ten prototypes of the mass-produced PCMCIA plastic surround from Litkconn had holes laser-cut to make space for the micro-sd, micro-hdmi and USB-OTG ports. the result was plastic under 1mm deep that had only around 0.5mm height below e.g. the micro-sd card and it of course snapped immediately. as a result we considered very thin metal sheet (thick foil in effect) that could be stamped (or laser cut) and was effectively a "metal sticker" that could go over the end and be bent round. probably even by hand. l. _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
