Wire Probes
Wire Probes
- The use of tungsten material realizes high pin pressures that cannot be achieved with spring-loaded probes of the same size.
- Stable electrical resistance and high reliability with long life of over 1 million cycles.
- A high-precision masking position accuracy ±0.05mm.
- The electrodeposition coating smoothens the surface of the insulating coating, making it easier to install to the fixture.
- Fine pitch from 50 μm, tip style of hemispherical or conical.
