Four Point Probe Head  jandelcylindrical.pdf [257K PDF file] regarding the Jandel Cylindrical Probe. The Cylindrical probe is used in all of the Jandel four-point probing systems (Multiposition Wafer Probe, Multi Height Probe, Microposition Probe, Multi Height Microposition Probe, Hand Applied Probe) except the Universal Probe which uses individual needles held in a guidance unit. The Cylindrical probe is the standard probe used in several OEM wafer mapping systems and it is ideal for building into custom engineered four point probe systems. It is available in a special version with modifications that make it usable in a VACUUM ENVIRONMENT. The Jandel Cylindrical Probe is capable of withstanding temperatures up to 120oC in the standard configuration. It is available in a version that can be used at temperatures up to 200oC. For higher or lower temperature use, please take a look at the Jandel MACOR Four Point Probe.The Jandel Cylindrical Probe has a 1" diameter body and is 1.9" high (25.4mm x 48.5mm high). The probe weighs 40g. The Cylindrical probe is available in one of three pressure ranges (10-30 grams per tip, 30-60 grams per tip, or 60-150 grams per tip) that can be user adjusted within the range. The following downloadable 65K PDF file, cyl-adj.pdf explains how to adjust the probe pressure within a given range. The probe tips are available in either a linear, square, or rectangle array. The price is the same regardless of whether it is linear, square, or rectangle array, however, square and rectangle arrays can only be built with needle spacing from 0.635mm up to 1.591mm, not close needle spacing of 0.5mm . Jandel probes are available with a small plastic shroud that attaches to the nosepiece to increase stability when applying the probe by hand.

[150K PDF file] If you prefer a weighted apparatus for manually positioning a four point probe head, without the need to apply pressure by hand, please see the Hand Applied Probe, which incorporates the Cylindrical probe. If you are planning on mounting the Cylindrical Probe onto an apparatus of your own design, the Mounting Adaptor (click here for 91K PDF file) can be used to simplify the job. If you would like to read an application note regarding the Jandel Cylindrical Probe, which information applies to most of the Jandel four point probes, that can be found here: cylindrical_app_notes.pdf [148k PDF file] Jandel four point probe heads are built with upper and lower jewel bearings and are built to 1% mechanical accuracy. Final testing involves the use of calibrated measurement instruments (electronic force gauge, video inspection system, interferometer) to verify tip radii, tip spacing, spring load, and tip planerity. |
