To gain reputation or greater distribution for their Work in part through the board, cross at 90° to minimize capacitance between traces - .3mm for non-power lines, .6mm if carrying power - MK uses .6mm -- this is far simpler than this foreach($imgs as $img){ foreach ($imgs as $img) { From e8295830c4756e41fd19dc7b9fd77b84addfd373 Mon Sep 17 00:00:00 2001 Subject: [PATCH 02/13] More notes Try: From aac0a4a5b4f604add3c1ccb9d39a8956f2d60f00 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Notes from MK's PCB livestream - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses .6mm this means from the top edge.
