Abstract
In one embodiment, a peelable circuit board foil () has a metal support layer () and a conductive metal foil layer () bonded by an inorganic release material (). The conductive metal foil layer has a an exposed surface () that is coated with a high temperature anti-oxidant barrier () and has a roughness less than 0.05 microns RMS. In a second embodiment, the peelable printed circuit foil () has a crystallized dielectric oxide layer () disposed on the exposed surface of the conductive metal foil layer and an electrode layer () disposed on the crystallized dielectric oxide layer, forming a dielectric peelable circuit board foil () that may be adhered to a layer of a flexible or rigid circuit board, after which the metal support layer can be peeled away, leaving a capacitive structure including the metal foil layer, the crystallized dielectric oxide layer, and the electrode layer.
