Abstract

Disclosed is a surface resistance probe, which consists of a non-conductive block with a recessed area on two opposite sides. A flexible, conductive gasket is held in place within each recess and extends beyond the block. The gasket length is equal to the separation between the gaskets. (See Figure 1.) A conductive plate presses against the flat portion of the gasket and is secured with two or more screws or nuts and bolts. One or two meter leads are captured on each side of the block in a manner that insures a continuous conductive path from the area of the gasket in contact with the substrate being measured and the meter lead. A handle is attached to the block to hold and compress the gasket against the substrate to be measured. (See Figures 1 and 2 for a side and bottom view of the probe.)

A New Surface Resistance Probe Design

      Disclosed is a surface resistance probe, which consists of a
non-conductive block with a recessed area on two opposite sides.  A
flexible, conductive gasket is held in place within each recess and
extends beyond the block.  The gasket length is equal to the
separation between the gaskets.  (See Figure 1.) A conductive plate
presses against the flat portion of the gasket and is secured with
two or more screws or nuts and bolts.  One or two meter leads are
captured on each side of the block in a manner that insures a
continuous conductive path from the area of the gasket in contact
with the substrate being measured and the meter lead.  A handle is
attached to the block to hold and compress the gasket against the
substrate to be measured. (See Figures 1 and 2 for a side and bottom
view of the probe.)
