A method of constructing an electric apparatus, comprising the following steps. First, a set of dielectric layers is provided. Next, a set of conductive features and at least one fiducial marking are formed on a first one of the dielectric layers, in mutual reference to each other so that their relative positions are known to a first tolerance. Then, a set of pin holes is formed in each dielectric layer, each pin hole formed in relation to the fiducial marking for its dielectric layer and all of the sets of pin holes having a mutually identical placement. Finally the dielectric layers are arranged onto a pin fixture having a set of pins that match the mutually identical placement of the pin holes.
