Electrical Contact Resistance of Coated Spherical Contacts
IEEE Transactions on Electron Devices, 2016The electrical contact resistance of two spherical contacts with coating is studied by using analytical method and finite-element method simulation software. The effects of contact radius, coating thickness, and the ratio of substrate to coating in electrical resistivity are evaluated over a large range of aspect ratios.

Contact resistivity measurement using four circular contacts
Solid-State Electronics, 1992Abstract In this paper, a simple technique for measuring contact resistivity of metallization is proposed. It makes use of four circular contacts, a structure which is simple to fabricate and requires only two measurement steps to obtain the contact resistivity.

Fluctuations of contact resistance in sliding contact
Wear, 1970Abstract Experiments were conducted with various metals of different properties in relative reciprocating linear sliding motion, which is important to sliding contacts used in electronic circuits, to examine noise due to irregular fluctuations of contact resistance caused by adhesive wear.

Contact resistance of thin metal film contacts
IEEE Transactions on Components and Packaging Technologies, 2006To be able to reduce the size of products having electronic devices, it becomes more and more important to miniaturize the electromechanical parts of the system. The use of micromechanical connectors and contact structures implies the need of methods for estimating the properties of such devices. This work will, by use of finite element modeling, treat

Thermal Resistance of Contacts
Review of Scientific Instruments, 1973In order to obtain accurate thermal resistance data for contacts under high loads (i.e., P/M > 2×10−3) it is not always necessary to employ a high vacuum for transverse thermal insulation, or a guard-heater arrangement.

This contribution aims at analyzing one case of resistance to interference, with the ultimate goal of contributing to a predictive theory of the conditions on contact-induced language change. This paper explores the possibility that interference is necessarily the result of structural reanalysis of strings of E-language already weakly generated in the ...

A Silicon - Metal Contact Resistance
Nature, 1947The rectifying action of a silicon crystal valve is a property of the contact between the silicon and a metal ‘cat's-whisker’. In order to complete the circuit it is necessary to have a second silicon – metal contact the resistance of which must be small compared with that of the rectifying contact, so that the rectifying action is not cancelled out by

Automated Contact Resistance Probe
Review of Scientific Instruments, 1963A probe is described that will determine (a) contact resistance with continuously increasing pressure from 0–1000 g, (b) contact resistance as a function of wipe distance at fixed normal load, and (c) the current-voltage properties of films from 0–200 V. In pressure and voltage modes, specimen positioning is entirely automatic and programmable.

Measurement of Contact Resistance
Review of Scientific Instruments, 1967An instrument for measuring the long term quality of electrical connecting devices is described. The parameter which controls this property is the contact resistance. In the instrument described, the contact and bulk resistance are separated by utilizing the difference in thermal response time between a contact spot and bulk metal.

Non-contact resistivity measurements
Proceedings, 1996Resistivity method finds wide application in many countries for the problems of near-surface geophysics. Frequently at field work by a resistivity method some problems of galvanic contacts with the ground occurs, for example at rocky surfaces, on dry sand, in permafrost regions, on a snow and an ice surface, on asphalt and concrete in cities, etc.
