How Should I Congure the Settings for a Collector with an Undercoat? Additionally, Is It Possible to Evaluate an
Undercoat + Collector Sheet That Lacks a Composite Layer?
8.7 How should I congure the settings for a
collector with an undercoat? Additionally, is it
possible to evaluate an undercoat + collector
sheet that lacks a composite layer?
When the collector has an undercoat, it is recommended to measure the sheet by ignoring the
thickness of the undercoat when you enter measurement conditions.
Because the thickness of the undercoat is negligible compared to that of the composite layer and
collector layer, with the result that the effect of current owing in the direction of the undercoat
surface can be ignored, the resistance value obtained by adding together the interface resistance
between the collector and the undercoat, the resistance of the undercoat itself, and the interface
resistance between the undercoat and the composite will be output as the interface resistance.
Since the undercoat layer is thin, it would be difcult for the instrument to evaluate the interface
resistance between the undercoat and the collector on a two-layer sheet made up of just an
undercoat and collector. Please evaluate the interface resistance based on the above interpretation
after applying the composite layer.
