How to distribute power to multiple devices on a PCB
When wiring a prototype PCB, I use bare solid wire to make the connections. I use 24 AWG for most connections. Sometimes I use 20 AWG or 16 AWG for ground and power buses, or high current paths. You can probably use 24 AWG for everything. 24 AWG is a personal preference, you could probably use a slightly smaller wire for your project.
For components with long leads, like resistors and capacitors, you can often stretch the component lead to the destination.
The connecting wire should be wrapped around the protruding lead to make a solid mechanical connection before soldering.
