An electronic circuit including a substrate with an aperture therethrough is manufactured by cutting one or more slots in an edge of a slab of substrate, metalizing the slotted edge of the substrate and metalizing a mating edge of a mating substrate, securing together the metalized edges of the slotted substrate and mating substrate to create an aperture through the substrate from an upper surface to a lower surface thereof and creating a printed circuit pattern on one of the upper and lower surfaces of the combined substrate and metalizing the other surface of the combined substrate including a connection to the metalized edges. |
