Claims
- 1. 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.
- 2. The method of claim 1, further including the step of forming at least one plated via to electrically connect a conductive feature on a first dielectric layer with a conductive feature on a second dielectric layer.
- 3. The method of claim 1, wherein after said step of arranging said dielectric layers on said pin fixture, one of said dielectric layers is on top of said stack and wherein said top dielectric layer includes a set of contact pads.
- 4. The method of claim 3 wherein each of said contact pads is electrically connected to a conductive feature on a dielectric layer that is not said top dielectric layer, by forming vias plated with conductive material.
- 5. The method of claim 4 wherein each said conductive feature is more specifically a conductive trace terminus, and wherein each conductive trace terminus is mutually electrically isolated from all of the other electrical trace termini, so that an interconnective device is formed having an array of electrical contact pads each connected to a different conductive trace.
- 6. The method of claim 5 wherein each conductive trace terminus is a first conductive trace terminus and wherein each conductive trace leads to a second conductive terminus that is adapted to be easily connected to some additional electrical circuitry.
