Abstract
PURPOSE: To check the thickness of the base material in a short time without destruction of the substrate, by applying an AC regulated voltage to copper foils on both faces of the copper-plated laminated plate and by measuring the current flowed in accordance with the electric capacity of the insulating base material.
CONSTITUTION: Copper-plated laminated plate 1 for printed circuit is shown as a capacitor, and ammeter 2 is arranged in series with the capacitor, and voltmeter 3 is arranged in parallel with the capacitor. The current flowed into the insulating base material when an AC regulated voltage is applied to the measure terminal is measured by ammeter 2 to check the distance between plate of the capacitor.
