Contact Probes
Contact Probes
An ultra-fine diameter wire probe suitable for inspecting electronic components with narrow-pitch electrodes.
Palladium alloys, copper-silver alloys, tungsten, rhenium tungsten, beryllium copper, etc. are used for the conductors.
Compared to spring type or cantilever type probes, this probe pin is better suited for narrow pitch and area arrays associated with higher integration.
There are few contact points and contact resistance is stable.We have also added a new contact probe that uses palladium alloy as the conductive material.

Features
- Using our unique manufacturing method, we are able to perform tip processing on extremely small parts.We specialize in ultra-thin diameter and short overall length probes.
- Our unique coating manufacturing method and peeling manufacturing method have achieved excellent insulation properties and a sharp coating interface.In addition, special surface treatment improves the lubricity of the insulation coating surface.
- Palladium alloy has the characteristic that the conductor is resistant to oxidation, resulting in improved contact resistance stability.Ideal for semiconductor inspections where oxidation is averse. We can handle diameters as small as 30μm.
