Nickel-Plated Tungsten Carbide Needle for Semiconductor Testing

Micron-grade Conductive Pioneer Nickel-plated Custom Tungsten Carbide Needle

The precision probe with electroplated nickel layer, with ultra-low contact resistance of 0.02Ω and HV500 hardness coating, overcomes the wear and oxidation pain points of ordinary gold-plated needles, and achieves zero-attenuation transmission of microampere-level signals in the fields of semiconductor testing and medical electrodes.
