A capacitor laminate is described either as an intermediate product for use in a capacitive printed circuit board or as part of the assembled printed circuit board in order to provide a bypass capacitive function for large numbers of devices mounted or formed on the printed circuit board, the capacitor laminate being formed from sheets of conductive material and an intermediate sheet of dielectric material forming the laminated capacitor as a structurally rigid assembly and facilitating its inclusion within the PCB, components of the capacitor laminate having selected characteristics whereby each individual device is provided with capacitance by a proportional portion of the capacitor laminate and by borrowed capacitance from other portions of the capacitor laminate, the capacitive function of the capacitor laminate being dependent upon random firing or operation of the devices. Methods of manufacture for the capacitor laminate as well as the capacitive PCB are also described. The capacitor laminate of the present invention is preferably formed with preferred surface treatment or surface characteristics on the conductive foils employed therein.
