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?<br />Does the industry rule of thumb of 0.5A per VIA have any basis?<br />What is the typical plated VIA/hole thickness?<br />Saturn PCB Toolkit: http://saturnpcb.com/pcb_toolkit.htm<br />Previous videos on PCB solder coating:<br />http://www.youtube.com/watch?v=L9q5vwCESEQ<br />http://www.youtube.com/watch?v=cScVqD6eIaU<br />Does a PCB VIA halve in resistance like a PCB trace does when coated with solder?<br />Forum: http://www.eevblog.com/forum/blog/eevblog-543-pcb-via-current-investigation/<br /><br />EEVblog Main Web Site:<br />http://www.eevblog.com<br />EEVblog Amazon Store:<br />http://astore.amazon.com/eevblogstore-20<br />Donations:<br />http://www.eevblog.com/donations/<br />Projects:<br />http://www.eevblog.com/projects/<br />Electronics Info Wiki:<br />http://www.eevblog.com/wiki/
