Ensure that VCC and GND are labeled correctly (everywhere).Use buses – Must label all signals pulled from buses.For large complicated designs, connect by net rather than by connection.Use NetLabels to label all wires – Can make your life easier in PCB layout.

Use multi-sheet schematics for large designs.Testing – Test points on power lines – Test points on important signals – Use Power LED (for basic signs of life).Power – Use bypass caps for all ICs – Use large filter cap on power supply.Rat’s Nest – point-to-point drawings of all un-routed connectionsįind in Altium libraries Draw your own Double-check the pins Connect “hidden” pins to the correct net.Mil – 1/1000 of an inch (don’t confuse with mm).Via – plated through-hole in PCB to connect traces on 2 sides.Pad – metal on PCB where component is soldered.Trace (track) – metal connections on PCB between components.

Net – representation of a signal (wire) and all of its connections.
