MODEL SPP1: SINGLE-POINT PEN PROBE
Resistance to ground measurement for small piece parts
Introduction:
This test will measure resistance from various points on the top surface
of the piece part to the conductive platform that the bottom surface of the
sample is sitting on. The purpose of this test is to determine the ability of
the piece part to dissipate electrostatic charge from it surface to a fixture
or tool. The same possible current paths as the last section and all of
them will contribute to the charge dissipation characteristics of the
sample, as shown on the schematic below by Ben Baumgartner
(ESDiscovery 2000).
In this case, however, we want the edges to contribute to the readings.
For best result, the conductive platform should be larger than the
sample.
Procedures: Test procedure is the same as that for planar materials.
