Abstract
A printed circuit board composed of an epoxy impregnated nonwoven web substrate laminated to electrically conductive sheets is presented. The printed circuit board is flexible in the sense that it can be bent to any desired multiplanar shape and will retain that shape after installation as required by electronic interconnection systems. The printed circuit board also has improved thermal properties achieved through the addition of up to 70% by weight of low coefficient of thermal expansion (CTE) particulate fillers and/or the use of thermally stable reinforcement fibers in the non-woven web.
