Abstract

A capacitor laminate is described either as an intermediate product or as part of the assembled printed circuit board (10) to provide a bypass capacitive function for devices on the printed circuit board (10), the capacitor laminate being formed from conductive sheets and an intermediate sheet of dielectric material forming the laminated capacitor as a structurally rigid assembly, components of the capacitor laminate having selected characteristics whereby each individual device (12) is provided with capacitance by a proportional portion of the capacitor laminate and by borrowed from other portions of the capacitor laminate, the capacitive function being dependent upon random operation of the devices. Methods of manufacture for the capacitor laminate as well as the capacitive PCB (10) and surface treatment thereof are also described.
