Method of aligning features in a multi-layer electrical connective device

A method of constructing a multilayer electric apparatus, comprising the steps of:

• providing a set of dielectric layers;
• forming a set of conductive features having positions and at least one fiducial marking having a position on each of said dielectric layers, wherein on each layer, said conductive features and said at least one fiducial marking are formed in mutual reference to each other so that said positions of said set of conductive features are known to a first tolerance relative to said position of said at least one fiducial marking;
• forming a set of pin holes in each of said dielectric layers, each said set of pin holes formed in relation to said fiducial marking for said dielectric layer and all of said sets of pin holes mutually having a substantially identical placement;
• providing a pin fixture having a set of pins that match said mutually identical placement of said pin holes;
• and
• arranging said dielectric layers on said pin fixture so that said set of pins extends through each of said sets of pin holes.
