Napson 4-point resistivity / sheet resistance systems are using high performance probe heads which are made by Jandel Engineering Limited of England.
Jandel probe heads perform high precise measurement of resistivity and sheet resistance for silicon wafers, epitaxial layers, diffusion layers, ITO layers, metal layers and more, so that Jandel probes have a good evaluation for many years.
- Load (needle pressure) is always suitable since using V type spring
- Probe spacing accuracy and probe stability is excellent since anodized aluminum alloy upper and lower guides are jeweled
- Less damage of probe needle tips
- Solid tungsten carbide needles for superior durability
The probe type is chosen under the material of measuring sample, the surface state, the form etc.
