=20 Hi all, I'm laying out my first "pro-quality" PCB with a PIC24FJ64, and have run into a little issue, but don't know if it's actually an issue or not.=20 In the spec sheet under External Oscillator Pins, it goes into great detail about creating an isolating GND pour around the OSC, and that this pour should be a separate entity from the "normal" GND pour that many (most?) use across the whole PCB. I've created this isolating pour top and bottom, but I seem to have a problem with Eagle PCB in that I seem to only be able to create one "GND" polygon per layer, so can't do an isolation pour as well as a pour for the rest of the board. Haven't found any threads on this topic elsewhere.=20 But the thing is, in any pictures I've found online of PIC-based PCBs, no-one seems to actually be doing this isolating "ring". So is it really something I should be concerning myself with? Or ideally, does anyone know a way of geting multiple "GND"-named polygons on a layer in Eagle?=20 Thanks for any input=20 Lee ------------------------- Msg sent via Webmail - http://hosting.myob.com/ --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
