Summary: Dave tests the myth that plugging a PCB VIA with solder does nothing (or not much) to improve the current handling capability. Is manual wire feed-through any better? Does the industry rule of thumb of 0.5A per VIA have any basis? What is the typical plated VIA/hole thickness? http://saturnpcb.com/pcb_toolkit.htm Previous videos on PCB solder coating: http://www.youtube.com/watch?v=L9q5vwCESEQ http://www.youtube.com/watch?v=cScVqD6eIaU Does a PCB VIA halve in resistance like a PCB trace does when coated with solder?
