I worked at a Flexible PCB hose for a couple of years, and all of the ones shown are single or double sided boards. You design it like a normal PCB, other than you make a much more intricate route pattern for the outline layer than a rectangle. You leave areas to make the folds or bends (don't place vias or components in those areas), and then you can crease them after assembly for a tight permanent bend, or leave them as is for an open/close movement (like the display cable on a laptop lid). If you need certain areas of the board to be rigid, you can mount it onto a sheet of Aluminum (adds stiffness and thermal dissipation) or take some FR4 hardboard to make a stiffener that is glued onto a small area (non conductive). Really the only layers you would need to add to your project are: A layer to indicate fold lines for bend locations (if needed) A layer for stiffeners (If needed) A layer for internal cutouts, made moments before the outline route (if needed) The only real challenge is for you to design a 2D object that will bend and flex to fit your 3D application ;-) Andy Miner References 1. http://www.allflexinc.com/origamiflex.shtml ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

The company, on a periodic basis, designs and fabricates unique, stand-along products constructed using traditional flexible circuit materials. All Flex displays these Origami Flex Circuits as various tradeshows and promotional events as well as providing them to prospect/customers as a collectible item. Click on the images to see the flat state of each product prior to folding. so it is still 'flat' for support in PCB? :-) ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
