Abstract
PURPOSE: To make possible the highly accurate and rapid measurement of the intermediate plating layer by regarding the plating element of the upper layer same as the element of the lower layer and measuring the film thicknesses of both plating layers, then measuring the film thickness of the upper layer separately and independently, converting the same to the film thickness viewed from the plating element of the lower layer and subtracting the same from the abovementioned measurement value.
CONSTITUTION: The total equivalent film thickness D01 of both layers 11, 12 viewing the plating element Au of the upper plating layer 12 from the same plating element Ni as that of the lower plating layer 11 is measured through fluorescent X-ray analysis by making use of the attenuation effect of the X-ray intensity from the underlying 10 metal. Next, the independent film thickness D12 of the upper plating layer 12 is measured similarly by the fluorescent X-ray analysis method. The film thickness D12 of the upper layer obtained by this measurement is converted to the film thickness D12' viewed from the plating element Ni of the underlying layer 11 and this is subtracted from the abovementioned total equivalent film thickness D01. From the difference thereof, the film thickness D11 of the lower plating layer 11 may be obtained.
