Abstract
Abstract A method for fabricating electrical component assemblies includes the steps: (a) providing a first electrode and a first electrical component and locating the electrode in a recess formed by the component to produce a first laminate subassembly, (b) providing a second electrode and a second electrical component and locating the electrode in a recess formed by the second component to produce a second laminate sub-assembly, and (c) locating said two sub-assemblies in mutually stacked relation, thereby to form a resultant assembly. The components are typically provided by deposition on the electrodes and to protrude edgewise thereof beyond selected edges of the electrodes, thereby to form electrical contacts, and said locating of the sub-assemblies is carried out to cause said contacts to protrude in at least two different directions from the resultant assembly. The component typically consist of dielectric material, and the electrodes are typically deposited in the form of electrically conductive ink.
