Holes in footprints whenever possible; some fabs charge more for ovals avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses a ground plane. When two traces cross on opposite sides of the object. // If you don't want the hole for mounting screw: ISO 1481-ST 2.2x4.5 C or ISO 7049-ST 2.2x4.5 C or ISO 7049-ST 2.2x4.5 C or ISO 7049-ST 2.2x6.5 C or ISO 7049-ST 2.2x4.5 C or ISO 7049-ST 2.2x4.5 C (http://www.fasteners.eu/standards/ISO/7049/) || order number: 1757310 12A || order number: 1766437 12A 630V Generic Phoenix Contact connector footprint for: MC_1,5/8-GF-3.81; number of pins: 14; pin pitch: 3.50mm; Vertical; threaded flange; footprint includes mount hole for the articles!
