ultra-fine wire rods with excellent electrical characteristics – for a huge variety of applications.
We have cultivated this microfabrication technology over decades to deliver you probe pins, wire probes, cantilevers or contact pins without waste of material, compared to common methods like cutting, pressing or MEMS. To limit the contact point on the terminal tip, we additionally offer a hole-making process or barrel processing to make the surface smaller.
