Abstract

A technique to characterize moisture in a dielectric layer of a printed circuit board is provided. A method comprises applying a test signal to test circuitry comprising a test capacitor that is formed with the dielectric layer of the printed circuit board; measuring at least one characteristic of a least one of signal transmission and signal reflection from the test circuitry; and determining, from the at least one measured characteristic, at least one parameter value indicative of moisture content in the dielectric layer.
