Abstract
A method for making a multilayer circuit board from circuit board layers, each including a dielectric layer and conductive traces thereon including a first metal. The method includes forming a through-via in a first circuit board layer, plating the through-via with the first metal, and coating a second metal onto the first metal of the first circuit board layer, the plated through-via, and the first metal. The method also includes aligning the first and second circuit board layers together so that the plated through-via of the first circuit board layer is adjacent a feature on the second circuit board layer, and heating and pressing the aligned first and second circuit board layers so as to laminate the dielectric layers together and form an intermetallic compound of the first and second metals bonding adjacent metal portions.
