When I put LEDs, diodes, and other polarized parts on, I usually look at the schematics, look at the PCB layout, and decide which way I *think* it should go. Then I compare that with the silkscreen. If they match, on it goes. I did have one board that I did a 180 degree rotation of an AND gate. That swapped the power pins (single gate chip). A horizontal flip would have been the right thing to do. No pop, just smoke. _______________________________________________ geda-dev mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-dev
