Abstract
A method of fabricating a printed circuit board power core is disclosed wherein ceramic particles that have a diameter that is approximately equal to the desired dielectric thickness are combined with dielectric powders that have a relatively very small size. To produce a dielectric core using this technique, a dielectric material mixture is applied between two conductor layers and bonded therebetween. This dielectric material mixture preferably has a concentration of large particles equal to the desired core thickness with a loading factor of large/small particles less than the maximum ratio needed to provide the desired dielectric constant, but greater than the ratio required to provide stability during the pressing and curing steps.
