Flexible Multilayer Circuit Board (SJ-00-0035)
Description This invention addresses the problem of limited interconnection space commonly encountered while assembling compact electronic devices. The size of a circuit board is determined primarily by the conductor density and the minimum space required for interconnection with other components. This invention transforms two-dimensional routing of conductors, associated with rigid circuit boards, into a three-dimensional geometry with the use of folded flexible circuits, thereby significantly minimizing the area needed to route conductors. Thus one achieves a structured routing of high-density interconnection conductors between multiple components at a higher density and lower cost than rigid multilayer boards. A demonstration model of this invention is available at St. Jude for those who are interested.
