<p>A printed circuit board composed of a low Tg epoxy filled with a low CTE filler in the range of 45 to 65 % by volume and laminated to electrically conductive sheets is presented. The printed circuit board of this invention does not include any woven or nonwoven fabrics. 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.</p> |
