Conductive Coating Test Tool

A tool is described for obtaining the resistance of conductive paints which avoids the problem of the amount of pressure exerted on the part when making conductivity readings.

Current methods of making on line readings of resistance of conductive paints are not accurate or dependable. The reasons for this is that, when reading surface resistivity, the reading will vary with the amount of pressure that is applied and the distance between the testing probes along with the surface size of the contact points of the probes. The material that the probes are constructed of is another factor. That makes four variables when making a reading. The figure illustrates a sectional view of a tool that eliminates these four variables, thus, producing a reproducible test method which is the desired method when conducting a test or making an inspection.

In the figure, two plungers A are provided, each having gold plated contact points located 1/2" inch away from each other.

The phenolic housing B holds each plunger A 1" center to center.

Two springs C one for each plunger exert an appropriate fixed force so that the pressure will be constant with each use.

This probe can be used on all parts that require conductive coatings or platings.
