Method of Making a Circuit Board on a Mandrel

摘要

A non-planar printed circuit board has an interior surface and an exterior surface. Between the interior surface and exterior surfaces are layers of conductive and dielectric materials. Passive and active electrical components are embedded within the interior and exterior surfaces. A hollow region is defined by the interior surface of the non-planar circuit board. The non-planar printed circuit board is manufactured on a mandrel having a non-planar shape such as, for example, a cylinder or sphere so as to form a hollow, curved non-planar structure.

1. A method for making a non-planar printed circuit board upon a mandrel having a predetermined shape, said method comprising the steps of:
wrapping a base layer of a conductive material around the mandrel such that said base layer formed will assume a shape defined by an outer surface of the mandrel, the mandrel being non-planar; wrapping a dielectric lamination layer around said base layer of said conductive material; wrapping a second layer of conductive material around said dielectric lamination layer; exposing said base layer of conductive material, said dielectric lamination layer and said second layer of conductive material to a lamination process; and creating circuitry from said second layer of conductive material.
