Abstract:
A method of making a circuit board capacitor, comprising the steps of:forming a relatively thin film first dielectric layer on an electrically conductive first power plane;forming an electrically conductive second power plane over the first dielectric layer to create a composite of the first power plane, the first dielectric layer and the second power plane;forming an electrically conductive first via through the composite, which first via is formed to be electrically connected to the second power plane, and which first via is formed to be electrically insulated from the first power plane by a relatively thick second dielectric layer; andforming an electrically conductive second via through the composite, which second via is formed to be electrically connected to the first power plane, and which second via is formed to be electrically insulated from the second power plane by the relatively thick second dielectric layer.
