I've found something similar that works well: http://www.homedepot.com/p/Phifer-0-140-.../100548686 The 0.140" diameter hollowcore spline is a bit too large, so 0.120" (3mm) would surely be the right size. A round versus rectangular shape also seems to work better, perhaps because it concentrates the compressive force for better conformance between the flex and PCB contacts. The last item needed is a stronger double-sided tape of proper width to hold the cords in place. Then perhaps I can ask for a few volunteers to get broader test results. isanchez: If you mean the recessed holes in the back cover that break out due to force and fatigue, I've had success gluing these pieces back in with an industrial cement meant for plastics. See here: http://eclecticproducts.com/products/e60...esive.html The trick for a strong bond is to use a small C clamp to apply a light pressure to the piece as the glue sets. Seems to hold up well to the force of a tightened screw. Good luck as well in your search for proper zebra connectors! The lack of these in small quantities is what led me to try the flex approach. ~Mark Remember kids, "In a democracy, you get the government you deserve." |
