20080251278 | Recycling Printed Circuit Boards - A method of recycling radio frequency printed circuit boards comprising track material printed on a laminate having a known dielectric constant using the steps of separating the substrate of one or more circuit boards from the track material; and processing the separated material to form a thin layer of substrate material suitable for relaminating with track material to provide a product for use in the manufacture of a further radio frequency printed circuit board. The method may separate the material from the laminate by grinding or use of an etchant. | 10-16-2008 |
