Jandel Engineering Limited offers the Multiposition Probe stand as a solution for measurements on wafers up to 200mm diameter. The probe stand is available in two sizes at the same cost. One size is for wafers up to 150mm diameter and the second for wafers up to 200mm diameter. If small sized wafers are to be measured the smaller version is more suitable for placement of the wafers on the measurement table. The Θ movement clicks in four positions at 90 degrees and the linear movement in up to 10 positions, giving repeat placement accuracy of +/- 1mm.

Product FAQs
Who is Jandel Engineering Ltd?
Jandel Engineering was established in 1967. Prior to founding Jandel Engineering, Managing Director John Clark worked for A & M Fell in London. It was at this company that the first commercially available four point probe head, the 'Fell' probe head, was designed by John Clark and a colleague. Since this original design many improvements have been introduced.
Why use Jandel probes?
Jandel Probes offer the accuracy and perfection of more than 30 years experience. Tip radii and probe spacings are checked by interferometer and video inspection for certainty of accuracy. Spring loadings are checked by electronic force gauge.
Unique Standard specifications include:
1) Upper and lower guides are jewelled
2) Solid tungsten carbide needles for superior durability and accuracy
3) Teflon insulation giving minimum leakage
